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

[Peter Willis]

Hello,

 

I was using gdal_rasterize  directly rather than  gdal_polygonize.py .

.No  gdal_poygonize.py found for my revision..

 

I was forgetful of -formats via gdalinfo.  This shows rw+ for ENVI format
which is what I need.

Upon looking I find that I have already installed revision 1.9 in another
/usr/local directory.

Perhaps I should use the more recent revision for attempting this.

 

Thanks for the pointers,

 

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

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
