As long I know, "tiled" images can partially loaded into the memory. This is their main advantage and the reason why them are so popular as map image formats. Nothing to do with compression. Using "tiled" images even a small PDA with poor memory amount can manage very huge maps (E.G. 2 GB compressed!!). Look at OziExplorer CE SW and ECW or OZXF file formats features.

Hello Giorgio,
the problem is not the image format itself. The difficulty is, that the image (uncompressed) must be loaded into the memory of the graphic card.

formats, like ECW. I don't know how difficult is the needed work for programmers.
