There's nothing especially terrain (or topography) about this afaics, and utility seems like the right approach rather than creating a format variant.
Actually Frédéric's intersting remark abou potential usage with "gdal raster tile" would actually make the driver approach a better choice.... unless we would extend "gdal raster tile" to accept a pipeline to go to create a final tile from a 'raw' one, like 'gdal raster tile --tile-pipeline="read ! encode-rgb --offset=-10000 ! write --of PNG" --extension png in.tif out_directory' .
But a ENCODE_RGB driver approach is more simple than implementing that. Even -- http://www.spatialys.com My software is free, but my time generally not. _______________________________________________ gdal-dev mailing list [email protected] https://lists.osgeo.org/mailman/listinfo/gdal-dev
