I read and I read opinions and topics regarding this tool but I am still unclear if I should us this or not.
In my project I have thousands off tiff files which need to be put on a map. The problem is that while creating the tiles (map tiles) it runs really slow, especially when it needs to put a lot of tiffs on a tile..
I heard that gdaladdo can speed this up but I am unsure if this could affect the quality of the tiff files and/or any other side effects.
Unfortunately, I do not have a backup for the files and while I was testing this on a few bunch of files, the only thing I saw was the increase in size for each of the files.
If anyone had positive (and especially negative) experiences using this tool, I would appreciate an example, advice or anything you think can help.
