Furthermore, it is possible ( the Nikon GP-1 approximately ) to connect a GPS receiver directly to the camera body; the camera stores the position data in the Exif field of image files in RAW or JPEG format, allowing georeferencing of the images.

Also, the " guide mode " has been extended: it shows the user when taking possible steps to improve the settings for the scene, so that the user is introduced to the use, without prior knowledge in photography.

GPS capability

The D3100 has a combined interface for cable release and a GPS receiver such as the Nikon GP-1 to allow for easy geotagging of JPEG and NEF files. The GPS interface processes in addition to the GPS data and compass information ( Heading). This function is only used by Geotagger third party.
