To steal a definition from Wikipedia:
Geotagging is the process of adding geographical identification metadata to various media such as photographs, video, websites, SMS messages, or RSS feeds and is a form of geospatial metadata. These data usually consist of latitude and longitude coordinates, though they can also include altitude, bearing, distance, accuracy data, and place names. It is commonly used for photographs, giving geotagged photographs.
I have owned a GPS data logger for since December 2008, but it has taken me until now to get around to geotagging my photos.
The device I have is a “Qstarz GPS Travel Recorder: BT-Q1000 Platinum” which is pretty basic, and the software isn’t that good for tagging photos. As a result, I have come up with a better way of doing things.
