The Research And Application Of Gis' Data Space Theory And Space Analysis Algorithmic

In many kinds of information management system,GIS is one of the most quickly developing systems.It is a architectonic aggregate of computer software and hardware. It can efficiently create, operate, analyse and display manifold data of geography or space reference, combine graphics and data,express the information of geography graphics. Proved in fact,GIS has good developing foreground in information management system.By developing of GIS,its design and exploitation utility is consummating day by day. Thereinto using mapX is a popular development model.This paper discusses basic theory of GIS,including its data model, data structure and data constitution.In instance of Mapinfo,narrates space topologic ralationship of GIS,and expatiates module technology and method of secondary-developed GIS. By study and research of these theories, on the basis of requiring of military information management, combining status of army barrack management work, penman empolder a management system adapted to army specialty. Furthermore,in military campaign or rehearse,it is very important how the compere make a right command and let army arrive the destination.therefore,By study and research about space analysis arithmetic of GIS, penman brings forward the problem of shortest route, and improves its arithmetic and realization method.This is a mat for later system development.
