✅ ArcGIS TIFF World File

ArcGIS TIFF World File .tfw file icon
TFW file is an ArcGIS TIFF World File. TFW files are the ASCII files containing information for geocoding image data so TIFF images can be used directly by GIS and CAD applications. Some image formats, such as ERDAS IMAGINE, BSQ, BIL, BIP, GeoTIFF, and grids, store the georeferencing information in the header of the image file. ArcGIS uses this information if it is present. However, other image formats store this information in a separate ASCII world file, since it contains the real-world transformation information used by the image.
