在arcgis里圈画log的区域，要注意shapefile文件和所有底图是同一个extent，同一个地理参考系，同一个地理水准面，同一个地理投影坐标系在图层的properties查，也就是roi可能会出现其中一个图层上，但不能出现在另一个图层上。反正数据的坐标信息和范围一定要一致。在envi里圈画roi的区域，基于A1的结果，直接在两个窗口打开roi文件，goto到相应的区域arcgis图像log对比图就可以了。

我也遇到了类似的问题。通过代码测试了好多次。

（1）在保证授权许可没有问题；

（2）文件路径和文件名没有问题；

在以上两种情况下，可能是shp数据文件出现了错误。可以用ArcMap打开这个文件试试看，是不是这个错误。

1、建个记事本文件，示例如下：x,y,z102,33,100103,345,1022、在ArcGIS中添加最好的上述记事本文件，通过Tools菜单下的AddXYData命令（指定X,Y和坐标系统，如果你的点是地理坐标且通过GPS接收仪获取的，坐标系统选择GCS下的WGS84）。3、如果点可正常显示在合适位置，将该数据导出成shapefile就可以了。
