Is it possible to use ESRI SHP polygon file to mask<br>
ENVI BSQ img format files with more than 1 band?<br>
<br>
I can mask a GTiff file using the SHP but ENVI file does not<br>
appear to work. Gdal version is 1.6.3 .<br>
<br>
The documentation appears unclear for any raster that is not<br>
specifically GTiff.<br>
<br>
Thanks,<br>
