I takt med att GIS (Grafiska InformationsSystem) blir allt vanligare och mer användarvänligt har WM-data sett att kunder skulle ha intresse i att kunna koppla information från sin verksamhet till en kartbild. Detta för att lättare kunna ta till sig informationen om hur den geografiskt finns utspridd över ett område för att t.ex. ordna effektivare tranporter. WM-data, som det här arbetet är utfört åt, avser att ta fram en prototyp som sedan kan visas upp för att påvisa för kunder och andra intressenter att detta är möjligt att genomföra genom att skapa en integration mellan redan befintliga system. I det här arbetet har prototypen tagits fram med skogsindustrin och dess lager som inriktning. Befintliga program som integrationen ska skapas mellan är båda webbaserade och körs i en webbläsare. Analysprogrammet som ska användas heter Insikt och är utvecklat av företaget Trimma, kartprogrammet heter GIMS som är WM-datas egna program. Det ska vara möjligt att i Insikt analysera data och skapa en rapport. Den ska sedan skickas till GIMS där informationen skrivs ut på kartan på den plats som respektive information hör till. Det ska även gå att välja ut ett eller flera områden i kartan och skicka till Insikt för att analysera information från enbart de utvalda områdena. En prototyp med önskad funktionalitet har under arbetets gång tagits fram, men för att ha en säljbar produkt är en del arbeta kvar. Prototypen har visats för ett antal intresserade som tyckte det var intressant och tror att det är något som skulle kunna användas flitigt inom många områden.

Full textAbstract:
A Component Oriented Software Engineering (COSE) modeling environment is
enhanced with the capability to import executable components and deliver
applications through their composition. For this purpose, an interface layer that
utilizes JAR libraries as components has been developed. Also, Domain Engineering
process has been applied to Geographical Information Systems (GIS) domain and
utilized towards converting the environment to a development framework. The
interface layer imports JAR libraries into the COSECASE tool, which is a graphical
tool supporting COSE approach and COSE Modeling Language (COSEML). As a
result, systems can be designed using abstractions and then implemented by
corresponding deployed components. Imported code is made available to the
COSECASE environment through this interface layer. Also, Domain Analysis,
Domain Design, and Domain Implementation phases of Domain Engineering process
have been applied to the GIS domain. Components developed in this Domain
Implementation phase have been imported into COSECASE. A simple GIS
application has been designed and generated through the interface layer of
COSECASE for demonstration purposes.

Neste trabalho, buscou-se o desenvolvimento e adequação de técnicas de análise morfométrica em Sistemas de Informações Geográficas. Como base de trabalho, foram utilizados os programas livres GRASS-GIS e a linguagem estatística R. Os parâmetros morfométricos estudados foram hipsometria, declividade, orientação de vertentes, perfis em varredura, densidade de lineamentos e de drenagem, rugosidade de relevo, isobases e gradiente hidráulico. A área de estudo localiza-se na borda leste do Quadrilátero Ferrífero (MG), e possui unidades geomorfológicas distintas: um relevo montanhoso a oeste (Serra do Caraça), separado por uma escarpa de centenas de metros de terrenos caracterizados por dissecação fluvial, que abrigam em sua porção central, um planalto sustentado por conglomerados ferruginosos cenozóicos. O elemento principal da análise morfométrica é o Modelo Numérico de Terreno (MDT), que pode ser interpolado a partir de curvas de nível ou de pontos cotados. Há ainda a possibilidade de utilizar MDTs produzidos pela agência espacial americana (NASA), disponíveis gratuitamente via internet. A metodologia proposta envolve principalmente operações básicas de SIG, como conversão entre formatos vetorial e matricial, operações matemáticas simples em mapas raster e interpolação de valores pontuais em superfícies contínuas. Análise de superfícies de tendência foi realizada para verificar a possibilidade de uso do método em estudos de morfotectônica. Foram ajustadas superfícies polinomiais de 1º a 6º grau, e as significâncias estatísticas de cada polinômio e do incremento do grau polinomial foram verificadas com análise de variância. Os mapas morfométricos produzidos permitiram a identificação de estruturas provavelmente relacionadas com a configuração atual da paisagem. Os mapas de resíduos para as superfícies de tendência mais representativas possuem boa correlação com as estruturas inferidas. A metodologia proposta pode ser adaptada aos diversos pacotes SIG existentes no mercado. O uso de programas livres e de código aberto garante o acesso a todos, e sua crescente popularização abre novas perspectivas nesse campo.This work aims on developing and adaptation of morphometric analysis in Geographic Information Systems. Free softwares GRASS-GIS and R statistical language were used as main applications. Studied morphometric parameters were hypsometry, slope, aspect, swath profiles, drainage and lineament density, surface roughness, isobase and hydraulic gradient. The study area is located in the eastern border of Quadrilátero Ferrífero (MG), and has distinct geomorphological units: a mountainous relief to west (Serra do Caraça), separated by a scarp with hundreds of meters of fall from fluvial dissected terrains, with a flat plateau in its central portion, the Chapada de Canga. The main element for morphometric analysis is the Digital Elevation Model (DEM), which can be interpolated form contours or scattered points. There is also the possibility of utilize NASA' s DEMs, freely available via internet. The proposed methodology deals mainly with basic GIS operations, like conversion between raster and vector, simple mathematic operations on raster maps and interpolation of discrete values into continuous surfaces. Trend-surface analysis was carried out o verify the possibility of use the method for morphotectonic studies. Polynomial surfaces from 1st to 6th degree were adjusted; the statistical significance of each surface and the significance of increasing polynomial degree were verified with analysis of variance. Produced morphometric maps allow identification of structures probably related with present-day landscape configuration. Residuals maps for most representative trend-surfaces keep good correlation with inferred structures. The proposed methodology can be adapted to the variety of GIS packages available in the market. The use of free and open-source softwares guarantees access to everyone, and its increasing popularization opens new perspectives in this field.

A fase inicial de um empreendimento mineiro demanda um forte investimento com retorno bastante incerto, pois é necessária a aquisição de dados para localizar, delimitar e estimar os volumes das reservas minerais de interesse. Visando reduzir estes custos e diminuir as incertezas características de uma fase em que se tem pouca informação, esta pesquisa propõe o uso de Open Source GIS, também conhecidos como Sistemas de Informações Geográfica de Código Aberto, combinado com a aquisição de dados geoespaciais gratuitos de fontes públicas e oficiais, para posterior processamento e refinamento de informações. Para a composição deste trabalho foi realizada aquisição de dados públicos disponíveis sobre a região dos corpos Pegmatitos da Fazenda Primavera, localizada na Província Pegmatítica da Borborema, no município de Tenório, Paraíba. Os dados foram utilizados para a produção e refinamento de informações como a delimitação e localização dos corpos, realização de estudos geomorfológicos, logísticos e estimação de volumes. Os processamentos das imagens e dados, além da confecção de mapas, e análises tridimensionais dos afloramentos foram executados em um único programa, o software livre Quantum GIS. Os produtos gerados permitiram concluir que é possível extrair e produzir informação de elevada qualidade a partir de dados disponíveis de forma gratuita, utilizando softwares oficiais, reduzindo os custos iniciais de um projeto de mineração, podendo continuar a ser utilizados nas fases posteriores, caso o empreendimento mineral se prove viável.
The initial phase of a mining project requires a strong investment with a very uncertain feedback because it is necessary the data acquisition to locate, define and estimate the volumes of mineral reserves of interest. In order to reduce these costs and reduce the characteristic uncertainties of a stage where there is little information, this research proposes the use of Open Source GIS (Geographic Information Systems), combined with the acquisition of free geospatial data from public and official sources for further processing and refinement of information. For the composition of this research it has been carried out the acquisition of public available information about the region of pegmatites bodies at the “Fazenda Primavera”, located at the Borborema Pegmatitic Province, Tenório county, Paraíba. The data have been used for the production and processing of information as the delimitation and location of pegmatites, realization of geomorphological and logistic studies, and estimation of volumes. The processing of the images and data besides maps making and threedimensional analyzing of outcrops were executed in a single program, the free Quantum GIS software. The created products allowed the conclusion that it is possible to extract and produce high-quality information from free available data, using official software, reducing the initial costs of a mining project, which may continue to be used in later phases if the mineral project proves to be feasible.

Full textAbstract:
A análise digital de terreno, também chamada de modelagem digital de terreno ou geomorfometria, é uma disciplina que faz uso de ferramentas das ciências da Terra, matemática, engenharia e ciência da computação para a quantificação de variáveis e parâmetros relacionadosà superfície topográfica. Atualmente, o único produto disponível para o estudo de formas de relevo em escala de semi-detalhe a regional, com cobertura quase global e produzido segundo uma única metodologia, portanto livre dos problemas encontrados em produtos cartográficos (qualidade dos mapa, disponibilidade, escala adequada ao estudo etc), é o modelo de elevação Shuttle Radar Topography Mission (SRTM). Este trabalho visou o estudo do relevo da região centro-leste brasileira por meio da caracterização morfométrica de modelos de elevação e da integração entre dados morfométricos, termocronológicos e geofísicos, bem como a avaliação da validade do uso de superfícies aplainadas em correlações estratigráficas regionais. Perfis morfológicos e mapas de orientação de vertentes evidenciam uma estruturação N-S das grandes formas de relevo do centro-leste brasileiro, além da presença de uma organização NW-SE das formas de relevo menores, principalmente na região sudeste, mas observável por toda a área de estudo. A distribuição espacial dos dados termocronolóogicos existentes no Brasil éé bastante heterogênea, com amostragem concentrada nas regiões sul-sudeste e nordeste. Os dados da região sudeste mostram que a ruptura continental não aparece como o evento de resfriamento mais importante, que é marcado pelo grande número de amostras com idades traços de fissão (TF) entre 60 e 80 Ma e que pode ser visto como um evento de soerguimento regional (acompanhado de intensa denudação), dada a variação das elevações das amostras nessa faixa de idade. A tendência de que amostras mais distantes da costa apresentem idades TF mais antigas é sutil. Os dados da região nordeste mostram uma tendência mais clara de aumento da idade com a distância da costa e um conjunto de amostras com idades ao redor de 100 Ma pode ser relacionado ao evento de ruptura continental. De maneira geral, a análise morfométrica não permitiu a identificação de extensas superfícies de aplainamento na área de estudo. As áreas essencialmente planas (com topografia muito suave) estão relacionadas a planícies aluviais (rios São Francisco, Araguaia, Tocantins), a bacias sedimentares cretáceas (Chapadão Ocidental da Bahia, Chapada do Araripe, Bacia Bauru) e a bacias paleozóicas com cobertura cretácea (Bacia dos Parecis), onde configuram superfícies estruturais, concordantes com a disposição sub-horizontal das camadas. Nas regiões de escudo pode-se identificar algumas áreas de relevo suave, porém de extensão restrita. A grande extensão das superfícies estruturais associadas às bacias sedimentares cretáceas parece ter levado vários autores à falsa impressão de continuidade pretérita dessas superfícies, hoje isoladas. Este fato, somado às inferências de \"superfícies cimeiras\" com base no aparente nivelamento de topos de morros em terrenos cristalinos, também levou diversos autores a proporem a extensão de superfícies de aplainamento até a região próxima da costa Atlântica. A integração entre dados morfométricos, termocronológicos e geofísicos não suporta a validade do uso de superfícies aplainadas em correla~ções estratigráficas de âmbito regional. Entretanto, admite-se a aplicabilidade, em escala local, da correlação entre níveis morfológicos distintos. As técnicas morfométricas empregadas neste estudo se mostram válidas não apenas para o estudo da superfíciie topográfica, mas também de superfícies soterradas e de sua paleogeografia. A disponibilidade de modelos de elevação gerados por sensoriamento remoto permite o emprego da análise digital de terreno em escalas local a global, com amplo leque de aplicações , não apenas no estudo das formas de relevo terrestres, mas também de outros corpos planetários.Digital terrain analysis, or geomorphometry, is the practice of ground-surface quantification, through the application of techniques in Earth sciences, mathematics, engineering and computer science. The Shuttle Radar Topography Mission (SRTM) digital elevation model (DEM) is currently the only near-global data available to perform local to regional-scale landform analysis. The production of a DEM using a single technique, radar interferometry, means that there is consistency in quality, availability and scale. This work focuses upon the study of landforms in central-eastern Brazil by means of morphometric characterization of DEMs and integration between morphometric, thermochronologic and geophysical data, as well as an evaluation of the validity of use of at surfaces in regional stratigraphic correlations. Morphological profiles and aspect maps show a N-S trend of the major landforms of central-eastern Brazil, while smaller landforms have a NW-SE organization, better observed in the southeast region, but visible throughout the study area. The spatial distribution of thermochronological data in Brazil is highly heterogeneous, with samples clustered in the south-southeast and northeast regions. Data from the southeast region does not show continental break-up as the main cooling event, which is identified by the large number of samples with fission-track ages (FT) between 60 and 80 Ma and that can be seen as a regional uplift event (followed by intense denudation), given the elevation range of the samples in this time span. There is a subtle trend of older FT ages from the coast towards the interior. The trend of older FT ages as distance from the coast increases is better represented in data from the northeast region. Samples with ages around 100 Ma can be related to the continental break-up. Morphometric analyses did not allowed the identification of vast erosional planation surfaces in the study area. Areas with a very smooth topography are related to alluvial plains (São Francisco, Araguaia and Tocantins rivers), Cretaceous sedimentary basins (Chapadão Ocidental da Bahia, Chapada do Araripe, Bauru Basin) and Paleozoic basins with Cretaceous cover (Parecis Basin) where the surface follows the subhorizontal bedding. In shield regions, several low-relief areas can be identified, although they are small in extent. The large extent of low-lying surfaces associated with Cretaceous sedimentary basins has lead several authors to suggest that these { presently isolated { surfaces were continuous. This, added to inferences of \"summit levels\" based on the apparent levelling of hilltops in crystalline terrains, has also lead several authors to suggest that the planation surfaces extend close to the Atlantic shore. The integration of morphometric, thermochronologic and geophysical data does not support the validity of use of at surfaces in regional stratigraphic correlations. However, correlation between distinct morphological levels, at a local scale, is suitable. The morphometric techniques used in this study are valid not only for the analysis of topographic surfaces, but also of buried surfaces and their palaeogeography. The availability of remote sensing generated elevation data allows the application of digital terrain analysis from local to global scales, with a range of applications, not only in the study of terrestrial landforms, but also of other planetary bodies.

Full textAbstract:
A Web GIS system has a major issue of serving the map data to the client applications. Since most of the GIS services provide their geospatial data as basic image formats like PNG and JPEG, constructing those images and transferring them over the internet are costly operations. To enhance this inefficient process, various approaches are offered. Caching the responses of the requests on the client side is the most commonly implemented solution. However, this method is not adequate by itself. Besides caching the responses, predicting the next possible requests of the client and updating the cache with the responses for those requests provide a remarkable performance improvement. This procedure is called &ldquoprefetching&rdquo
. Via prefetching, caching mechanisms can be used more effectively and efficiently. This study proposes a prefetching algorithm called Retrospective Adaptive Prefetch (RAP). The algorithm is constructed over a heuristic method that takes the former actions of the user into consideration. This method reduces the user-perceived response time and improves users&rsquo
navigation efficiency. The caching mechanism developed takes the memory capacity of the client machine into consideration to adjust the cache capacity by default. Otherwise, cache size can be configured manually. RAP is compared with 4 other methods. According to the experiments, this study shows that RAP provides better performance enhancements than the other compared methods.

As the popularity of Geographic Information System (GIS) technology increases and its use extends from specialized users to the general public, tools available to users must adapt to take these changes into account. Virtual globes, such as Google Earth, are simplified GIS tools which do not include any of the data analysis and visualization capabilities of traditional GIS. However, the use of these applications can be extended by shifting the GIS functionality out of the application and into KML, through the dynamic manipulation of KML objects, allowing for some of the functionality of GIS to be reintroduced. Because KML objects include coordinates, they can be manipulated in a way which allows georeferenced data to be visualized within virtual globes in a way that is user-accessible, allowing for GIS to be more accessible to a greater number of users.

Das Projekt OpenStreetMap als freie Wiki-Weltkarte gewinnt als Quelle von Geodaten für unter-schiedlichste Bedürfnisse innerhalb der Geowissenschaften, des Geomarketings und auch im Alltag immer mehr an Bedeutung. Die kostenlosen, von Freiwilligen einer Community gesammelten geo-graphischen Daten, sogenannte nutzergenerierte Daten, dienen heute vielen Anwendern als Daten-grundlage und stehen in der Konkurrenz zu proprietären Geodaten von kommerziellen Anbietern. Neben Straßendaten sind zahlreiche zusätzliche Daten innerhalb OpenStreetMap verfügbar. Die aktuelle Technologie des Webmapping 2.0 und die dafür zahlreich verfügbaren Open Source GIS Systeme erlauben dem Anwender eine Vielzahl von Möglichkeiten zu Bearbeitung von Geodaten. Die freie Verfügbarkeit von Daten und Software machen die Nutzung und Verarbeitung von Geoda-ten somit auch für kleinere Unternehmen und Privatnutzer bezahlbar. Die vorliegende Studienarbeit stellt ein Verfahren vor, welches es ermöglicht aus OpenStreetMap-Daten Postleitzahlgebiete zu erstellen. Postleitzahlgebiete sind für viele Bereiche der Wirtschaft sehr wichtige Planungsstrukturen. Als Datengrundlage werden OSM-Adressdaten genutzt, aus denen, unter Nutzung von Open Source GIS Software, die Postleitzahlgebiete erzeugt werden. Die Generie-rung ist dabei automatisierbar und ohne die Nutzung grafischer Benutzeroberflächen möglich. Sie liefert als Ergebnis die Postleitzahlgebiete Deutschlands. Diese werden anschließend, unter Berück-sichtigung der ISO-Normen für Geoinformation, mit einem kommerziellen Datensatz verglichen und auf ihre Nutzbarkeit für Geomarketing und andere nützliche Anwendungen hin überprüftThe OpenStreetMap project as the Free Wiki World Map as a source of gains for a wide variety of geospatial data needs within the geosciences, the geomarketing and in everyday life is becoming increasingly important. The free, a community of volunteers gathered geo-graphical data, so-called user-generated data, now serve many users as basic data and are in competition with proprietary spatial data from commercial providers. In addition to road data within OpenStreetMap numerous additional data is available. The current technology of the Web Mapping 2.0 and the many available Open Source GIS systems provide the user with a variety of options for managing spatial data. The free availability of data and software make the use and processing of geospatial data thus affordable for small businesses and home users. The current work presents a method that allows to create postcode areas from OpenStreetMap data. Postcode areas are very important planning structures for many areas of the economy. The OSM address data are used as data base, out of which the zip code areas are produced by taking advan-tage of Open Source GIS software. The creation is automated and without the use of graphical user interfaces. It provides as result the postal code areas of Germany. Taking into account the ISO stan-dards for geoinformation, the postal code areas are later compared with a commercial data set and their usability for geomarketing and other useful application is tested

Full textAbstract:
Lifelines are vital networks and it is important that those networks are still be functional after major natural disasters such as earthquakes. The goal of this study is to develop a GIS software for evaluating network reliability of lifelines under seismic hazard. In this study, GIS, statistics and facility management is used together and a GIS software module, which constructs GIS based reliability maps of lifeline networks, is developed by using geoTools. Developed GIS module imports seismic hazard and lifeline network layers in GIS formats using geoTools libraries and after creating a gridded network structure it uses a network reliability algorithm, initially developed by Yoo and Deo (1988), to calculate the upper and lower bounds of lifeline network reliability under seismic hazard. Also it can show the results in graphical form and save as shape file format. In order to validate the developed application, results are compared with a former case study of Selcuk (2000) and the results are satisfactorily close to previous study. As a result of this study, an easy to use, GIS based software module that creates GIS based reliability map of lifelines under seismic hazard was developed.

Full textAbstract:
Rapid urbanization has opened the way to congested cities such as New
Delhi, Mumbai etc. and has been very challenging for urban drainage systems.
Poorly designed urban drainage systems, congestion of the stream channel,
overcrowding, expansion of urban infrastructure without appropriate
consideration of drainage issues, increase in paved surfaces, and climatic
conditions are the major causes of these disasters. As a response of these
circumstances, flash floods occur, resulting in both ground and surface water
quality deterioration. In order to have better results, competent planning, analysis,
and design of urban drainage skills are expected. In this study, ArcGIS software
is used to simulate the urban drainage system. The rainfall data required is
gathered from Irrigation and Flood Control Department, Delhi. For a drainage
region in SAID UL AJAIB, near Saket metro station, Delhi, India, the simulation
was done to understand problems associated with inadequate urban drainage.
From the results obtained, it was seen that some parts of Sail ul Ajaib area are
frequently affected by flooding.

This thesis investigates information systems development with special regard to the area of Geographical Information Systems. It addresses the area through the investigation of the software life-cycle development model and its augmentation by the use of prototyping. Observations are made on empirical experiments conducted to assess the usefulness of the new techniques of hypertext and hypermedia and their suitability within this field of study. This investigation is complemented by a case study, the Norfolk and Suffolk Broads Authority. The Norfolk and Suffolk Broads are designated by statute with similar status to the National Parks of Great Britain, and are managed by the Norfolk and Suffolk Broads Authority. Through cooperation with the Norfolk and Suffolk Broads Authority, a prototype information system was created. This system makes use of geographical data from the Broads Authority. The development stages of this system were used to conduct experiments for this thesis. The tools and techniques used for the development of this system are described. These include a hypertext tool called FIELD (Fully Integrated Environment for Layered Development) which has been especially designed for the complete storage of all information for each stage throughout this development. The use of this tool and hypertext for the development of the geographically based information system for the Norfolk and Suffolk Broads Authority are discussed.

Para la automatización de dicha tarea, existe en el mercado una amplia variedad de software GIS, dentro de la cual destaca la oferta de ESRI. Sin embargo, los costos de implementar una solución como la ofrecida por ESRI no pueden ser asumidos por pequeñas y medianas organizaciones. De esta situación se hace cargo este trabajo. Este trabajo consistió en la construcción de un marco de desarrollo base para publicar información geográfica, el cual consta de dos elementos principales: * Un conjunto de librerías que extienden un framework de desarrollo web, para el trabajo con objetos geográficamente referenciados. * Una aplicación web, construida sobre la base del framework extendido, para generar y administrar Aplicaciones Web de Mapas. El resultado obtenido, basados en tecnologías gratuitas y de código abierto, fue validado a partir de la implementación de un caso de uso, consistente en la creación y extensión de una Aplicación Web de Mapas en un dominio específico. Se concluye que el trabajo realizado permitirá a las organizaciones de menor tamaño publicar la información geográfica de la que disponen de manera controlada, y se plantean finalmente algunas recomendaciones sobre cómo seguir extendiendo las funcionalidades del marco de desarrollo base.

Full textAbstract:
2008/2009Sebbene il patrimonio forestale italiano sia rilevante per l'ambiente e l'economia, per l'equilibrio del territorio, per la conservazione della biodiversità e del paesaggio, ogni anno è minacciato da numerosi incendi boschivi anche devastanti. Le conseguenze per l'equilibrio naturale, in caso d'incendio, sono di grossa entità ed i tempi per il recupero dell'ecosistema si attestano su periodi piuttosto lunghi. Importante è anche ricordare che l'Assemblea generale dell'ONU ha dichiarato il 2011 Anno Internazionale delle Foreste, al fine di aumentare la consapevolezza sulla gestione sostenibile, la conservazione e lo sviluppo sostenibile di tutte le tipologie di foreste. Pertanto, vista l'entità e la frequenza con cui viene colpita l'area carsica dagli incendi boschivi, è stato sviluppato un lavoro per lo studio ed il monitoraggio degli incendi boschivi nell'area carsica appunto, impiegando software FOSS (Free and Open Source Software) come i GIS GRASS, QuantumGIS, gvSIG Desktop e Mobile, il pacchetto Sextante (integrato in gvSIG) ed il software statistico R Project. Un primo approccio è stato effettuato come studio in collaborazione con l’Ispettorato Ripartimentale Foreste di Trieste e Gorizia e con l'Ente Forestale Sloveno di Sežana (ZGS), su un sito test a cavallo del confine italo-sloveno colpito nell'estate 2003 da un rilevante incendio. Aree della stessa tipologia vegetale incendiate e non sono state monitorate mediante dati satellitari Landsat (2003-2009) allo scopo di confrontare il ripristino della copertura vegetale dell’area incendiata rispetto a quella rimasta inalterata. Attraverso gli indici di vegetazione NDVI e NDWI e dati meteorologici, si è evidenziato come nelle aree incendiate vi sia un trend complessivo di ripresa nell’arco di 6 anni. In secondo luogo, avendo appurato che effettivamente gli incendi boschivi vengono influenzati da numerosi fattori, tra cui le componenti ambientali, sono state approfondite le dinamiche che possono interagire con lo sviluppo degli incendi boschivi per tutta l'area carsica. Una tematica affrontata mediante una correlazione tra le serie storiche degli incendi e le componenti ambientali del territorio. Per il periodo 1995-2009, dati input come catasto incendi, dati meteorologici, parametri morfologici del terreno, Corine Land Cover e dati litologici, sono stati ricavati valori medi d'incidenza degli incendi boschivi suddivisi per categorie di parametri. Le corrispondenze tra fattori sono risultate da un' Analisi delle Componenti Principali (PCA) con R, che ha permesso di rappresentare un insieme di dati in un numero ridotto di dimensioni, evidenziando appunto delle relazioni effettive tra l'incidenza degli incendi e le caratteristiche del territorio. Un'ulteriore implementazione d'indagine ha riguardato la predisposizione del modello MultiGIS-R per la produzione di una mappa dell'incendiosità dell'area carsica. In questo contesto sono stati impiegati anche gli strumenti software FOSS che permettono l'interconnessione ed integrazione tra diversi programmi. Come elementi del sistema sono stati considerati innanzitutto i dati d'analisi del terreno (DTM 5 m, slope, aspect), le ortofoto della Regione FVG (visibile ed infrarosso), immagini satellitari Landsat, un'accurata Carta d'uso del suolo (gruppo botanico del Prof. Poldini), a cui si sono aggiunte delle elaborazioni come la carta dell'assolazione, la carta dei parametri morfometrici del terreno, aree d'individuamento delle pinete. Tali configurazioni di lavoro hanno evidenziato, oltre alle caratteristiche professionali, intuitive e versatili degli applicativi FOSS, un'efficacia nell'applicazione ad ambiti come la gestione ed il monitoraggio ambientale, elaborazione di mappe di rischio o la pianificazione territoriale, unitamente ai vantaggi apportati dalla disponibilità delle comunità di supporto (ambienti multidisciplinari e multipiattaforma) e dalla comunicazione diretta con gli sviluppatori software.

Full textAbstract:
Geographic features change over time, this change being the result of some kind of event or occurrence. It has been a research challenge to represent this data in a manner that reflects human perception. Most database systems used in geographic information systems (GIS) are relational, and change is either captured by exhaustively storing all versions of data, or updates replace previous versions. This stems from the inherent diffculty of modelling geographic objects in relational tables. This diffculty is compounded when the necessary time dimension is introduced to model how those objects evolve. There is little doubt that the object-oriented (OO) paradigm holds signi cant advantages over the relational model when it comes to modelling real-world entities and spatial data, and it is argued that this contention is particularly true when it comes to spatio-temporal data. This thesis describes an object-oriented approach to the design of a conceptual model for representing spatio-temporal geographic data, called the Feature Evolution Model (FEM), based on states and events. The model was used to implement a spatio-temporal database management system in Oracle Spatial, and an interface prototype is described that was used to evaluate the system by enabling querying and visualisation.

Ingeniera Civil en ComputaciónUnholster es una empresa que se dedica al desarrollo de software a medida para clientes en distintos rubros, con énfasis en el uso y análisis de datos. Dentro de sus proyectos internos, existe uno que consiste en visualizar datos geográficos interesantes, como, por ejemplo, el padrón electoral chileno, con el objetivo de descubrir patrones o relaciones en los datos. Estas visualizaciones muestran la concentración de puntos geográficos en las distintas calles de un área de interés, y se destacan conjuntos de calles con un alto número puntos. Sin embargo, el proceso para generar estos mapas es lento, con muchas etapas ejecutadas en forma manual, lo que hace poco viable la generación de nuevas visualizaciones, u ofrecer este sistema como un servicio. En este trabajo de título se propone crear un sistema que automatice la creación de estas visualizaciones, y que además disminuya el tiempo de generación. Además, este sistema tendrá una interfaz web que permita a distintos usuarios subir sus propios conjuntos de datos a visualizar, dando la posibilidad a que esta plataforma sea ofrecida como un servicio de parte de Unholster a sus clientes. Para esto, primero se estudió el proceso manual de generación de visualizaciones, identificando las distintas etapas y las oportunidades de mejora. Con esta información se diseñó un nuevo proceso que permite acelerar las operaciones a realizar, basándose en un modelo de datos que separa las calles y manzanas de los datos que se visualizarán. Además se introdujeron mejoras, como acotar el número de objetos que participan en las operaciones que realiza el sistema. Se establecieron las acciones que los usuarios pueden realizar en el sistema, y se definió una interfaz web para que la interacción sea simple y amigable. Una vez definido el nuevo proceso y modelo de datos, se implementó una aplicación que expone una API y una interfaz web al usuario, y que implementa las operaciones descritas en este trabajo basándose en el modelo de datos planteado. Así, el sistema es capaz de generar visualizaciones para distintos tipos de datos geográficos, con una mínima participación de los usuarios y alcanzando los objetivos de tiempo planteados. Tanto el proceso como el sistema fueron validados por los directores de Unholster, quienes se mostraron satisfechos al ver que la aplicación cumple con los objetivos y los requisitos de usabilidad y tiempo de ejecución. Finalmente, este trabajo representa un primer prototipo a lo que se espera sea un nuevo producto dentro de la empresa. Ahora generar visualizaciones de mapas es un proceso rápido y mayormente automático, por lo que puede ser ofrecido a clientes que quieran explorar y analizar sus datos geográficos en forma visual, abriendo una nueva oportunidad de negocio para Unholster.

Full textAbstract:
An emerging trend in GIS is the adoption of object oriented concepts for both logical and physical design phases. Extensive research has been conducted on logical design of GIS and several conceptual models have been proposed. Classical data models like the relational data model have proven to be insufficient for the conceptual modeling of spatial data. Therefore among other object oriented modeling tools, a new modeling language, Unified Modeling Language (UML) has also become a popular modeling tool in the GIS domain due to its wide acceptance in industry. In this thesis ArcInfo UML Model, which is an extension of UML and proposed by ESRI is utilized to create analysis pattern of Sanliurfa Harran Plain within the scope of GAP (In Turkish, Güneydogu Anadolu Projesi). The proposed analysis pattern mainly characterize the irrigation drainage system, social environment and irrigation management activities of the Sanliurfa Harran Plain and incorporate the interactions between, and among, features of the system. At the implementation phase ESRI'
s geodatabase model is used. This is an object relational spatial database utilizing the full functionalities of the underlying relational DBMS. This hybrid approach claims to be the most promising approach to deal with the complex data types found in GIS applications and allows the storage of spatial and non-spatial data together. Besides many advantages of geodatabase, ability to implement it in a multi-user environment is the most remarkable one. In this thesis both the personal and multi-user approaches, in which the underlying DBMSs are MS access and Oracle, are tested. The multi-user geodatabase is built in three-tier architecture with ESRI'
s ArcSDE (Spatial Database Engine) as the middleware.

Full textAbstract:
The emergency services in neighboring Jämtland, Sweden and Nord-Sør Trøndelag, Norway have identified a need to share data across department, municipality and country borders. A project is started to evaluate the possibility of sharing information through a common Web Geographic Information System (GIS). The data about resources at the various departments suffers from a high level of heterogeneity, fragmentation and protocol incompatibility. The Open Geo-Spatial Consortium (OGC) issue Web standards to harmonize the processing of geo-spatial data and promote interoperability between GIS systems. A test model based on the Thin Thread Model, emulating a potential final solution, is built to evaluate the usability of these Web standards in the situation. Successful test cases including CRUD operations and relatively smooth swapping of layer modules show that using well-established standards can be beneficial. A proposed architecture extending the test model presents the idea of a centralized proxy node and a meta data catalog. The study highlights the issue of responsibility and question of which authority should maintain centralized nodes. In order to successfully implement a Web portal, the project participants must from a technical point of view investigate how to access all desired data, agree on protocols for communication and ensure that each owner of data provides an API in agreement with the protocol. The OGC Web standards are proven a good option and focal point.

Full textAbstract:
Several hundred thousand miles of energy pipelines span the whole of North America -- responsible for carrying the natural gas and liquid petroleum that power the continent's homes and economies. These pipelines, so crucial to everyday goings-on, are closely monitored by various operating companies to ensure they perform safely and smoothly.
Happenings like earthquakes, erosion, and extreme weather, however -- and human factors like vehicle traffic and construction -- all pose threats to pipeline integrity. As such, there is a tremendous need to measure and indicate useful, actionable data for each region of interest, and operators often use computer-based decision support systems (DSS) to analyze and allocate resources for active and potential hazards.
We designed and implemented a geospatial data service, REST API for Pipeline Integrity Data (RAPID) to improve the amount and quality of data available to DSS. More specifically, RAPID -- built with a spatial database and the Django web framework -- allows third-party software to manage and query an arbitrary number of geographic data sources through one centralized REST API.
Here, we focus on the process and peculiarities of creating RAPID's model and query interface for pipeline integrity management; this contribution describes the design, implementation, and validation of that model, which builds on existing geospatial standards.

Full textAbstract:
We now live in a society where communicating is done mostly through computer-technology based mediums. In Swedish municipal infrastructure a lot of the communication-data consists of geospatial data-collections. This data is generated with Geographical Information Systems (GIS) which usage in Sweden has increased rapidly. This has lead to a competition between developers in designing their systems for a wider user-base. A transition between designs that has its focus on a small target group and designs intended for a wide range of different users puts the developers in a challenge where usability is one of the big concerns. In this thesis we, have adopted a qualitative research approach with contextual observations and usability testing, in order to identify the crucial usability concerns when designing GIS for a wider user-base. Results show that the most crucial usability concerns are related to system feedback and the GIS not being compatible with other GIS data formats. The research has been concentrated within municipalities in Sweden and results presented in this thesis are rough, but true indications. More research is needed to get detailed accuracy of the usability concerns. We hope that this thesis will aid developers of GIS in their design-phase and to be part of a foundation to future GIS-standards.

Middle East Technical University (METU) campus has such an extensive area that reaching the necessary information which affects campus life, such as the locations of the buildings, classrooms, computer labs, and etc. may be very difficult for anyone who does not know the campus well, and even for a student, personnel or a graduate who had a long time in the campus. An interactive campus map and a database structure related to this map which can be accessed by multiple types of users on the Internet can display this information with its geographical locations, and will reduce the "difficulty for reaching information"
widely. For this purpose, data of METU were collected from various sources, edited, organized, and inserted into data tables. An interactive campus map displaying the locations of the physical structures and facilities in the campus was created in Scalable Vector Grapics (SVG) standard, and published on the Internet. By JavaScript functions, the map can be browsed with map navigation tools, including zoom in, zoom out, move and information buttons, and layers control. There is a search section on the user interface, which allows users make queries to find building and classroom names, and list the buildings and facilities according to their usage and category types. Data are stored in PostgreSQL database, transmitted through PHP scripts, and can be edited by authorized users through the specialized web interfaces. Lastly, web-based implementation of the application is entirely based on open-source standards.

Oracle DBMS software was also analyzed to prove that it has all necessary components for spatial data manipulation. After summarizing analysis results we offer new GIS solution, which allows rendering enterprise data on the map in dynamic way without knowing enterprise data structure and minimizing programmer work. To implement a dynamic GIS conception a new dynamic GIS architecture and the missing component design for representing business data in a map are created. To ensure dynamic integration and simple usage of component, dynamic integration component functionality is based on business rules conception. To demonstrate dynamic enterprise and spatial data integration on the map, dynamic GIS architecture was implemented using Oracle software by configuring data integration component to use Oracle mapViewer. For dynamic GIS testing, test interface was created with an ability to write business rules directly in web page and see the integration results. Existing spatial data was imported into Oracle DB and some spatial data for testing purposes was created manually.

Context: Smartphone is gaining popularity due to its feasible mobility, computing capacity and efficient energy. Emails, text messaging, navigation and visualizing geo-spatial data through browsers are common features of smartphone. Display of geo-spatial data is collected in computing format and made publically available. Therefore the need of usability evaluation becomes important due to its increasing demand. Identifying usability requirements are important as conventional functional requirements in software engineering. Non-functional usability requirements are objectives and testable using measurable metrics. Objectives: Usability evaluation plays an important role in the interaction design process as well as identifying user needs and requirements. Comparative usability requirements are identified for the evaluation of a geographical information system (Google Maps) on personal computer (Laptop) and smartphone (iPhone). Methods: ISO 9241-11 guide on usability is used as an input model for identifying and specifying usability level of Google Maps on both personal computer and smartphone for intended output. Authors set target value for usability requirements of tasks and questionnaire on each device, such as acceptability level of tasks completion, rate of efficiency and participant’s agreement of each measure through ISO 9241-11 respectively. The usability test is conducted using Co-discovery technique on six pairs of graduate students. Interviews are conducted for validation of test results and questionnaires are distributed to get feedback from participants. Results: The non-functional usability requirements were tested and used five metrics measured on user performance and satisfaction. Through usability test, the acceptability level of tasks completion and rate of efficiency was matched on personal computer but did not match on iPhone. Through questionnaire, both the devices did not match participant’s agreement of each measure but only effectiveness matched on personal computer. Usability test, interview and questionnaire feedback are included in the results. Conclusions: The authors provided suggestions based on test results and identified usability issues for the improvement of Google Maps on personal computer and iPhone.+46 (0) 76 55 44 637

Full textAbstract:
Visibility analysis is an important GIS tool that is used in a diverse array of disciplines ranging from earth sciences to telecommunications. Multi-visibility, as a cumulative type of visibility, combines many point-to-point results into a multi-value array. Points, lines, or areas can be used as sources
or targetsand the combined values can be calculated in both ways. Through multi-visibility, a special 2.5D visibility value surface can be constructed over a digital elevation model. The effectiveness of multi-visibility can be increased with weighted target zones. Other types of weighting criteria can be defined, such as distance and angle. Open source GIS tools offer a limited amount of support for that type of multivisibility analysis. In this study, a weighted multi-visibility methodology has been developed which accepts a path as the source. The path can have a specific direction to account for moving subjects that have a specific view angle based on their direction. A software tool has been developed to apply the methodology in a practical and automated way. The tool was written in Python programming language and can be run as a plugin to the open source Quantum GIS software. The proposed weighted multi-analysis methodology and its software tool can be used to assess the quality of visibility through the generation of value surfaces and calculation of a combined quantitative visibility value for the full path.

Spatial Data Analysis (SDA) is relatively narrower and constitutes one of the areas of Spatial Analysis. Geographic Information System (GIS) offers a potentially valuable platform for supporting SDA techniques. Integration of SDA with GIS helps SDA to benefit from the data input, storage, retrieval, data manipulation and display capabilities of GIS. Also, GIS can benefit from SDA techniques in which the integration of these techniques can increase the analysis capabilities of GIS. This integration serves for disseminating and facilitating improved understanding of spatial phenomena.
How SDA techniques should be integrated with GIS arise the coupling problem. The complete integration of SDA techniques in GIS can be applied without the support of GIS vendor when the free/libre and open source software (FLOSS) development methodology is properly followed. This approach causes to interpret the coupling problem in a new way. This thesis aims to develop a fully coupled SDA with GIS in FLOSS environment. A fully coupled SDA in free GIS software as FLOSS system is developed by writing nearly 13,000 line Python code in 2.5 years. Usage of this system has reached to nearly 1600 unique visitors, 3000 visits and 8600 page views in two years.
As the current status of development in GIS is considered, it is unlikely in commercial market to have full coupled SDA techniques in GIS software. However, it is expected to have more SDA developments in proprietary GIS software in the near future as there is an increasing trend for requesting more sophisticated SDA tools.

Full textAbstract:
I GIS (Geographic Information System) sono sistemi informatizzati per l'acquisizione, la memorizzazione, il controllo, l'integrazione, l'elaborazione e la rappresentazione di dati che sono spazialmente riferiti alla superficie terrestre. Nei Paesi in via di sviluppo questi strumenti vengono impiegati oltre che nelle discipline tecniche e naturali in quelle umanistiche (archeologia, ecologia umana, studi linguistici, ecc), nelle scienze sociali ( geografia umana ed economica, economia, ecc. ) e in medicina (medicina sociale e professionale, epidemiologia ecc.). Le applicazioni vanno dall’ inventario delle risorse naturali al monitoraggio attraverso la pianificazione territoriale, dalla programmazione economica e sociale alla gestione delle aree protette per arrivare alla protezione del patrimonio culturale e al turismo. Il mercato del software ha sviluppo negli ultimi anni un numero elevato di applicativi GIS. Il fenomeno della crescita nella disponibilità di software GIS non è stata accompagnata da un corrispondente aumento della conoscenza teorica e della competenza specifica necessaria. La mancanza di decisioni consapevoli sulle modalità di registrazione dei dati prese fin all’inizio, unita ad incomprensione delle capacità e delle limitazioni dei software, spesso rischiano di palesarsi a progetto finito.
La tesi sviluppa delle linee guida che consentono di controllare le varie fasi della progettazione GIS considerando i vincoli specifici del contesto di applicazione e del progetto specifico. Inoltre si propone un modello di selezione di un software GIS che utilizza sia parametri qualitativi che quantitativi.

This thesis was designed and built to test a new system of hardware-software combined study for the control and management of geological risk arising from mud flow landslides and slopes slow movements.
The various issues that arise at present in the landslide management risk are related to poor knowledge of the territory from the geological, geomorphological and specially geodynamic point of view. In risk management modern technical software and hardware very often are neglected, probably because no direct knowledge, that would allow a more advanced risk management in real time.
The latest hardware and software generation can identify, if associated with the availability of appropriate and correct data, any type of risk triggering cause arising from natural or anthropogenic factors.
This thesis focuses on the resolution of the above mentioned issues and finding detailed use not only at the civil protection level but also in the freelance profession.
In this thesis has been tested, with positive results, the Open - Source (OS) software applied to geological, geomorphological and geodynamic data collected on field in two areas; Olvera in Spain (detection area) and Oliveto Lucano in Italy (test area). OS software are indeed available and freely accessible at no cost.
The development of the project was divided into three main phases coinciding with the duration of doctorate (three years). They are: Geological and geomorphological survey (1st phase), server management versus UMPC and Open Source software (2nd phase) and two and three dimensional simulations of mud flow landslides with verify on test area (3rd phase).
More specifically, in the first year, in addition to the bibliographic collection and the choice of detection area (Olvera, Cadiz, Andalucia, Spain) and the test area (Oliveto Lucano, Matera, Basilicata, Italy) was carried out an intensive geological and geomorphological survey with the collection of all available data through the use of an Ultra Mobile Personal Computer (UMPC) above all in the Olvera. During the field work were selected and tested some of the OS software for digitization and data acquisition. Meanwhile in the laboratory was achieved on the network server, the web site, the DBMS database and the GUI of the WebGIS.
In the second year were improved techniques for survey detection through the use of UMPC and its direct connection with the server via HSDPA (High Speed Downlink Packet Access). Have also completed the selection, installation and development of other OS software needed to complete the project for the DBMS and the WebGIS area. Most important was the realization, through GIS and graphics tools chosen, geological and geomorphological maps and especially the map of susceptibility. After the realization of map of susceptibility, was performed a new detection phase on the field for a map validation.
In the third year the software development for the monitoring of movements by comparison of automatic objects placement on the territory from orthophotos or aerial photos of different years was performed and also the simulated two-and three-dimensional mud flow phenomena and slopes slow movements. All the simulations and tests carried out on landslides in the Olvera was verified on field. Even the simulation of landslides in the area of Oliveto Lucano have been tested on field.
During the three years of the PhD were produced poster, pbstract and articles. Here are the headlines: A tiicks published:

Os testes são uma atividade crucial no desenvolvimento de sistemas, pois uma boa
execução dos testes podem expor anomalias do software e estas podem ser corrigidas
ainda no processo de desenvolvimento, reduzindo custos. Esta dissertação apresenta
uma ferramenta de testes chamada SIT (Sistema de Testes) que auxiliará no teste de
Sistemas de Informações Geográficas (SIG). Os SIG são caracterizados pelo uso de
informações espaciais georreferenciadas, que podem gerar um grande número de casos
de teste complexos. As técnicas tradicionais de teste são divididas em funcionais e
estruturais. Neste trabalho, o SIT abordará os testes funcionais, focado em algumas
técnicas clássicas como o particionamento de equivalência e análise do Valor Limite.
O SIT também propõe o uso de Lógica Nebulosa como uma ferramenta que irá sugerir
um conjunto mínimo de testes a executar nos SIG, ilustrando os benefícios da
ferramenta.Testing is a very important activity that is crucial in the development of information systems because most of the software costs could be avoided if better testing was performed. This dissertation describes a tool for a Testing System named SIT (System of Testing) to support the testing performance of Geographic Information Systems (GIS). GIS have the characteristics of spatial referenced persistent data that can generate a great and complex number of test cases. The traditional approaches for designing test cases can be divided into black box (functional) testing and white box testing. At first SIT will treat only the functionality testing method focused on the classic techniques of Equivalence Partitioning and Boundary Value Analysis (BVA). SIT also proposes the use of fuzzy logic as a tool to suggest the minimal test case to be used in those GIS to illustrate the benefits of the fuzzy logics module of this tool.

Full textAbstract:
Federal agencies and their partners collect and manage large amounts of geospatial data but it is often not easily found when needed, and sometimes data is collected or purchased multiple times. In short, the best government data is not always organized and managed efficiently to support decision making in a timely and cost effective manner.
National mapping agencies, various Departments responsible for collection of different types of Geospatial data and their authorities cannot, for very long, continue to operate, as they did a few years ago like people living in an island. Leaders need to look at what is now possible that was not possible before, considering capabilities such as cloud computing, crowd sourced data collection, available Open source remotely sensed data and multi source information vital in decision-making as well as new Web-accessible services that provide, sometimes at no cost. Many of these services previously could be obtained only from local GIS experts. These authorities need to consider the available solution and gather information about new capabilities, reconsider agency missions and goals, review and revise policies, make budget and human resource for decisions, and evaluate new products, cloud services, and cloud service providers.
To do so, we need, choosing the right tools to rich the above-mentioned goals. As we know, Data collection is the most cost effective part of the mapping and establishment of a Geographic Information system. However, it is not only because of the cost for the data collection task but also because of the damages caused by the delay and the time that takes to provide the user with proper information necessary for making decision from the field up to the user’s hand. In fact, the time consumption of a project for data collection, processing, and presentation of geospatial information has more effect on the cost of a bigger project such as disaster management, construction, city planning, environment, etc. Of course, with such a pre-assumption that we provide all the necessary information from the existing sources directed to user’s computer.
The best description for a good GIS project optimization or improvement is finding a methodology to reduce the time and cost, and increase data and service quality (meaning; Accuracy, updateness, completeness, consistency, suitability, information content, integrity, integration capability, and fitness for use as well as user’s specific needs and conditions that must be addressed with a special attention).
Every one of the above-mentioned issues must be addressed individually and at the same time, the whole solution must be provided in a global manner considering all the criteria.
In this thesis at first, we will discuss about the problem we are facing and what is needed to be done as establishment of National Spatial Data Infra-Structure (NSDI), the definition and related components. Then after, we will be looking for available Open Source Software solutions to cover the whole process to manage; Data collection, Data base management system, data processing and finally data services and presentation. The first distinction among Software is whether they are, Open source and free or commercial and proprietary. It is important to note that in order to make distinction among softwares it is necessary to define a clear specification for this categorization. It is somehow very difficult to distinguish what software belongs to which class from legal point of view and therefore, makes it necessary to clarify what is meant by various terms. With reference to this concept there are 2 global distinctions then, inside each group, we distinguish another classification regarding their functionalities and applications they are made for in GIScience.
According to the outcome of the second chapter, which is the technical process for selection of suitable and reliable software according to the characteristics of the users need and required components, we will come to next chapter. In chapter 3, we elaborate in to the details of the GeoNode software as our best candidate tools to take responsibilities of those issues stated before.
In Chapter 4, we will discuss the existing Open Source Data globally available with the predefined data quality criteria (Such as theme, data content, scale, licensing, and coverage) according to the metadata statement inside the datasets by mean of bibliographic review, technical documentation and web search engines. We will discuss in chapter 5 further data quality concepts and consequently define sets of protocol for evaluation of all datasets according to the tasks that a mapping organization in general, needed to be responsible to the probable users in different disciplines such as; Reconnaissance, City Planning, Topographic mapping, Transportation, Environment control, disaster management and etc…
In Chapter 6, all the data quality assessment and protocols will be implemented into the pre-filtered, proposed datasets. In the final scores and ranking result, each datasets will have a value corresponding to their quality according to the sets of rules that are defined in previous chapter.
In last steps, there will be a vector of weight that is derived from the questions that has to be answered by user with reference to the project in hand in order to finalize the most appropriate selection of Free and Open Source Data. This Data quality preference has to be defined by identifying a set of weight vector, and then they have to be applied to the quality matrix in order to get a final quality scores and ranking. At the end of this chapter there will be a section presenting data sets utilization in various projects such as “ Early Impact Analysis” as well as “Extreme Rainfall Detection System (ERDS)- version 2” performed by ITHACA.
Finally, in conclusion, the important criteria, as well as future trend in GIS software are discussed and at the end recommendations will be presented.

Full textAbstract:
A utilização de modelos conceituais para o processo de desenvolvimento de aplicações em geral é de fundamental importância. Aplicações geográficas precisam gerenciar objetos espaciais, juntamente com não-espaciais, bem como objetos temporais. Este fator vem exigindo considerável esforço no desenvolvimento de aplicações geográficas. A complexidade na manipulação dessas informações temporais vem demandando esforços ainda maiores na modelagem conceitual, para que estas realmente permitam a representação dos fenômenos naturais e suas variações no tempo. Modelos de dados geográficos, incluindo o modelo de dados para aplicações geográficas OMT-G, propõem algumas primitivas para a criação de esquemas estáticos, dinâmicos e de apresentação utilizados para modelagem de aplicações geográficas. Apesar da sua expressividade, este modelo ainda não tem recursos para representação de aspectos temporais de dados geográficos. Este trabalho propõe e exemplifica um conjunto de primitivas temporais, projetadas para complementar e estender o OMT-G. O trabalho também inclui o desenvolvimento de uma ferramenta de modelagem, chamada Geo-Temporal, que oferece suporte ao desenvolvimento de aplicações espaço-temporais usando a extensão temporal criada para o OMT-G.
