I am using GDAL 2.4.0-5. I was able to do this in previous versions of the OSGeo4W distribution. This is what happens when I try to create a new LERC-compressed MRF file:\\ gdal_translate -co ""COMPRESS=LERC"" -of MRF input.tif output.mrf\\ Warning 6: 'LERC' is an unexpected value for COMPRESS creation option of type string-select.\\ ERROR 4: GDAL MRF: Error setting compression\\ ERROR 10: Can't create output.mrf\\ And this is what happens when I try to read an existing LERC-compressed MRF:\\ gdalinfo test.mrf\\ ERROR 1: GDAL MRF: Compression LERC is unknown\\ gdalinfo failed - unable to open 'test.mrf'" defect closed minor Package fixed
