Firstly

the development and application of digital city are introduced. Aiming at the complexity of constructing digital city

the key issues and implementation scenario of constructing digital campus based on GIS component are explored

which will give a practical method and useful reference for digital city. Adopting the GIS platform Geo-Union

a digital campus of Peking university (PKU campus) is built. The architecture of PKU campus is based on Browser/Server mode

which consists of four layers: Browser

Web Server

Geo-Union Server and Spatial database server. The spatial information of PKU campus is organized as spatial entity

map layer and map and stored in Oracle8i.According the distribution of the campus

the spatial information consists of five parts: environment

main campus

Yan-bei campus

Chang-ping campus and medicine campus. The functions of PKU campus include information services both inside PKU and around PKU

such as map exploring

Web linking

site locating

spatial querying and navigating. The implementation method of PKU campus is based on WebGIS component and ASP. Two secondary developing components (GisView and PicView) are designed to integrate visualization

map operation

human-user interaction for map and image.PKU campus integrates all-sided service information in PKU

which will provide a convenient information channel for all members of PKU and other users

and will be a new window for exhibiting the image of PKU.
