| Abstract: | Abundant geological survey work was carried out in 20 century in China,of which data have been stored in "The Spatial Database of China Geological Survey Extent".The application system,named GeoWorkMap,has been implemented based on MapGIS 6.x.This paper introduces GeoWorkMap's requirement analysis and system design,especially the detailed design for some important modules is brought forward.Some characteristic functions are explored and their key techniques are expounded.It is estimated that the accuracy and efficiency of GeoWorkMap can meet the customs' requirements to access China geological survey extent spatial database,and great social benefits can be produced. |
