GeoTIFF is a public domainmetadata standard which allows georeferencing information to be embedded within a TIFF file. The potential additional information includes projections, coordinate systems, ellipsoids, datums, and everything else necessary to establish the exact spatial reference for the file. The GeoTIFF format is fully compliant with TIFF 6.0, so software incapable of reading and interpreting the specialized metadata will still be able to open a GeoTIFF file. The public domain comprises the body of all creative works and other knowledge—writing, artwork, music, science, inventions, and others—in which no person or organization has any proprietary interest. ... Metadata is data about data. ... This article is about TIFF, the computer image format. ... The word projection can mean more than one thing. ... See Cartesian coordinate system or Coordinates (elementary mathematics) for a more elementary introduction to this topic. ... Definition In mathematics, an ellipsoid is a type of quadric that is a higher dimensional analogue of an ellipse. ... It has been suggested that this article or section be merged with Geodetic system. ...
History
The GeoTiff format was originally created by Dr. Niles Ritter while he was working at the NASAJet Propulsion Laboratory. NASA Logo Listen to this article · (info) This audio file was created from the revision dated 2005-09-01, and does not reflect subsequent edits to the article. ... The Caltech Jet Propulsion Laboratory (JPL) near Pasadena, California builds and operates unmanned spacecraft for NASA. JPL-run projects include the Galileo Jupiter mission and the Mars rovers, including the 1997 Mars Pathfinder and the twin 2003 Mars Exploration Rovers. ...
GeoTIFF represents an effort by over 160 different remote sensing, GIS, cartographic, and surveying related companies and organizations to establish a TIFF based interchange format for georeferenced raster imagery.
GeoTIFF Revision 1.0 Specification: This is the official release version of the GeoTIFF spec.
Parts 1, 2, 3 and 4 of a tutorial series by Daniel Denk on manipulating geotiff files primarily with regard to photoshop.
The GeoTIFF tags and definitions are considered completely "orthogonal" to the baseline and extended TIFF tag definitions currently supported in TIFF V 6 by Adobe/Aldus.
GeoTIFF merely expands this to involve public domain tags and structures that are interoperable between any GIS.
GeoTIFF has been proposed to the Open GIS Consortium, for example, and other entities are evaluating whether GeoTIFF should be proposed to international or other standards groups.
