What is GPS Tagging on a Camera

GPS for (almost) every camera

Do you know the problem? You find a photo in your image archive and ask yourself:

"Where did I take this?" The solution is called geotagging.

This article is intended to illustrate how, with which software and which devices you can assign latitude and longitude of a place to your photos and so never again forget where you took a photo. The possible uses of photos with geospatial data are huge. They range from optimized image searches to complex presentations with additional effects. And when the pictures are published in photo communities such as Flickr, Locr, or Google Earth, you and the community members can follow your photo forays precisely across the world. Here is how to do it!

This is how geotagging works:

Geotagging adds additional information about the location to digital photos. Other terms that are used as synonyms are "georeferencing", "geocoding", "localization", or "geo-imaging".

There are various methods of inserting location information into the metadata of a photo. They are divided into direct, manual and indirect types of geotagging. In our shop we offer solutions for both direct and indirect geotagging.

Direct - in-camera geotagging:

Here, geographic information is written into the Exif data directly from the camera when the picture is taken. This variant is most widespread in smartphones. Meanwhile, a number of compact cameras and a few digital SLR cameras also offer this feature integrated. External GPS receivers are also available for many DSLRs. The great advantage of this variant is that the Exif data does not have to be subsequently revised or changed, i.e. no rework on the computer is necessary. The following example shows how photo archiving with located images can look. Here illustrated with geosetter:



We have solutions for numerous Nikon and Canon DSLRs ready for you and after numerous tests we are convinced that we have the best geotaggers in our range for you.

Manual geotagging:

A location is assigned to a photo from a map. This variant is possible with the help of software that uses map material (e.g. Geosetter). Unfortunately, the assignment is usually only possible individually, so reworking many photos requires a little time. However, with this variant it does not matter whether the location where the picture was taken had GPS reception or not.

Indirect - track-based geotagging:

The position values ​​are automatically assigned to the recordings from a recorded GPS track (travel route). In addition to the GPS file, you need the appropriate software for this. As long as the time difference between the camera and the GPS receiver is sufficiently consistent, this is a very precise type of location, as pure GPS receivers are usually a little more precise than geotaggers. However, a certain amount of reworking on the computer is necessary here too.

In our shop we offer solutions for both direct and indirect geotagging.
