World Wide Web Geographical Information System(WebGIS) is the combination of Internet and modern Geographical Information System. Since its naissance

it has brought great influence to the national economy and people's lives. After the study of WebGIS and its solutions

this article proposes and implements a new MAPGIS -Web solution. This solution is not only based on ASP components technology

but also based on MAPGIS--a Chinese GIS software. It adopts the fashionable three layers Client/Server architecture as its system structure. In this architecture

the GIS Data Server layer take charge of restoring the GIS data

and the WebGIS Server layer take charge of running the GIS data

and then the Browser layer take charge of submitting the command for the GIS data and getting the common HTML as the result. So this solution has a good platform independent quality at the Client

and it's can be reused easily

and it can help people to set up WebGIS Server quickly and easily.
