摘要
在ARM-Linux系统中,对MapInfo地图数据(mif、mid)进行分析,建立合适的GIS数据结构。提出GIS改进算法,利用C++程序语言,设计嵌入式GIS模块,然后通过QT/E图形库,使GIS空间数据与属性数据结合显示。最后将嵌入式GIS应用于电子导游系统中,并取得良好效果。
In this paper the author analyses the MapInfo map data ( mif and mid) in ARM-Linux system and establishes appropriate GIS data structures. An improved GIS algorithm is proposed as well. The author uses C + + programming language to design the embedded GIS module,and makes the GIS space data and the attribute data display together by QT/E Graphic Library. Lastly the embedded GIS is applied to the Electronic Guide System and that achieves good results.
