Hey Folks,
I’m trying to give an easier way for my users to create COGs (Cloud Optimized GeoTIFFs) through QGIS? I know they can use gdal_translate from the command line from the OSGeo4W. But I’d like to give my newer users more options that are less intimidating.
Hi Gregory,
If you want to keep it a gui, you may need to dive into some QGIS - specific GUI programming.
Another option is to put a python wrapper around the gdal_translate command. Write a make_cog.py that prompts for the input directory of files, and the output filename. The python script will run gdalbuildvrt to create a virtual raster layer of the files in the directory , and then gdal_translate to convert the .vrt file to a COG. If you have it documented that the shared drive X: , has a raster_utils directory, then open the OSGeo4W shell and run python3 X:\raster_utils\makecog.py
