Hi I can see that the COG driver does some pre-processing (eg. overviews and reprojection) and then passes on the work to the GTiff driver. However I've been trying to understand the relationship between the create options which the COG driver accepts and the create options for the GTiff driver.
Some of the options are explicitly copied over, such as: BIGTIFF NUM_THREADS GEOTIFF_VERSION SPARSE_OK some have a slightly different name (why?), such as: BLOCKSIZE (instead of BLOCKXSIZE) LEVEL (instead of ZLEVE) some are necessarily additional, such as: OVERVIEWS TARGET_SRS some are removed, such as: TILED (because it's implicit in COG) but that leaves a whole bunch of others which are not documented, and I can't see in the code how they might be handled: NBITS DISCARD_LSB ALPHA PIXELTYPE PROFILE PHOTOMETRIC GEOTIFF_KEYS_FLAVOR TFW, RPB, RPCTXT Andrew
