Web-Based Geographic Information System for UWRSR Evaluations

Visualizing Transit Through a Web Based Geographic Information System

Currently in many major cities, public transit schedules are disseminated through lists of routes, grids of stop times and static maps. This paper describes a web based geographic information system which disseminates the same schedule information through intuitive GIS techniques. Using data from Calgary, Canada, an map based interface has been created to allow users to see routes, stops and mo...

Web-Based Instruction in Geographic Information Systems

A knowledge-based automated vectorizing system for geographic information system

Recently, there is a growing interest from various fields of studies in GIS which promotes efficient storage and retrieval of geographic information. The development of automated vectorizing system, an input method for GIS, is of extreme importance due to the fact that this part of constructing a GIS has been time consuming. Most vectorizing systems require users to set parameters as appropriat...
