Abstract
  • We have developed a framework for Web-based GIS/database (WebGD) applications that allow users to insert, query, and delete data with map interfaces displayed by Web browsers. The framework uses such open source software packages as Minnesota MapServer, PostGIS, and PostgreSQL. With this framework, we can create the map interface of a new WebGD application only by providing configuration files. Those configuration files define the contents, appearances, and interactions of the legend, the quickview mechanism, and the map function tools. The map area needed for an application can be covered by multiple regions, each with its own set of map layers and region specific parameters such as a map projection and a map extent. Spatial references for different map regions can be dynamically switched.
