摘要：

This paper studies the methods and strategies of the network update of the land survey spatial data based on embedded terminal equipment and server and application of multi-level distributed heterogeneous land spatial database. Web services network model has been used to do the design and implementation work of embedded system of land survey data update. The main procedure of spatial data real-time network update method in this article includes: web services network asynchronous transmission, wireless transmission based on GPRS, spatial data real-time updating, layer-grid index by applying the model of setting many levels and blocks, interactive operations between spatial data and attribute, location services and automatic acquisition based on GPS.
