Geocaching (/ ˈ dʒ iː oʊ k æ ʃ ɪ ŋ /, JEE-oh-KASH-ing) is an outdoor recreational activity, in which participants use a Global Positioning System (GPS) receiver or mobile device and other navigational techniques to hide and seek containers, called geocaches or caches, at specific locations marked by coordinates all over the world. [2]
[3] [4] On Geocaching.com, each travel bug has an individual page which tracks its movement and calculates the distance travelled. [5] Travel bugs move from cache to cache by Geocachers picking up the bug and physically moving them. There is no obligation to pick up a bug from a cache as Geocachers can simply "discover" the bug on the website.
Geohashing / ˈ dʒ iː oʊ ˌ h æ ʃ ɪ ŋ / is an outdoor recreational activity inspired by the webcomic xkcd, in which participants have to reach a random location (chosen by a computer algorithm), prove their achievement by taking a picture of a Global Positioning System (GPS) receiver or another mobile device and then tell the story of their trip online.

GeoKrety (from Greek: geo, "earth" and Polish: krety, "moles") is an online tracking service targeted at Geocachers.Each registered object, called a GeoKret (plural: GeoKrety), has a unique tracking code, allowing its movements between locations such as Geocaches to be tracked and registered on the service.
The core functionality added by a spatial extension to a database is one or more spatial datatypes, which allow for the storage of spatial data as attribute values in a table. [4] Most commonly, a single spatial value would be a geometric primitive (point, line, polygon, etc.) based on the vector data model .
