If I do:
gdal_translate -co "TILED=YES" -co "BLOCKYSIZE=512" -co
"BLOCKXSIZE=512" -co "COMPRESS=JPEG" Sur2_A1.tif Sur2_A1.procesado.tif
I get thousands of:
ERROR 1: JPEGSetupEncode:PhotometricInterpretation 3 not allowed for JPEG
and a 50KB .tif from a 869MB .tif.
My images aren't in the right format?
