The study of spatial relationships has been one of the most active areas in GIS research over the past twenty years. Many formal models have been proposed for the definition of topological or cardinal relationships. However, these approaches often consider space as a static continuum which does not integrate the temporal dimension. Recent progress in spatio-temporal GIS research attempts to ext...

The aim of this study was to establish a preferred methodology for updating of the spatial database and monitoring the changes of a settlement in Tanzania. In summary, change detection problems can be viewed as the consequence of an increased desire for up-to-date information about the development and changes in a GIS environment to guide urban planners, urban decision-makers, and managers. Two...

This paper seeks to understand the use and the consequences of Participatory Geographic Information System (PGIS) in a Mexican local community. A multilevel framework was applied, mainly influenced by two theoretical lenses – structurationist view and social shaping of technology – structured in three dimensions – context, process and content – according to contextualist logic. The results of o...

This document is intended to help people without formal training in map design learn to produce maps for publication or electronic display using ArcView, a desktop geographic information system (GIS). A GIS is a system for the display, analysis, storage and retrieval of information about places on the earth. GIS is a useful tool for exploring information and communicating your discoveries to ot...

We review urban models useful in transportation planning, focusing especially on ones that are based on geographic information systems (GIS) software. We then describe UPlan, a simple model written by us in the ArcView GIS. Several different applications of UPlan are outlined, involving transportation planning and the analysis of the growthinducing effects of new facilitites, to demonstrate its...

The main goal of this paper is to present the conceptual framework for engaging youth in urban planning activities that simultaneously create locally meaningful positive change. The framework for engaging youth interlinks the use of IT tools such as geographic information systems (GIS), agent-based modelling (ABM), online serious games, and mobile participatory geographic information systems wi...

An Intelligent System for Map Data Processing in Geographic Information Systems W. Feng University of Illinois at Urbana-Champaign 1304 W. Spring eld Avenue Urbana, IL 61801 E-mail: [email protected] Abstract A geographic information system (GIS) allows users to collect, analyze, and manage a large amount of spatially referenced data. Our GIS incorporates computer graphics, image processing, dat...

One of the most important goals of public participatory geographic information systems (PP GIS) is to improve citizen’s participation in planning processes. Does this really happen? Unfortunately, very little empirical research exists which would testify or falsify this hypothesis. In the process of trying to involve the citizens in the planning processes, we observe the effect of rational igno...

The Nasca lines or geoglyphs in southern Peru are known as one of archaeology's greatest mysteries. Since the 1980s, however, new approaches have helped to better understand their function and meaning. The recent photogrammetric recording of 1 500 geoglyphs in the vicinity ofPalpa enabled for the first time a GIS-based analysis. Geoglyph visibility is one of their most discussed traits. While m...

Following a comprehensive literature review, this paper looks at analysis of geohazard using remote sensing information. This paper compares the basic types and methods of change detection, explores the basic principle of common methods and makes an respective analysis of the characteristics and shortcomings of the commonly used methods in the application of geohazard. Using the earthquake in J...
