Hi John,

If you can't use use gdal_translate to flatten an existing raster you can try creating one from scratch using one of the supported language bindings.

The python bindings work particularly well for this since you can hook into numpy.

See:

Cheers,

Dane

The output for gdal_rasterize has to be an existing geotiff. If I don't have an existing geotiff for the associated area how can I generate an empty geotiff based on the extent of the shape file that I will be using as the source for gdal_rasterize?

Thanks,
