Laura, This might be one method for your multiple NoDATA issue. There is in the python example in the *samples *directory called val_repl.py (value replace). It allows you to change one value to another but by switching the line below you can make it greater or less than a certain value. This might allow to first map all you NoDATA values to a single NoDATA before running gdalwarp.
original val_repl.py: http://svn.osgeo.org/gdal/trunk/gdal/swig/python/samples "val_repl_greater.py" is simply the sample "val_repl.py" (from link above) with one line changed replace scanline = numpy.choose(numpy.equal(scanline,inNoData),(scanline,outNoData)) with scanline = numpy.choose(numpy.greater(scanline,inNoData),(scanline,outNoData)) good luck, Trent On Mon, Oct 28, 2013 at 6:57 AM, laura0 <[email protected]> wrote: > Hi all, > I have discovered gdalwarp options -srcnodata -dstnodata support just 1 no > data value per band.
