编译需要安装desktop或者Arcgis Engine.利用arcgis的ArcObjects(AO),实现加载地图

// AoTest1View.cpp : implementation of the CAoTest1View class

/*///////////////////////////////////////////////
首先打开上一节所建项目。选择菜单Tools->Options->Directories页在Include files里添加两个路径（如果你的ArcGIS的安装目录在其它盘，需做相应改动）：
C:\PROGRAM FILES\ARCGIS\COM
C:\PROGRAM FILES\ARCGIS\BIN

编译需要安装desktop或者Arcgis Engine.利用arcgis的ArcObjects(AO),实现加载地图，具有放大 缩小 平移 显示全图等漫游功能。
