GPS data: How to put your photos on the map

Photo files contain much more than just the picture. It also stores technical information about the recording, such as the camera model, exposure and time. But there is more: You can even save information about the location of the picture in the image file.

Most smartphone cameras do this automatically. With conventional digital cameras this works with special GPS devices. How to combine photos with the location data and then, for example, show your vacation route on a map, you can read in this guide.

How do the photos get on a card?

On the PC, you can display "localized" photos on a map using programs or Internet services such as Picasa web albums from Google, for example to track your travel route.

If you do not take photos with a smartphone, but with a conventional camera, you need a GPS tracker. Such "loggers" automatically save the current location data several times per minute with the respective time. The data then result in your route.

With smartphones, this route recording works with additional apps, for example the free "TrackRec". Then link geodata and photos with the "Geosetter" program.
