TFW File Format

ArcView World file for TIF image (GIS application)

The TFW file extension is used for plain text files that store X and Y pixel size, rotational information, and world coordinates for a map that is stored as a TIFF image in a GIS application. A GIS (geographic information system) enables you to envision the geographic aspects of a body of data. Basically, it lets you query or analyze a database and receive the results in the form of some kind of map.

TFW files must be saved in the same directory as their accompanying TIFF  map images. Such maps are typically used with ESRI’s Arc series of mapping applications, as well as Google Earth and Global Mapper Software.
