I set off some tasks running gdal2tiles.py for certain rasters with a zoom range of 8-20. To my dismay I return the next day to find only images for zoom level 20 have been created. I understand that this is a big range, but I don't think this should be a problem.
The command to generate images:
gdal2tiles.py warped_file.tif output_dir --s_srs 'EPSG:4326' --zoom=8-20 --processes=3 --exclude
The warped file is produced by this command:
gdalwarp -s_srs 'EPSG:27700' -t_srs 'EPSG:4326' file.tif warped_file.tif
Is there a reason why only zoom level 20 was created?
