  • TIFF and TIF Files Explained How to Open Them

    Dec 21, 2020 · TIFF is an acronym for tagged image file format. GeoTIFF image files also use the TIF file extension. These are image files that store GPS coordinates as metadata with the file, using the extensible features of the TIFF format.

  • How to georeference images in ArcGIS | Map and Data Library

    Georeferencing is the name given to the process of transforming a scanned map or aerial photograph so it appears “in place” in GIS. By associating features on the scanned image with real world x and y coordinates, the software can progressively warp the image so it fits to other spatial datasets. This tutorial will explain how to georeference a raster image in ArcGIS so it can then be used as an overlay or for digitizing purposes.
