Hello,
Thanks, that worked.
Looks like I missed the in-place band number selection flag ( -b ).
Does anyone know if I can direct output to another file, or do
I always need to copy the original file and 'burn' the values into an
existing duplicate file.
I guess it's just as easy either way.
Thanks again,
Peter

Perhaps something like
for i in {1..49}; do gdal_rasterize -burn -999 -b $i mask.shp
49bandenvi.dat; done

Hello,
On second thoughts, this is not really what I want.
I have a SHP format polygon vector file already.
I want to use that existing vector file to mask the ENVI format BSQ file
through all (49) channels.
(ie: 'mask' meaning set any values inside vector polygons to a specific
value within the output ENVI BSQ file )
Perhaps I'm missing something.

Peter,
I'm guessing you are using the gdal_polygonize.py script
for masking. Is that right? I am not aware of any particular
reason this shouldn't work for any update in place format
(ie. shows rw+ in the gdalinfo --formats list). ENVI is in
this list.
BTW, before we do a lot of work to investigate this you might
want to see if the problem persists with GDAL 1.9. GDAL 1.6.3
is getting pretty antique.
Best regards,
Frank

Hello,

I can mask a GTiff file using the SHP but ENVI file does not
appear to work. Gdal version is 1.6.3 .
The documentation appears unclear for any raster that is not
specifically GTiff.
Thanks,
Peter
