The Study Of Battlefield Situatuion Information System Based On GIS And RS

Battlefield situation information system, which is based on the geographical situation of environmental data and operational data for management and disposal objects, is an integrated system that receives, manages, stores, queries, adds up, analyses and shares the battlefield situation information and data. The introduction of Geographic Information Systems (GIS) technology makes the management of battlefield information enter the information and digitization era and becomes a powerful tool that leaders use to real-time control the situation in the battlefield thousands of miles away. The introduction and real-time update of Remote Sensing (RS) technology further make the information battlefield rich and accurate.At present, there is a wide variety of battlefield information systems, but they are based on vector map data to basically research and develop. The vector data characteristics determine its potential problems with data accuracy not high enough, slow rate of update and so on. With the development of satellite remote sensing technology, it is increasingly easy to access remote sensing image data somewhere, and even access accurate data about an airport, ports and other military fortress. How to use these data is the difficulty and focus of study. This involves:vector data and raster data matched; dynamic refresh and roaming large amounts of data of remote sensing image data; and how to resolve fusion and integration of the battlefield geographical information and combat situation information, especially how to solve the acquisition, storage, management and other issues in the battlefield situation information (including the goals and terrain).So, it is profoundly significant to do scientific research and develop the battlefield information system.Based on the platform of GIS secondary development ArcEngine and object-oriented programming environment VC ++6.0, using research and realization of battlefield information system as the clue, the paper mainly focuses on some problems below:1. It represents the basic technology and conception of battlefield information systems, introduces the development and research status of battlefield information systems, and emphasizes the great realistic significance of the study.2. It analyses and designs battlefield information systems. This system is separated into two layers. They are the foreground target data analog simulation and the back battlefield situation information acquisition, management, displaying and so on. This system structure adopts a form of network system. It uses multi-threading technology, UDP network group packets and encryption transmission technology. At the same time, it uses hash dynamic list to manage the target data and to draw tracks from different sensors.3. It designs and optimizes the topographic data and efficiency of the battlefield situation information system, and utilizes digital maps (vector structures) and more precise and rich remote image to jointly develop. It researches and applies Raster and vector matching technology, algorithm of layer, sub-blocks and cache management of raster images, dynamic display technology and so on.4. It uses the motion equation to simulate target track and designs aircraft, ships and other target model. In the direction of component software development thought, it uses ActiveX controls and COM formation technology to realize the battlefield information system.
