| Computer science changing with each passing day has motivated the development of geographic information system greatly and brought infinitude of energy. With the rapid development of embedded and component-based technologies, geographic information system will be more widely used in civil and military domain.Associated with the Military Tactical Wireless Information Terminal project, the paper brings forward an new design of special GUI and Symbol Lib based on military criterion, which is to satisfy real-time capability and can be ported to different platforms by Object Oriented Design. Besides it is more important that users can customize information at will so as to meet the requirements in different professional fields.The paper firstly analyses the status quo, technology background, characteristics and application in embedded Geographic Information System. And then, it sets up the whole layered design logical frame structure by Object Oriented Designand some algorithm for speed. Finally, the paper draws a conclusion, which is tested and analyzed in the GUI and Symbol Lib based on military criterion. |
