【摘要】：作为一个传统的地理信息科学和现代科学相结合的产物,地理信息系统应用已成为遥感信息技术,全球定位系统,互连技术于一体的综合学科的集合。地理信息系统(GIS)技术重要性体现在国土防御,城市管理规划,运输和交通,环境监测等方面,甚至涉及国家命脉相关的应用领域,在社会生产力发展的过程中,发挥了重大作用。因此,GIS已经成为一个竞争激烈的世界高科技的热点,同时,GIS技术的发展,在相关领域的应用也得到显着改善。 GIS在我国炮位侦校雷达领域的应用相对落后,此前的地图软件存在只能加载单一的栅格图源,无法兼容通用的矢量格式,无法完成图源的投影转换等诸多明显不足。本文针对炮位侦校雷达在地形分析、应急指挥等方面提出了更为广泛和复杂的作战应用需求,探讨了GIS与炮位侦校雷达地图软件系统的应用集成。主要研究了在GIS中如何加载显示多种数据图源及多图层管理方式,如何制作符号及实现图形标注的功能、多种投影变换的功能,并利用地形高程信息完成自动高程修正、遮蔽角计算功能,从而为使用者提供一定程度的辅助决策和多种图源支持和转换的功能,为工程推广的应用提供前提条件。
[Abstract]:As a result of the combination of traditional geographic information science and modern science, GIS application has become a collection of integrated disciplines of remote sensing information technology, global positioning system and interconnection technology. The importance of geographic information system (GIS) technology is reflected in the aspects of national defense, urban management planning, transportation and traffic, environmental monitoring, etc., and even involves the application fields related to the national lifeline, in the process of the development of social productivity, Played an important role. Therefore GIS has become a hot spot of high technology in the competitive world. At the same time the development of GIS technology and its application in related fields have been greatly improved. The application of GIS in the field of gun position detection radar in our country is relatively backward. The previous map software can only load a single grid map source, can not be compatible with the general vector format, and can not complete the projection conversion of the map source and so on. In this paper, the more extensive and complex operational application requirements of gun position detection radar in terrain analysis, emergency command and so on are put forward, and the application integration of GIS and radar map software system of gun position detection correction radar is discussed. This paper mainly studies how to load and display a variety of data sources and multi-layer management mode in GIS, how to make symbols and realize the function of graphic annotation, and how to realize the function of multi-projection transformation, and how to use terrain elevation information to complete automatic elevation correction. The function of shadowing angle calculation can provide users with certain degree of auxiliary decision support and conversion function of various drawing sources and provide the precondition for the application of engineering popularization.
