[gdal-dev] Use GDAL to combine (rather than mosaic) rasters

2013-04-28 Thread Ritvik Sahajpal
Is there a GDAL command which can combine multiple rasters so that so a
unique output value is assigned to each unique combination of input values,
like the combine command in ArcGIS?

gdal_merge seems to mosaic rasters so it is not exactly what I need.

thanks!

Ritvik,

You can use gdal_calc.py to perform computations with multiple rasters. It
is not among the officially released scripts.
http://trac.osgeo.org/gdal/browser/branches/1.10/gdal/swig/python/scripts/gdal_calc.py
You can download the script from that page. The usage is described in the
comments.
