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

[Pinner, Luke]

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,

Is it possible to use ESRI SHP polygon file to mask
ENVI  BSQ img format files with more than 1 band?

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
