X Marks the Spot

Add location data to your best digital images with digiKam and GPS Correlate.
Many image formats let you store the GPS coordinates for the image location as metadata. Storing location data with the image makes it easy to document where the image was taken. Some mapping tools will even let you plot the geotagged images on a map; you can click an icon on the map and see what the view was like from that location.
Most smartphones, which typically have built-in GPS capabilities, automatically add location data to captured images. But conventional digital cameras, even many premium cameras, don't have a way to sense and record GPS data.

A GPX track is a log of coordinates from a recent hike or road trip. Turn on GPS tracking on your smartphone or GPS device, then start walking or riding. The device will record the data as a track that you can then display using a mapping tool.
