Multi-source Spatial Data Code on the Global Partition Method

The multi-source spatial information code is the key of spatial data organization, and the base of spatial information searching, retrieval and the data mining.In this paper, the author establish a spatial information cataloging system combined with the current characteristics and application of multi-source according to the shortage of traditional coding technology. The author also proposed a set of global partition encoding spatial information on the basis of GSM to establish a global unique identification code spatial information GeoID then realized global information sharing.
