A Research for 3D WebGIS based on WebGL

This paper introduced a way to implement 3D WebGIS system which was based on WebGL technology. The system used Ellipsoidal Mercator projection and WGS84 coordinates, made JSON file format for network transformation, described popular method for tile map service, and finished a prototype system of 3D WebGIS. The prototype system was applied in a Remote Sensing Catalogue Service system. At last the paper discussed what's the good and bad aspects of WebGL.
