FAQ
GTI to IFF Conversion
What are GTI files?
GTI (Raster Tile Index) is a small file that turns a large collection of map or image tiles into one seamless virtual picture. Instead of storing any pixels, it points to the individual raster files, which may be aerial photographs, satellite scenes, or terrain tiles, and describes where each of them lies on the map. A program that opens the GTI file sees one continuous image and loads only the tiles needed for the visible area, which makes it practical to work with archives of thousands of files without merging them first. The format appeared in 2024 and is stored as a short XML file with the .gti extension, or as a tile index in a GeoPackage or FlatGeobuf file.
What are IFF files?
IFF is an old image format associated with Amiga computers — a brand connected to Commodore, which used to be popular in the 1980s and 1990s. Commodore was one of the first types of personal computers to gain wide popularity among home users. An IFF file most likely contains an image that was created or edited using an image handling program on an Amiga computer. IFF files are currently considered obsolete and uncommon, so opening them with regular image viewers might be difficult.
