no problem. gdal and osr will be used in the input layer, where we 
expect to handle DEMs with standard projections.
we've alredy implemented the transformation directly with proj4,
and the output of the 'geocent' data is done by hand (without gdal).

so i don't need any additional feature at the moment.

thanks,
