when an aircraft or operator is targeting an area, the position is inaccessible (for example over a valley or wetland), there are personal health & safety concerns (motorway traffic), or the user wants to quickly capture multiple targets from a single, safe position (trees, street signage and furniture). Civilian integrated GPS cameras with rangefinders and remote standoff capability are currently available made by manufacturers such as Ricoh and Surveylab. Uses When geotagged photos are uploaded to online sharing communities such as Flickr, Panoramio or Moblog, the photo can be placed onto a map to view the location the photo was taken. In this way, users can browse photos from a map, search for photos from a given area, and find related photos of the same place from other users. Many smartphones automatically geotag their photos by default. Photographers who prefer not to reveal their location can turn this feature off. Additionally smartphones can use their GPS to geotag photos taken with an external camera. Geotagged photos may be visually stamped with their GPS location information using software tools. A stamped photo affords universal and cross-platform viewing of the photo's location, and offers the security of retaining that location information in the event of metadata corruption, or if file metadata is stripped from a photo, e.g. when uploading to various online photo sharing communities. Geotagging is also being used to determine social patterns. For example, Now app uses geotagged Instagram photos to find nearby events happening now. Formats With photos stored in JPEG, TIFF and many other file formats, the geotag information, storing camera location and sometimes heading, is typically embedded in the metadata, stored in Exchangeable image file format (Exif) or Extensible Metadata Platform (XMP) format. These data are not visible in the picture itself but are read and written by special programs and most digital cameras and modern scanners. Latitude and longitude are stored in units of degrees with decimals. This geotag information can be read by many programs, such as the cross-platform open source ExifTool. An example readout for a photo might look like: GPS Latitude : 57 deg 38' 56.83" N GPS Longitude : 10 deg 24' 26.79" E GPS Position : 57 deg 38' 56.83" N, 10 deg 24' 26.79" E or the same coordinates could also be presented as decimal degrees: GPS Latitude : 57.64911 GPS Longitude : 10.40744 GPS Position : 57.64911 10.40744 When
