摘　　要：研究了基于嵌入式ARM-Linux平台的MiniGUI,在此环境下实现了MapInfoTAB格式的地图的显示和操作。首先,通过建立交叉编译环境和平台运行环境,完成MiniGUI到ARM-Linux平台的移植;然后,阐述了如何利用GDAL/OGR库读取MapInfo中的TAB、ID、DAT、MAP等格式文件的地理坐标数据和坐标系的信息,并通过坐标系转换对应到MiniGUI的显示区;最后在ARM-Linux平台的LCD上显示,系统性能达到预期目标。In this paper the MiniGUI based on ARM-Linux platform is researched,in which a map of MapInfo's format(TAB,MIF,-)can be displayed and operated by using the GDAL/OGR library.Firstly,across-compiler and running environment is built,then the MiniGUI system is transplanted into Embedded ARM-Linux platform;secondly,the MapInfo's coordinate data and coordinate information is accessed by using GDAL/OGR library,if necessary,the ellipse coordinate is transformed to the ichnographic coordinate,and finally,the map is displayed on the platform's LCD.The experimental result indicates that the system performance achieves the anticipated target.
