The GeoTIFF format is an extension of the TIFF (Tagged Image File Format) format. The TIFF format is an image file format that allows tags to be added in the file, tags being information about the image contained in the file such as the resolution, the number of samples per pixel, and so on. The GeoTIFF extension adds specific cartographic tags that give geographic information about the image contained in the file, such as the coordinate system in which the image is represented and the location of the image in this coordinate system.
