Abstract: To avoid the complexity of special GIS software, this paper, taking the GIS layer processing module in a campus ground object resources’ administration system based on MapObjects for instance, discusses the method of how to realize the function of GIS layer’s processing. The effective programme can help users to complete the processing of vectorgraph layers easily, improve the efficiency greatly. The experiment results showed that the MapObjects’s functions are very suitable for processing geographic information, and is of strong advantage.

Key words: MapObjects, geographic information system, vectorgraph layer, coordinate system
