Component-based Application And Development Of Gis In Defense Engineering

The modern warfare is rapidly transiting to high-tech, so the informationconfronting with each other will be higher and higher in the war in the future, this puts forward higher requirement to the speediness of commanding to fight. Under this kind of situation, building the digitized battle field and digitized army already becomes the main trend of military development in the 21st century. In order to make a response to the fast changing battle environment in time , commanders must make decision fast, so there are a set of military geographic information systems of digitization which is suitable for this field of the National Defense Project system, has already become the essential condition of commanding decision . With development of GIS(Geographic Information System), Concern database supports space datum store , various kinds of geographic application software appear, so the development of the application system of MGIS (military geographicinformation system) is ripe day by day.Starting with the conception of Geographical Information System (GIS), taking the JiNan Military Area National Defence Project as an example, using the theory and method of Military Operation Research, the main content of the National Defense Project GIS research was studied with pertinence; The system structure was discussed which involve functional design and structural design; This thesis has discussed the application of the geographic information system and development environment, and has made an introduction and compared on the developing platform of the geographic information system. According to the basic conception and characteristic of the space data and the Object Oriented holistic data model, this thesis has discussed the organization and management procedure of space data in MapX . Further this thesis has researched and adopted general methods about the controlling part of MapX to carry on processing and programming of geographic data in VB, This system adopts MapX platform, combines the data management procedure of Oracle Spatial electronic map ,In this paper, choosing Component-oriented GIS technology, I have developed some modules of the JiNan Military Area Nationai Defence Project GIS with GIS Component MapX4.5 and Adcvanced Language VB6.0,In this paper, the function,the ensemble structure and achievement of the system is expounded.
