Abstract: | In view of the shortcomings of the existing agricultural economy information system, a transformation programme of using Geographic Information System technology was proposed. The GIS for agricultural economy information service was designed and developed based on ComGIS software Supermap Objects and development language C#.Net,and the agricultural economy information database was established.The new system has realized the spatial inquiry and the spatial analysis of agricultural economy message data, provides the auxiliary policy-making method and the auxiliary analysis basis for all levels of Agriculture department, raised the agricultural economy information service level.This paper elaborates on architecture of the system,module of function,and the basic process development of GIS using SuperMap Objects components in the environment of C#.Net. |
