Abstract

This paper has proposed a new method of efficient spatial data transmission in the client-side Web-Based GIS (Geographic Information System) which handles large-size spatial geographic information on the Internet. The basic idea is that, firstly, a large-size map is divided into several parts, where each part is called a "Tile", according to appropriate division granularity. Secondly, when an user requires a certain region in the map at client side, the GIS server only transmits spatial data in the tiles which overlap with the requested region. And the received data are stored in client local machine for reuse. Here a method of tile-division and tile-query processing has been provided. Comparing with traditional client-side Web-Based GIS, the performance improvement is achieved by the usage of the proposed method.
