Abstract:

The GIS system in Vietnam is mainly operated in computer-based application and the data sharing is only via LAN which is not efficient and the usefulness of the system is reduced as the time passing. In some part in Vietnam, there are a number of large scale GIS which enable the sharing, data query and spatial analysis over the Internet. However, these systems can only support data query and analaysis using personal computer software. The other may support using of geo-spatial data via web browsers but with limited application. This paper is for sharing the information on Internet GIS, comparing the computer-based and web-based application and propose a web-based application for land information systems.
