GeoTIFF is a public domain TIFF-based raster geospatial image file format. It is a metadata standard that allows a GeoTIFF file to store georeferencing information within the file itself. This georeferencing information describes the map projection, coordinate system, and the extent of the image data, enabling GIS software to correctly display and analyze the image in its proper geographic location.

The GeoTIFF standard was developed to extend the capabilities of the TIFF (Tagged Image File Format) for use in geographic information systems. TIFF is a widely used format for storing raster images, but it does not inherently contain any information about the geographic coordinates or projection of the image. GeoTIFF adds specific TIFF tags that convey this crucial spatial data. These tags can include information about the model tie points, raster space, geographic latitude/longitude, and projection information.

GeoTIFF files are commonly used for storing aerial photography, satellite imagery, digital elevation models, and other types of geographically referenced raster data. They are supported by a wide range of GIS software, including ESRI ArcGIS, QGIS, and GDAL/OGR. The ability to embed georeferencing information directly into the file makes GeoTIFF a convenient and popular format for sharing and using geospatial raster data. Its open standard nature ensures broad compatibility and accessibility across different platforms and applications.
