【摘要】 随着嵌入式操作系统的迅速发展和地理信息系统应用领域的日益广泛，嵌入式地理信息系统的研究成为目前地理信息研究的重要领域。论文从地理信息系统在嵌入式操作系统平台上的开发入手，介绍了嵌入式地理信息系统开发过程中应用的技术和算法，并利用军事地理数据设计了一个实用的地理信息系统。 论文重点阐述了如何利用地理数据，运用计算机图形学、地理信息及可视化编程等相关技术实现在Windows CE.net 4.1平台上运行的地理信息系统。系统利用分层显示技术实现地图的分层显示，利用图形平移技术实现地图漫游，利用图形转换技术完成地图缩放，同时运用地形分析有关算法在数字高程模型(Digital Elevation Model，DEM)的格网模型上实现地形分析(即距离计算、面积技术、可视性分析等基本内容)。 在本文有关技术和算法基础上，通过eMbedded Visual C++4.0编程，实现了一个界面友好、处理速度较快、功能模块相对独立的地理信息系统。经过理论分析与实际使用验证，它是一个能满足实际应用需要的嵌入式地理信息平台。更多还原

【Abstract】 With the development of embedded operating system and the rapid growth of application domain of GIS, the research on embedded GIS becoming more and more important. This thesis began with the GIS development running on Windows CE , then introduced the algorithms and technique used in the embedded-GIS development process, and designed a applied GIS by using military geographic data.It has been discussed in detail how to use geographic data and these technologies ,such as computer graphics, GIS and visual programming ,to develop a GIS running on Windows CE.net 4.1 .In this thesis, we used hierarchical display technique to hierarchically display map, graph translation technique to translate map, and graphics transformation technique to zoom map. At the same time, we used algorithms related to terrain analysis to realize the terrain analysis (including distance and area calculation, viewshed analysis) based on the grid model of the Digital Elevation Model .On the basis of these algorithms and technique mentioned in this thesis, a GIS has been realized by eMbedded Visual C++4.0 programming. This system is characterized by fast computation , friendly interface and independent functional module. As an embedded GIS platform, it has been theoretically and experimentally verified to have met the needs of practical applications.更多还原
