THE STATISTICAL AND GEOGRAPHICAL ANALYSIS ON THE IMPACTS OF SOCIOECONOMIC CHARACTERISTICS ON BUS-STOP DAILY BOARDING IN RICHMOND CITYZhao, Yue 01 January 2015 (has links)
At present, Richmond, Virginia only has bus transit services provided by the Greater Richmond Transit Company (GRTC) and primarily concentrated within the boundary of Richmond City. GRTC is impacted by both supply-side and demand-side factors, notably socioeconomic characteristics of bus riders, bus ridership is unevenly distributed across different bus stops.
This thesis will conduct statistical and geographical analysis on the impacts of socioeconomic characteristics on bus-stop daily boarding in Richmond City. The statistical analysis includes both correlation analysis and regression analysis, assuming one dependent variable (bus-stop daily boarding) and fourteen independent variables (most of which describe socioeconomic characteristics of bus riders) at aggregated census block group levels. The research concentrates on local bus routes and the block groups with local bus stops in Richmond. This empirical study aims to identify the significant factors impacting bus ridership and assess the bus service situation for affected block groups (under-served or over-served). The study outcomes, such as the number of bus lines as the most important factor impacting ridership, will have important implications for Richmond’s local transit planning and decision-making.

Interopérabilité des modèles géométriques pour les Systèmes d'Information Géographique : applications de la norme ISO 19107François, Axel 07 October 2011 (has links)
Le contexte économique actuel montre que la représentation et l'analyse des données dans l'espace 3D croît de plus en plus dans les Systèmes d'Information Géographique (SIG). Le nombre d'applications SIG est en constante augmentation dans de nombreux secteurs d'activités comme par exemple la Défense, l'Aménagement du Territoire ou la Sécurité Civile. Cependant, nous voyons l'émergence d'une forte demande pour l'analyse 3D dans les SIG. Ces développements nécessitent une standardisation des structures de données et d'échanges. Cette démarche est réalisée par l'Open Geospatial Consortium (OGC) et l'organisation internationale de normalisation (ISO). Une norme récente (ISO 19107:2003) décrit les objets complexes à prendre en compte et les traitements qu’il est possible de leur appliquer. Elle cherche à mettre en place l’interopérabilité des échanges et des analyses de données géométriques et topologiques dans les SIG. Actuellement aucune implémentation informatique complète de cette norme n’a été encore réalisée, compte tenu de son niveau d'abstraction. Une version simplifiée a toutefois été développée pour des objets uniquement 2D (ISO 19137:2007). Ce travail de thèse propose la modélisation et l’analyse d'objets complexes dans un espace tridimensionnel, et les traitements associés pour réaliser une première bibliothèque de fonctionnalités conforme à la norme ISO 19107. De plus, cette norme est actuellement portée en révision au sein du consortium OGC (Open Geospatial Consortium, www.opengeospatial.org) avec une nécessité de correction et d’évolution. Les travaux menés jusqu'à présent ont permis d’apporter une contribution pertinente avec l'ajout de nouvelles primitives géométriques, l'harmonisation de primitives par l'usage de courbes et surfaces paramétriques rationnelles. Les travaux sur cette norme ont permis également l’élaboration d'une application au sein de la société GEOMATYS, rendant possible la modélisation et l'analyse 3D d'un trafic aérien reposant sur des données SIG. / In the current economic context, the representation and the analysis of 3D data is growing more and more in the field of Geographic Information Systems (GIS). The number of GIS applications is constantly increasing in many industries, such as Defense, Regional Development and Civil Security. However, we can point out the emergence of an important request for 3D analysis in GIS. These developments require a standardization of data and exchange structures. This is carried out by Open Geospatial Consortium (OGC) and International Organization for Standardization (ISO). A recent standard (ISO 19107:2003) describes the complex objects to be taken into consideration and the associated treatments that can be used. It aims to develop interoperable exchange and analysis of geometric and topological data in GIS. Currently, no complete implementation on a computer of this standard has been done yet, regarding the level of abstraction sought. However, a simplified version was exclusively developed for 2D objects (ISO 19137:2007). This thesis proposes the modeling and the analysis of complex objects in three dimensional space, with their associated treatments. The objective is to create a first library whose the features are conform to ISO19107. Moreover, this standard is currently under review within the OGC Consortium (Open Geospatial Consortium) with a need for correction and evolution. The work done until now have enabled us to make a meaningful contribution with the addition of new geometrical primitives, the harmonization of primitives through the use of rational parametric curves and surfaces. The works on this standard also allowed the development of an application within the GEOMATYS company, making possible the 3D modeling and analysis for traffic simulation based on GIS data.

Ekologické zemědělství v ČR (geografické analýzy) / Organic farming in the Czech Republic (geographic analysis)SEDLÁKOVÁ, Lucie January 2015 (has links)
The aim of this thesis is processing ÚZEI data for organic agricultural production in individual regions of the Czech Republic in the form of maps and graphs that provide a basic overview of the territorial deployment of crop and livestock production of organic farming. For crop production are given the following information: sown area in the conversion period and in the full organic mode, organic production and the average yield. Data of livestock in organic farming provide information about the numerical status of the individual categories of livestock. Part of the thesis is also devoted to the realization of crop and livestock organic products on the market in 2012. The thesis is part of the project Gaju 019/2013 / S.

Teoretické a metodologické problémy produkce evidence v adiktologii. / Theoretical and Methodological Issues in the Evidence Production in the Addictology.Petruželka, Benjamin January 2021 (has links)
Background: Indicators, primarily administrative indicators, the field of addiction studies are considered imperfect, approximate and associated with a number of issues. Among others, these issues are based in the fact that administrative indicators are not primarily research indicators. In spite of their shortcomings, these indicators are an important part of public policy making, as they are part of strategic documents and can be used to assess the situation and develop policies in the field of addictive substances. Objectives: The first objective of this thesis was to identify issues related to the administrative indicators. The second objective was to propose the directions for development in areas that had been identified as problematic, i.e., the theoretical and methodological framework. The third objective was to apply selected procedures that had been proposed in the previous parts of the thesis. Methods: To meet the first objective, the basic issues associated with the use of administrative indicators were identified using a narrative review of the literature. The directions for the development of the theoretical and methodological framework were elaborated, responding to the issues identified in the review. The third objective was achieved by application of the approaches described in the...
