They use completely different techniques. gdal_translate will be faster than gdalwarp when no reprojection, cutlining, etc. is needed gdalwarp can only work with output drivers that have full random-write capabilities (e.g. TIFF), whereas gdal_translate can support, in addition to those ones, all drivers that have create copy mode (e.g PNG) See https://trac.osgeo.org/gdal/wiki/FAQRaster#Whywontgdalwarporgdal_mergewritetomostformats Even -- Spatialys - Geospatial professional services http://www.spatialys.com _______________________________________________ gdal-dev mailing list [email protected] https://lists.osgeo.org/mailman/listinfo/gdal-dev
