There has been such a lot of buzz about Google Earth, Mapping Hacks, Location based services and Geo ‘Everything’, that I think it’s time for a quick list of definitions and related links to benefit those who are new to this field. Please feel free to add comments if I’ve missed anything, or you have a link to a better definition.

Please note: this post is regularly updated with new information, please check back again. If you would like to add something to the list, please comment. Last update 10th Nov 2005.

Geocaching

Geocaching is an outdoor sport that involves the use of a Global Positioning System (”GPS“) receiver to find a “geocache” (or “cache”) placed anywhere in the world. A typical cache is a small, waterproof container containing a logbook and “treasure”. Geocaching is a unique take on an earlier game called Letterboxing in that it uses two recent technologies, the GPS and the Internet. Participants are called geocachers.
