| Abstract: | When constructing AM/FM/GIS systems,the core issue is to uniformly manage the geometry spatial-based and logic spatial-based objects.This paper presents the concept of spatial object model and the strict formalized definition is brought forth as well.By analyzing the data model of AM/FM/GIS and adopting object-oriented AM/FM/GIS data modelling method,the data storage and management in information infrastructure have been realized,which improves the running efficiency of AM/FM/GIS system. |
