[gdal-dev] Using gdal_rasterize to mask ENVI file Using ESRI SHP format Vector

[Peter Willis]

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

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

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
