摘要
以Windows CE为操作系统,eVC为开发环境,结合eSuperMap相关工具,介绍了手持终端的嵌入式GIS开发;主要分析了嵌入式GIS的开发流程和相应的关键技术,具体涉及到WindowsCE软件开发环境的建立,电子地图的制作,GIS应用程序的开发3个方面;详细介绍了应用程序的整体架构以及eSuperMap类库在eVC中的具体运用,包括eSuperMap类库的结构分析、点按动作的实现、地图操作具体流程、GPS信息管理以及最短路径算法优化等。
Taking Windows CE as the operating system, the embedded GIS for portable terminal can be developed by utilizing eVC and the correlative tools of eSuperMap series. This paper mainly introduce an approach of designing an embedded GIS, and the corresponding important technologies. The paper also offers some measures of developing software on WinCE, manufacturing electronic maps and designing GIS applications. After analyzing the whole application structure, some details of the application are particularly introduced, such as structure of eSuperMap Libs, tap and hold gesture skills, map operation, GPS data management and optimizing the arithmetic of shortcut.
