Geotagging – or translated: geocoding – means that a photo is assigned a latitudinal and longitudinal position. Locr automatically links this data to your photos and displays the location where the photo was taken on virtual maps and satellite images. The location can be displayed on maps by Google Maps, Microsoft Virtual Earth or Yahoo Maps.
But there is more. Cumbersome labelling of photos is no longer necessary with georeferencing. Archiving and sorting photos is just as simple. Geotagging makes laborious searching for unlabelled photos a thing of the past. But how does geotagging work? You'll find the answer in the next section.
