Abstract:With the continuous evolution of modern battlefield models, military geological factors, as one of the five major elements of the battlefield environment, have increasingly garnered attention for their importance. Military geological data is a specific carrier of these factors. More and more collection methods have led to surge in geological data related to the battlefield environment. In order to solve the bottlenecks such as data integration of multi -source, formats, scale, and database types, this article is based on MapGIS10 as the base platform to study military geological data conversion, data source unification, data consistency maintenance, and data sharing among different application systems in heterogeneous environments.This research holds significant practical value for providing service support related to military geological factors.
