GeoTIFF is a public domain metadata standard which allows georeferencing information to be embedded within a TIFF (Tagged Image File Format) file. This means that geographic information, such as coordinate systems, map projections, datums, and other georeferencing details, are stored directly within the image file itself. This eliminates the need for separate 'world files' or other auxiliary files to define the spatial location of the image data. GeoTIFF is widely used in geographic information systems (GIS), remote sensing, photogrammetry, and other geospatial applications. It supports a wide range of raster data types, including imagery, elevation data, and thematic maps. The format is designed to be flexible and extensible, allowing for the storage of various types of geospatial metadata. GeoTIFF files are often used for storing aerial imagery, satellite imagery, digital elevation models (DEMs), and other types of geospatial raster data. The ability to store georeferencing information directly within the image file makes GeoTIFF a convenient and efficient format for exchanging and managing geospatial data.
