摘　　要：数据采集是GIS应用开发的基础问题之一。为了方便、高效地采集各类数据信息,以Linux为操作系统,QT为GUI设计软件,在嵌入式GIS平台MapGIS-EMS3.0开发包的支持下,设计了一套嵌入式GIS数据采集系统。先是依据需求分析,合理划分功能模块。然后编程实现了各类空间数据的存取、GPS数据的解析等具体功能操作以及地图浏览、数据编辑等人机交互界面。最后,成功将其移植到ARM目标板上。测试结果表明,该系统可以满足点、线、面等基本数据信息的采集以及定位服务的需求。Data acquisition is a basic problem of GIS application developing.To efficiently collect the various data information,an overall embedded GIS data acquisition system was designed.It is based on Linux operating system,using QT which is a GUI designing software,and supported by MapGIS-EMS3.0 which is an embedded GIS platform.Firstly,function modules were rationally divided by analyzing the needs.Then,the specific function programs were implemented,such as various spatial data accessing,GPS data parsing,and so on.Graphical interfaces for man-machine conversation such as map browsing and data editing were also achieved.Finally,the program was successfully transplanted into the target board-ARM processor.The testing result proves that the system can satisfy the location service demand and the basic information collection such as point,line and region.
