Abstract:
Natural Disasters are natural phenomena that occur at any moment that can cause loss. Indonesia is an archipelagic country located at the meeting of four tectonic plates and volcanic belts. This condition causes Indonesia to be prone to natural disasters. Therefore, it is necessary to make a natural disaster-prone index map model minimize the impact of natural disasters. In this research, the researchers used a Polygon Thiessen method for it was one of the mapping methods to determine a natural disaster based on Indonesia's vast surface and many disasters. The BNPB and Polygon Thiessen data comparison shows that BNPB data has a low level of vulnerability of 302, a moderate level of vulnerability of 148, and a high level of vulnerability of 58. In contrast, the Thiessen polygon has a low level of vulnerability of 297, a moderate vulnerability of 158, and a high vulnerability of 59. Comparing BNPB data and the Thiessen Polygon method found five differences from 40 data in the Papua region. Suggestions for further research to create an application-based information system so that it can be accessed in real-time.

Abstract:
The average precipitation on the irrigation field can be estimated from the Meteorology Observation Stations by using spatial interpolation methods such as Thiessen polygon and isohyetal curves. However, the fact that precipitation doesn't occur homogenous in spatial scales, spatial interpolation methodologies need a large number of meteorology stations for more accurate results. In recent years, remote sensing methods have diversified to estimate precipitation. In this study, performance of the satellite-based precipitation data was assessed to determine areal precipitation over an irrigation area. This study was conducted over left bank irrigation area located in the Çukurova Plain of Turkey. Relationship between CHIRPS satellite based on monthly precipitation data and 4 meteorology stations’ data were analyzed. Determination coefficients (R2) of the stations were found between 0.64 and 0.77, for point based comparison, R2 was calculated as 0.84 with Thiessen polygon method. It is concluded that the precipitation amount in the irrigated area can be estimated as accurately as classical methods such as Thiessen polygon with satellite-based precipitation data.

Abstract:
Cellular mobile communication system divides the service area into several adjacent cells; each cell sets up a base station. In the traditional cellular representation, we always use regular hexagon to represent the cell. In the practical engineering applications and wireless network planning simulation systems, as the programming environment is complex and diverse, using the regular hexagon to represent the cellular network has limitation. This paper used Thiessen polygon and spatial analysis method to describe the cell service area with a polygon. This method intuitively displayed the relationship between the scope of service and its place with each other in space. For the Pre-construction and later optimization of wireless network planning it has a positive role.

Abstract:
Recent violence in South Sudan produced significant levels of conflict-driven migration undermining the accuracy and utility of both national and local level population forecasts commonly used in demographic estimates, public health metrics and food security proxies. This article explores the use of Thiessen Polygons and population grids (Gridded Population of the World, WorldPop and LandScan) as weights for estimating the catchment areas for settlement locations that serve large populations of internally displaced persons (IDP), in order to estimate the county-level in- and out-migration attributable to conflict-driven displacement between 2014-2015. Acknowledging IDP totals improves internal population estimates presented by global population databases. Unlike other forecasts, which produce spatially uniform increases in population, accounting for displaced population reveals that 15 percent of counties (<i>n</i> = 12) increased in population over 20 percent, and 30 percent of counties (<i>n</i> = 24) experienced zero or declining population growth, due to internal displacement and refugee out-migration. Adopting Thiessen Polygon catchment zones for internal migration estimation can be applied to other areas with United Nations IDP settlement data, such as Yemen, Somalia, and Nigeria.

Abstract:
With the development of remote sensing, the data quantity of remote sensing image is increasing tremendously. It brings a huge workload to the image geometric correction through manual ground control point (GCP) selection. GCPs automatically selected based on software is one of the effective methods to cut down manual operation. The GCPs obtained from that way is generally redundant. This paper deeply comprehends some existing methods about automatic optimization of GCP, and puts forward a new method of automatic optimization of GCP based on Thiessen Polygon to filter ground control points from the overfull ones without manual subjectivity for better accuracy. Experiments in this paper also demonstrated the relationship between the accuracy of geometric correction and the distribution of GCP. It advances the conception of single GCP’s importance value based on Thiessen Polygon. The paper gives the theory and the flow of automatic optimization of GCPs as well. It also presents an example of the application of this method. In the conclusion, this paper points out the advantages of this method .

Abstract:
The generation of high resolution canopy height model (CHM) from LiDAR makes it possible to delineate individual tree crown by means of a fully-automated method using the CHM’s curvature through its slope. The local maxima are obtained by taking the maximum raster value in a 3 m x 3 m cell. These values are assumed as tree tops and therefore considered as individual trees. Based on the assumptions, thiessen polygons were generated to serve as buffers for the canopy extent. The negative profile curvature is then measured from the slope of the CHM. The results show that the aggregated points from a negative profile curvature raster provide the most realistic crown shape. The absence of field data regarding tree crown dimensions require accurate visual assessment after the appended delineated tree crown polygon was superimposed to the hill shaded CHM.

Full text
Abstract:
Automatic methods for constructing navigation routes do not fully meet all requirements. The aim of this study was to modify the methodology for generating indoor navigation models based on the Medial Axis Transformation (MAT) algorithm. The simplified method for generating corridor axes relies on the Node-Relation Structure (NRS) methodology. The axis of the modeled structure (corridor) is then determined based on the points of the middle lines intersecting the structure (polygon). The proposed solution involves a modified approach to the segmentation of corridor space. Traditional approaches rely on algorithms for generating Triangulated Irregular Networks (TINs) by Delaunay triangulation or algorithms for generating Thiessen polygons known as Voronoi diagrams (VDs). In this study, both algorithms were used in the segmentation process. The edges of TINs intersected structures. Selected midpoints on TIN edges, which were located in the central part of the structure, were used to generate VDs. Corridor structures were segmented by polygon VDs. The identifiers or structure nodes were the midpoints on the TIN edges rather than the calculated centroids. The generated routes were not zigzag lines, and they approximated natural paths. The main advantage of the proposed solution is its simplicity, which can be attributed to the use of standard tools for processing spatial data in a geographic information system.

Full text
Abstract:
As hydrological computer modeling software continues to increase in complexity, the need for further understanding of the value of different model input datasets becomes apparent. Frequently used precipitation model input include rain gauge data and next-generation radar–based (NEXRAD) rainfall data. Rain gauge data are usually interpolated across a model domain using various methods including the Thiessen Polygon methodology, which may be data-sparse in some areas and overly data-dense in others. However, rain gauge data are generally very easy to use in hydrologic model development, often requiring little to no data processing. NEXRAD data have the potential to improve hydrologic runoff estimates due to the increased spatial resolution of the data: but has its own issues regarding accuracy, false precipitation indications, and difficulties due to data processing. Previous studies have investigated the value of NEXRAD input versus traditional rain gauge data inputs for hydrologic studies; however, results are inconclusive as to which precipitation source provides more accurate results. Limited work has been done to compare the value of these datasets at multiple spatial scales, especially in Florida, a study area dominated by low topographic drive and sub-tropical weather. In addition, little to no research has been done regarding the value of NEXRAD versus rain gauge data inputs at different rainfall return frequencies. The proposed research will utilize a hydrological rain-runoff model (HEC-HMS) of the Upper St. Johns River Basin, Florida to compare the performance of the two precipitation data input types at various watershed spatial scales and rainfall return frequencies. Statistical analysis of the hydrological model “goodness-of-fit” results will be utilized to assess the watershed scaling and rainfall frequency requirements to xii which NEXRAD data provide little to no advantage over standard rain gauges using the Thiessen Polygon method for estimating rainfall totals across a model domain.

To conduct the project, a LiDAR point cloud was used with an average density of 7 points/m², located in the city of Painel in Santa Catarina. Four subareas were selected so that only isolated trees would be considered. The laser scanning survey was conducted by the company Aeroimagem S/A from Curitiba, in January 2011 using a Leica ALS-60 system. In the fieldwork, isolated trees of A. angustifolia were measured to give the DBH, total height and 4 crown radius in the direction of the cardinal points. The fieldwork occurred in September and August 2013. To delineate the crowns, it was employed the segmentation methodology of Thiessen polygons. Each segment was measured in order to obtain the canopy diameter for each tree. For the calculation of dendrometric variables, linear regression was used to obtain the DBH as a function of the crown diameter. The total height was obtained directly from LiDAR data. Because of the seasonality between the LiDAR survey and fieldwork, it was necessary to apply a correction in LiDAR data using increment data of the species. Segmentation by Thiessen polygons reached an accuracy ranging between 75.2% and 91.7%. Estimating the 14 DBH the difference between the field was 3,1mm. For total height 0,19m was the difference between the data field and the LiDAR. Using the proposed methodology, it was possible to perform the measurement of the crowns of A. angustifolia and estimate dendrometric variables with satisfactory accuracy<br>Este trabalho tem como objetivo a medição automática de copas de Araucaria angustifolia utilizando dados LiDAR e indiretamente a obtenção de variáveis dendrométricas.

Quatro subáreas foram selecionadas para que fosse possível trabalhar apenas com árvores isoladas. O levantamento por varredura a LASER foi efetuado pela empresa Aeroimagem S/A de Curitiba, em janeiro de 2011 utilizando um sistema Leica ALS-60. No levantamento a campo, foram medidas árvores isoladas de A. angustifolia obtendo-se o DAP, altura total e 4 raios da copa na direção dos pontos cardeais. O levantamento à campo ocorreu em setembro e agosto de 2013. Para o delineamento das copas foi empregada a metodologia de segmentação de polígonos de Thiessen. Para o cálculo das variáveis dendrométricas, foi utilizado regressão linear para obter o DAP em função do diâmetro da copa. A altura pôde ser obtida diretamente dos dados LiDAR. Devido a sazonalidade entre o levantamento LiDAR e a coleta de dados a campo, foi necessário aplicar uma correção nos dados LiDAR utilizando dados de incremento da espécie. A segmentação por 12 polígonos de Thiessen atingiu uma acurácia que variou entre 75,2% e 91,7%. Na estimativa do DAP chegou-se a uma diferença de 3,1mm em relação ao campo.

Abstract:
This thesis engages various methods of calculation of the spatial distribution of precipitation and the evaluation of differences in totals of rainfall in a chosen catchment. The aim of this work was to choose suitable methods for the calculation of areal rainfall and subsequently to create those methods. Most methods were developed in the GIS program. The next objective was to explore differences in monthly precipitation from hydrological years 2006 and 2007 calculated in the catchment by chosen methods. Chosen methods for the calculation of the spatial distribution of precipitation in the catchment were: arithmetic mean, Thiessen polygons, isohyetal method and inverse distance weighting method. (IDW). As a suitable catchment was selected the catchment of the Kopaninský stream where relatively dense rainfall measurement network is installed. During the solution of this thesis the area of interest had to be extended by the area between the used rain gauges which was delimited in the GIS program. The reason for an enlargement was a fact that a decomposition of rain gauges in the catchment of the Kopaninský stream did not permit the creation of isohyetal lines in this whole catchment. During the calculation and the comparison of results of individual methods was found that results of used methods were surprisingly nearly the same. It was also stated that not even sufficient dense rain gauges network does not guarantee 100% exactness for calculating the amount of the precipitation in the selected area because of their extraordinary variability.

Abstract:
L'analyse régionale est une investigation délicate puisqu'une région est un ensemble hétéroclite et complexe d'invariants et de paramètres, visibles ou invisibles, mobiles ou inertes, en relation continue et interdépendante. Cerner toutes les composantes spatiales d'une région donnée est presque du domaine de l'impossible; seulement, il faut que les facteurs pris en considération soient essentiels et déterminants et permettent donc de mettre en relief les principaux écarts et décalages qui caractérisent une région quelconque.<br />C'est ainsi que l'objectif qui a déterminé la démarche de notre étude a été d'essayer de dépeindre la configuration spatiale antérieure et actuelle de l'Algérie à travers sa partie orientale qui est "l'Est Algérien". Pour tenter d'y parvenir, nous avons pris en considération trois types de maillages qui sont les territoires (wilayas et communes), le réseau urbain (toute taille confondue) et le réseau des voies de communication avec la trame routière et le réseau ferroviaire. Pour chaque type de réseau (territoires, réseau urbain et voies de communication), il a été à chaque fois nécessaire de présenter son évolution depuis presque l'antiquité, d'étudier sa configuration actuelle puis de la confronter avec des modèles théoriques en utilisant des outils d'analyse et d'investigation mis au point dans ce contexte.<br />Il ressort cependant que quel que soit le réseau ou le maillage pris en considération, l'Est Algérien s'est toujours montré comme un exemple typique d'un espace qui présente des formes opposées identifiables quelle que soit la méthode d'analyse utilisée. Il en résulte ainsi que la région, c'est à dire l'Est Algérien, est dominée par deux systèmes spatiaux dualistes :<br />+ un système classique traditionnel caractérisant les régions périphériques (partie occidentale du Tell, sud des Hautes Plaines ou la Steppe, les Nememcha, la région du Hodna et l'Atlas Saharien) qui accusent souvent des retards et des décalages négatifs dans tous les domaines;<br />+ un système spatial hérité légué principalement par le pouvoir colonial et qui se présente globalement comme une région polarisée linéairement le long des principales voies de communication en reliant les villes les plus importantes.<br />Il s'agit en fait du modèle de la région anisotropique qui se présente sous la forme d'une succession de sous-régions polarisées autour de grands centres urbains et bien connectés par les voies de communication suivant un axe préferentiel. De part et d'autre de ce premier système hérité subsistent des sous-systèmes spatiaux marginaux.

Abstract:
This paper addresses a new procedure for spatial and statistical analysis of water mains failure. We use this methodology to analyze and predict the spatial behavior of failure on the water mains network. The analysis is based on data from Sanandaj city in Iran over a 10 year period. It includes 395 mains failure which they were geocoded as discrete points. Prediction maps are constructed using different spatial interpolation methods, namely; the Thiessen polygons, the Density estimation, and the Triangulated Irregular Network model (TIN). Thiessen polygons are used for proximity and area allocation analysis of failure points. Density of failure points is calculated for each cell by summing the number of failures in the cell. TIN model generates a surface form interpolation of failure density. The study indicates that the construction of continuous surface from point dataset offers an interesting tool for the prediction of water main failures. It also provides comprehensive spatial information system that can be easily used by utility managers as a decision-support tool to set up and compare strategies for the renewal of water mains.
