Action Plan: Tagged Image File Format - GeoTIFF

Last Updated 2/5/2014

Description: Tagged Image File Format, or Tiff files, are some of the most common Raster Image Formats in use. Created by the Aldus Corperation which was later aquired by Adobe, Tiff'stechnical specifications have been released by Adobe. It was last updated in 1992, its current version is 6.0.

Codec: The GeoTIFF format is used to store geospacial data based on Tiff 6.0.

Software:  Global Mapper, USGS's dlgv32, ESRI ARC/INFO, ESRI ArcExplorer, ESRI ArcView , ERDAS IMAGINE , PCI’s EASI/PACE ,MAP INFO , and Python Imaging Library all support GeoTIFF.

Long Term Preservation Plan:  GeoTiff is a widely adopted and supported open and documented format owned by Adobe. Its ubiquity in the world of geospacial data formats makes it a very low risk format. No need for migration at present. It is however limited to 4GB of data per file. This has prompted the development of the BigTIFF format.
