Abstract:
We propose to advance the scientific understanding through applications of geospatial service platforms, which can help students and researchers investigate various scientific problems in a Web-based environment with online tools and services. The platform also offers capabilities for sharing data, algorithm, and problem-solving knowledge. To fulfil this goal, the paper introduces a new course, named "Geospatial Service Platform for Education and Research", to be held in the ISPRS summer school in May 2014 at Wuhan University, China. The course will share cutting-edge achievements of a geospatial service platform with students from different countries, and train them with online tools from the platform for geospatial data processing and scientific research. The content of the course includes the basic concepts of geospatial Web services, service-oriented architecture, geoprocessing modelling and chaining, and problem-solving using geospatial services. In particular, the course will offer a geospatial service platform for handson practice. There will be three kinds of exercises in the course: geoprocessing algorithm sharing through service development, geoprocessing modelling through service chaining, and online geospatial analysis using geospatial services. Students can choose one of them, depending on their interests and background. Existing geoprocessing services from OpenRS and GeoPW will be introduced. The summer course offers two service chaining tools, GeoChaining and GeoJModelBuilder, as instances to explain specifically the method for building service chains in view of different demands. After this course, students can learn how to use online service platforms for geospatial resource sharing and problem-solving.

Abstract:
Geoprocessing operations offered via web services provide the means for building complex web-based geospatial applications. Often, certain postconditions such as the spatial reference system, bounding box, schema or quality that hold on the output dataset after the execution of a geoprocessing service are determined and derived from the properties of the inputs passed to the service. Further, geoprocesses often hold preconditions that relate to more than one input, such as the requirement that all inputs must have the same schema. Within current process descriptions for geoprocessing operations, such conditions which we call cross-parameter conditions, can not be explicitly specified. In this paper, the author gives an approach to formalize such cross input-output and cross input parameter conditions in a rule-based language. Further, the author proposes an algorithm for deriving pre- and postconditions for a service composition or workflow out of the pre- and postconditions of the services involved, allowing a more automated handling of workflows in general.

Abstract:
With the advancements in GIS technologies and extensive use of OGC Web Services, geospatial resources and services are becoming progressively copious and convenient over the network. The application of OGC WCS (Web Coverage Service) and WFS (Web Feature Service) standards for geospatial raster and vector data has resulted in an opulent pool of interoperable geodata resources waiting to be used for analytical or modelling purposes. The issue of availing geospatial data processing with the aid of standardised web services was attended to by the OGC WPS (Web Processing Service) 1.0.0 specifications (Schut, 2007) which elucidate WPS as a standard interface which serves for the promulgation of geo-processes and consumption of those processes by the clients. This paper outlines the design and implementation of a geo-processing tool utilizing coverage data. The geo-process selected for application is the calculation of Normalized Difference Vegetative Index (NDVI), one of the globally used indices for vegetation cover monitoring. The system is realised using the Geospatial Data Abstraction Library (GDAL) and Python. The tool accesses the WCS server using the parameters defined in the XML request. The geo-process upon execution, performs the computations over the coverage data and generates the NDVI output. Since open source technology and standards are being used more often, especially in the field of scientific research, so our implementation is also built by using open source tools only.

Abstract:
Server-side processing is principal for most of the current Web-based geospatial data processing tools. However, in some cases the client-side geoprocessing may be more convenient and acceptable. This study is dedicated to the development of methodology and techniques of Web services elaboration, which allow the client-side geoprocessing also. The practical objectives of the research are focused on the remote sensing data processing, which are one of the most resource-intensive data types. <br><br> The idea underlying the study is to propose such geoprocessing Web service schema that will be compatible with the current serveroriented Open Geospatial Consortium standard (OGC WPS standard), and additionally will allow to run the processing on the client, transmitting processing tool (executable code) over the network instead of the data. At the same time, the unity of executable code must be preserved, and the transmitted code should be the same to that is used for server-side processing. This unity should provide unconditional identity of the processing results that performed using of any schema. The appropriate services are pointed by the authors as a Hybrid Geoprocessing Web Services (HGWSs). <br><br> The common approaches to architecture and structure of the HGWSs are proposed at the current stage as like as a number of service prototypes. For the testing of selected approaches, the geoportal prototype was implemented, which provides access to created HGWS. Further works are conducted on the formalization of platform independent HGWSs implementation techniques, and on the approaches to conceptualization of theirs safe use and chaining possibilities. <br><br> The proposed schema of HGWSs implementation could become one of the possible solutions for the distributed systems, assuming that the processing servers could play the role of the clients connecting to the service supply server. <br><br> The study was partially supported by Russian Foundation for Basic Research (RFBR), research project No. 13-05-12079 ofi_m.

Abstract:
Remotely sensed imagery-based change detection is an effective approach for identifying land cover change information. A large number of change detection algorithms have been developed that satisfy different requirements. However, most change detection algorithms have been developed using desktop-based software in offline environments; thus, it is increasingly difficult for common end-users, who have limited remote sensing experience and geographic information system (GIS) skills, to perform appropriate change detection tasks. To address this challenge, this paper proposes an online geoprocessing system for supporting intelligent land cover change detection (OGS-LCCD). This system leverages web service encapsulation technology and an automatic service composition approach to dynamically generate a change detection service chain. First, a service encapsulation strategy is proposed with an execution body encapsulation and service semantics description. Then, a constraint rule-based service composition method is proposed to chain several web services into a flexible change detection workflow. Finally, the design and implementation of the OGS-LCCD are elaborated. A step-by-step walk-through example for a web-based change detection task is presented using this system. The experimental results demonstrate the effectiveness and applicability of the prototype system.

Abstract:
Abstract. Sharing and management of geospatial data among different communities and users is a challenge which is suitably addressed by Spatial Data Infrastructure (SDI). SDI helps people in the discovery, editing, processing and visualization of spatial data. The user can download the data from SDI and process it using the local resources. However, large volume and heterogeneity of data make this processing difficult at the client end. This problem can be resolved by orchestrating the Web Processing Service (WPS) with SDI. WPS is a service interface through which geoprocessing can be done over the internet. In this paper, a WPS enabled SDI framework with OGC compliant services is conceptualized and developed. It is based on the three tier client server architecture. OGC services are provided through GeoServer. WPS extension of GeoServer is used to perform geospatial data processing and analysis. The developed framework is utilized to create a public health SDI prototype using Open Source Software (OSS). The integration of WPS with SDI demonstrates how the various data analysis operations of WPS can be performed over the web on distributed data sources provided by SDI.

Abstract:
Many of the ongoing activities towards establishing SDI on a regional, national, and international level are focused on data sharing and dissemination. Next to data access and visualisation, data processing is a third important pillar of GIS which can generate new insights by creating derived data or conducting computational analyses on original data sets. Within today’s largely data-centric SDI, two major challenges were identified that stand in the way of ubiquitous geoprocessing: The ability to use and exchange implementations of geoprocessing functions as freely as geographic data and the ability to describe, communicate and catalogue existing functionality on the Web. This thesis evaluates the moving code approach as an alternative to client–server processing in a distributed SDI. While classical client–server configurations move pieces of data between remote processing services, data services, and clients over the network, moving code setups consider the transfer of portable software components to the location of data or the location of computing resources. To exchange implementations of geoprocessing functions at a larger scale, a Web based code sharing architecture is proposed. For improved descriptions of geoprocessing functions, WPS process descriptions are suggested as an interface description language. They are enhanced by a hierarchical profiling approach that permits different levels of granularity in the functional descriptions.

Abstract:
Numeric groundwater modeling techniques can assist water resources regulators pursuing prudent and foresightful aquifer management decisions. Unfortunately, the amount of time and professional expertise required to wield modern groundwater models often exceeds the resources of regulating agencies – even for simple modeling tasks that are repetitive in nature. In an effort to increase the accessibility of groundwater modeling resources, a server-based automated well permitting decision support system was designed. The prototype system allows a user to 1) input properties for any number of candidate wells, 2) execute an associated MOFLOW model, and 3) view relevant results of the simulation on a map such as drawdown contours and regions of decreased spring flow. The system extends the existing concept of automated well permitting geoprocessing, which involves customizable tools built with ArcGIS and Arc Hydro Groundwater geoprocessing components, by moving the geoprocessing tool to a server and creating an interactive web interface built with the Google Earth plug-in. Several strategies to initiate the server-based geoprocessing tool were considered, with and without ArcGIS Server software. A realistic case study was included to demonstrate the system in action. Such server-based automated decision support systems have promising potential to increase the accessibility of groundwater models, facilitating professional management of crucial water resources.

Abstract:
O município de Ribeirão Preto - SP, disponibiliza atenção pré-hospitalar pública através do Serviço de Atendimento Móvel de Urgência (SAMU) e de forma pioneira realiza teletriagem dos chamados de urgência em sua Central de Regulação. Assim, considerando que a teletriagem primária é um complexo método utilizado para garantir segurança, agilidade e eficácia às solicitações de socorro, apresentou-se esta proposta de investigação cujo objetivo foi verificar a aplicação da avaliação multifatorial do grau de urgência, através do mapeamento das teletriagens realizadas pela Central de Regulação do SAMU na cidade de Ribeirão Preto - SP em 2014. Neste sentido, o presente estudo se caracteriza como de abordagem quantitativa, modelo não experimental, retrospectivo, correlacional descritivo e de corte transversal, onde foram analisadas teletriagens primárias(n =2100) realizadas pela Central de Regulação do SAMU em 2014 e foi desenvolvido em quatro etapas: a primeira com uma revisão integrativa da literatura com 21 estudos primários e as demais com o interesse de descrever através do geoprocessamento a análise relacional entre as teletriagens pré-hospitalares da amostra e os fatores etiológicos, que justificam seu arranjo espacial, os casos selecionados foram submetidos a avaliação multifatorial do grau de urgência para posteriormente comparar com as distribuições espaciais encontradas, apresentando coeficiente Kappa = -0,0538. Ao final, houve comparação entre as diferentes configurações espaciais disponíveis e comprovou-se que não há evidencias da utilização da avaliação multifatorial do grau de urgência, nas amostras selecionadas para esta investigação, de teletriagens primárias do SAMU de Ribeirão Preto - SP em 2014, com base no raciocínio estatístico adotado e sob a ótica do geoprocessamento. Com isso, este estudo contribui para o monitoramento das triagens e, consequentemente, favorece o raciocínio dos fluxos do sistema, propondo o realojamento de unidades móveis de atendimento, a criação de mais equipes de suporte avançado, o engajamento em pesquisas de delineamento metodológico para desenvolver protocolos específicos para teletriagem pré-hospitalar no Brasil e tecnologias que apoiem e facilitem todo o processo
The city of Ribeirão Preto in SP, offers public pre-hospital care through the Mobile Emergency Service (SAMU) and a pioneer performs teletriage of so-called urgency in his Central regulation. Thus, considering that the primary teletriaging is a complex method to ensure safety, speed and efficiency to rescue requests, we presented this research proposal aimed to verify the application of multifactorial assessment of the degree of urgency, by mapping the teletriage made by SAMU Regulation Center in Ribeirão Preto - SP in 2014. in this sense, the present study is characterized as a quantitative approach, not experimental, retrospective design, descriptive correlational and cross-sectional, where primary teletriage were analyzed (n = 2100) conducted by the SAMU Regulation Center in 2014 and was developed in four stages: the first with an integrative literature review 21 primary studies and the other in the interest of describing through geoprocessing relational analysis between pre teletriage pre-hospital sample and etiological factors which justify their spatial arrangement; the selected cases were submitted to multifactorial assessment of the degree of urgency to later compare the spatial distributions found, with Kappa = - 0.0538 coefficient. At the end, there was a comparison between the different spatial configurations available and it was shown that there is no evidence of use of the multifactorial assessment of the degree of urgency, in the samples selected for this research, primary teletriagens SAMU of Ribeirão Preto - SP in 2014, with adopted based on statistical reasoning and from the perspective of geoprocessing. Therefore, this study contributes to the monitoring of trials and consequently favors the reasoning of system flows, proposing the relocation of mobile service units, the creation of more advanced support teams, engaging in methodological design of research to develop specific protocols for pre-hospital telescreening in Brazil and technologies that support and facilitate the process

Abstract:
Com o advento da Internet, novas tecnologias de Geoprocessamento têm sido criadas para tratar, trocar, disponibilizar e acessar informações e dados espaciais como as Infraestruturas de Dados Espaciais, os Geobrowsers e os Serviços de Informações Geográficas. O número de aplicações que lida com atributos espaciais não somente cresceu como também se diversificou, no entanto problemas de interoperabilidade semântica ainda limitam a evolução nessa área. Ontologias formalizam o conhecimento necessário para organizar e permitir o uso de dados de diferentes fontes, pois são modelos de referência robustos devido à sua expressividade e capacidade de serem compartilhados pela internet. Nesta tese, ontologias foram desenvolvidas para aumentar a interoperabilidade semântica em sistemas de apoio à logística humanitária que utilizam serviços de informações geográficas. A aplicação de logística humanitária estudada foi a operação de bancos de alimentos. O conhecimento relativo aos processos logísticos, problemas logísticos de bancos de alimentos e serviços de informações geográficas úteis para os métodos de solução desses problemas foram formalizados em uma rede de ontologias. O número de serviços de informações geográficas disponíveis ainda é pequeno, mas a composição de serviços de informações geográficas em cadeias, formando novos serviços, abre uma perspectiva para que operações espaciais, não fiquem mais restritas às soluções proprietárias e possam ser melhor exploradas. As ontologias propostas neste trabalho podem ser usadas como base para o desenvolvimento de sistemas em que serviços de informações geográficas podem ser acoplados, na medida em que forem sendo disponibilizados.
With the advent of Internet, new technologies from GIS field have been created to access and exchange spatial data and information, such as Spatial Data Infrastructures, Geobrowsers and Geographic Information Services. The number of applications dealing with spatial attributes is growing and is also diversifying. However semantic interoperability problems still limit progress in this area. Ontologies formalize the knowledge necessary to organize and allow the use of data from different sources due to its expressiveness and ability to be shared over the Internet. In this thesis, ontologies have been developed to increase the semantic interoperability of humanitarian logistics support systems that use geographic information services. The application of humanitarian logistics operation studied was the food banks operation. The knowledge on logistics processes, logistics problems of food banks and geographic information services useful for the methods for solving these problems have been formalized into a network of ontologies. The number of geographical information services available is still small, but the composition of geographic information services in chains, creating new services, opens a perspective for new methods of spatial operations, which are not limited to proprietary solutions form GIS softwares available in the market. The ontologies proposed in this thesis can be used as a basis for developing systems in which geographic information services can be coupled, as it becomes available.

Resumo: Em planejamentos ambientais as decisões sobre o futuro da paisagem dependem da compreensão de como os processos voltados ora para a preservação ora para a degradação da Natureza se deram ao longo do tempo e, conseqüentemente, como definir estratégias que conduzam à conservação ambiental. Dessa forma, necessita-se avaliar os saldos da conservação da Natureza e dos serviços ecossistêmicos dirigidos ao bem-estar humano, medidos ao longo da história em cada fração da paisagem. Porém, a literatura científica vem reforçando as deficiências metodológicas na obtenção e interpretação de tais resultados, principalmente em paisagens muito heterogêneas, onde a trama de interações apresenta-se complexa, tanto dentro de cada elemento em seu eixo vertical como entre os elementos em seu eixo horizontal. Nessa direção, avaliamos diferentes caminhos metodológicos que pudessem estrategicamente identificar unidades de planejamento que representem a heterogeneidade através das interações e fluxos bidimensionais da paisagem. Também foi realizado um pequeno ensaio sobre o valor potencial de serviços ecossistêmicos nas unidades de planejamento estabelecidas sob a abordagem de avaliação em dois eixos da paisagem. Para tanto foram construídos modelos de estrutura metodológica a partir de ferramentas estatísticas em sistemas de informação geográfica (SIG) que permitissem aplicar conceitos sobre fronteiras, mosaicos, fluxos, variabilidade e vulnerabilidade do meio natural. Os modelos foram aplicados em paisagem costeira (Ilha de São Sebastião, SP), sob um gradiente de mudanças ao longo de 50 anos. Os modelos baseados em mosaico permitiram mostrar a diversidade de interações de fronteiras entre elementos da paisagem ao longo do tempo que não seriam explicitas por modelos usuais de sobreposição. A avaliação das relações bidimensionais dos atributos da paisagem mostrou-se eficiente principalmente por expressar a heterogeneidade do interior e da borda das unidades de planejamento, além de informar sobre a variabilidade e a vulnerabilidade do meio físico. As unidades de planejamento evidenciaram um efetivo gradiente de serviços ecossistêmicos em relação a heterogeneidade e a predominância de tipos de usos, sugerindo a ocorrência de tradeoff entre essas variáveis. Apesar dos modelos apresentarem-se como um avanço no conhecimento de unidades pela heterogeneidade, eles não se mostraram de fácil aplicação e compreensão por agentes sociais, exigindo experiência técnica e considerável disponibilidade de tempo para aplicação dos métodos estatísticos
Abstract: In environmental planning, the decisions about landscape future depend on understanding how landscape processes occur over the time, sometimes facing the Nature preservation other times its degradation. Consequently, it is important to define strategies that will lead to environmental conservation.Therefore, it is necessary to evaluate the nature conservation balance and ecosystem services addressed to human well-being, measured along the history in each landscape portion. However, the scientific literature has been highlighting the methodological deficiencies in obtaining and interpreting such results, particularly in very heterogeneous landscapes, where exist complex interactions, within each element on its vertical axis and between the elements on its horizontal axis. In this way, we evaluate different methodological approaches which, strategically, identify management units that represent the heterogeneity through the two-dimensional interactions and landscape flows. In addition, we present a short essay about the potential value of ecosystem services in management units established under the two landscape axes assessment approach. We developed a methodological model that uses statistics tools and geographic information systems (GIS) taking into account the concepts of borders, mosaics, flows, variability and vulnerability of the natural environment. We applied the models in the coastal landscape of Ilha de São Sebastião-SP, under 50 years changing gradient. The models based on mosaic data showed the boundaries interactions diversity among landscape elements over time that would not be identified by usual overlap models. The two-dimensional evaluation of landscape attributes relationships has been successful mainly expressing the interior and the edge of the planning units heterogeneity, also providing information on the variability and vulnerability of the physical environment. The management units showed an effective gradient of ecosystem services related to heterogeneity and types of uses prevalence, suggesting a tradeoff among these variables. Despite the models present an advance in understanding units by heterogeneity, they were not easy to apply and understand by social agents, requiring considerable technical expertise and time availability for the implementation of statistical methods

Abstract:
In a service-oriented environment, large volumes of geospatial data and diverse geoprocessing functions are accessible as services. An intelligent mechanism is required to facilitate discovery and integration of geospatial data and services so as to enable semi-automated or automated geospatial knowledge discovery. This chapter addresses key research issues for Semantic Web enabled intelligent geoprocessing service chaining. A set of applicable solutions are described, including a common data and service environment, semantic descriptions of geoprocessing services, and a general process for intelligent generation of geoprocessing workflow. Some use cases illustrate the applicability of such solutions. A proof-of-concept prototype system is implemented and some use cases help to demonstrate the applicability of the current approach.

Abstract:
Geoprocessing operations offered via web services provide the means for building complex web-based geospatial applications. Often, certain postconditions such as the spatial reference system, bounding box, schema or quality that hold on the output dataset after the execution of a geoprocessing service are determined and derived from the properties of the inputs passed to the service. Further, geoprocesses often hold preconditions that relate to more than one input, such as the requirement that all inputs must have the same schema. Within current process descriptions for geoprocessing operations, such conditions which we call cross-parameter conditions, can not be explicitly specified. In this paper, the author gives an approach to formalize such cross input-output and cross input parameter conditions in a rule-based language. Further, the author proposes an algorithm for deriving pre- and postconditions for a service composition or workflow out of the pre- and postconditions of the services involved, allowing a more automated handling of workflows in general.

Abstract:
This paper presents an approach for enabling the commercial use of Geospatial Web Services in an on demand and ad-hoc fashion. The main goal is to go beyond classical Role-Based Access Control models in order to support ad-hoc license agreements directly in-process, without any prior offline negotiated agreements being necessary between georesource provider and geoprocessing user for on-demand access. Therefore, a general security and licensing architecture is defined as a transparent layer for Geospatial Web Services. In particular, this chapter focuses on state-of-the-art interface specifications from OGC and defines generic security extensions being applicable to all OGC standards based on OWS Common. The static model with trust relationships between the different components of the architecture in heterogeneous security domains as well the dynamic structure is studied. The presented ideas are verified by a proof-of-concept implementation following a real world scenario.
