Display photo geotag information on map12/25/2023 ![]() See JOSM/Photomapping if you want the photos to display in the proper location in JOSM, or see Geotagging Source Photos if you want to add geo-tags to photos that don't have them. Digital cameras add the date and time to each photo (in the EXIF data), and a GPS tracklog will allow you to correlate by time, matching up the photos to the exact position they were taken. What if you're using a camera without GPS? You might work with two separate gadgets, a camera and GPS unit. Tools such as JOSM will generally use this geolocation metadata. This is very easy with a smartphone, although you may need to enable it. Smartphones and some cameras come with in-built GPS (and some GPS units come with in-built camera) so these devices will typically write geolocation data to the image file's metadata (EXIF) each time the shutter is snapped. You can also work out orientation using the angle of the sunlight in the pictures. Pretty low-tech, but sufficient most of the time. You can develop your own tricks to solve these problems, but here's one approach: Simply rotate the camera: landscape pictures for what's ahead, portrait-size for infos about the way you just came from and a rotation of +/- 45° for what is on the right/left of the road. If an area of one photo is visible in the previous photo, it makes it easier to orientate when you're looking back over them.Įven if you have a GPS track, it can be difficult to determine the way you were facing when taking a photograph. Also the more photos you take the better. To aid your memory it's always a good idea to input map data as soon as possible after collecting it. You'll need to remember the path you walked and the direction you were facing when you took the photos. This is particularly true if you're in an area with good bing coverage (makes it a lot easier to get things in the right place) and if you have a good memory for this kind of thing. You don't need to use GPS and other advanced tricks described on this page. Use your camera to help you remember stuff. 6 Websites/projects about geolocating photos.
