It is also possible to connect a GPS receiver (such as the Nikon GP-1 ) directly to the camera housing. The camera saves the position data in the Exif area of ​​the image files in RAW or JPEG format, thus enabling georeferencing of the images. In addition to the GPS data, the GPS interface also processes compass information ( heading ). This function can be used with accessories from third-party manufacturers.
