Abstract
Geographic Information System based on Web is also called WebGIS which is the newest development technology of GIS. Its architecture is based on the existing technology of Internet/Intranet. WebGIS provides more widely geographic and spatial information service by widely using the Web resources, so it is the primary trend of GIS's development on the current international. This paper analyzes the concepts and characteristics of WebGIS, anatomizes the architecture of WebGIS, discusses the key technology of WebGIS's development, and points out the development trend of GIS technology, and give an implemented instance of GIS based on Web in which Web Services technology is used.
