to Jean,
I look up the help of ENVI, find the role of
"envi_convert_file_coordinates" is to "Use this procedure to convert
x,y pixel coordinates to their corresponding map coordinates". Maybe I
didn't have said clearly. My vector file and raster file had the same
coordinates, what I want to get is the pixels' data corresponding to
these points in vector file as soon as possible.so I don't know why to
use this procedure?
please forgive me for my poor knowledge,3q.
