the GPS

GPS Basics
The Federal Aviation Administration has posted a brief introduction to the US Global Positioning System. The site also contains information about the WAAS.

GeoCaching
The GPS has spawned a new form of recreation - GeoCaching. According to the werbsite, GeoCaching is basically an adventure game for GPS users. The basic idea is to have individuals and organizations set up caches all over the world and share the locations of these caches on the internet. Once found, a cache may provide the visitor with a variety of rewards.

Tasmanian GeoCaching
Next time you need to layover in Tasmania, logon this website and join the international group of Tassie cachers.

Metadata

Federal Geographic Data Committee
A metadata record is a file of information, usually presented as an XML document, which captures the basic characteristics of a data or information resource. It represents the who, what, when, where, why and how of the resource. Geospatial metadata commonly document geographic digital data such as Geographic Information System (GIS) files, geospatial databases, and earth imagery but can also be used to document geospatial resources including data catalogs, mapping applications, data models and related websites.
