Web-Based GIS
Abstract
One of the main concerns on Web-based geographical information systems (Web GIS) is related to performance issues, as these datasets need to migrate, as fast as possible, from server to client tiers (Peng & Tsou, 2003). This is the problem of generation and transmission of the digital maps, which are suitable for user needs. Another important issue is to enable fast and easy Internet GIS application deployment. In this chapter, we discuss solutions proposed for Web GIS based on the vector format, particularly the iGIS framework (Baptista, Leite Jr., Silva, & Paiva, 2004). The iGIS is a Web GIS that renders maps using multiresolution techniques, and enables user interaction them, using the W3C SVG specification. The chapter also addresses the issues that affect Web GIS performance, presenting an overview of the techniques that increase Web GIS performance and the results obtained by using the iGIS framework.
