Joint Campaign Command Of Military Geographic Data Model

Facing of outstanding characteristics about joint operations in modern high-technological warfare which armed forces take part in, the paper distinguishes military geographic feature for joint operations, analysis and makes sure its effective attribute and puts forward the difference between map data and military geographic data for joint operations. On the basis of discussion about principles that geography feature classification and coding should follows, it puts forward the basic principles of military geographic information classification, namely, orienting to object and orienting to geography entity, and , according to these principles classifies military geographic feature. It also brings forward the coding methods, namely, one base and four extension, and, base on the methods, finishes the geographic feature coding. At last, through coordinate conversion, the paper accomplishes the pick-up of geometric data of military geography feature from existed military digital map data and puts forward three algorithms to obtain attribute data from geometric data of military geographic information feature.
