Maps & GPS - Scott's Little Corner of the Web

How GPS receivers work - very good, yet understandable explaination.
Maporama - not the best map service on the net, but it will return coordinates (Lon/Lat) when you input a street address.

Notes:
For Latitude:
1° = 69.047 statute miles or 60 nautical miles
1' = 1.15 miles or 6076.11549 feet or 1 nautical mile
1" = 101.26859 feet
The above holds true for Longitude at the Equator.

Geocaching

Are you wondering what geocaching is (pronounced "geo-cashing") and how does it work? Geocaching is a new rapidly growing sport that is essentially a high-tech treasure hunt. Geocachers use a GPSr (global positioning system receiver) to help locate a hidden cache (the "treasure") which has known coordinates, and lies hidden somewhere in the outside world. The coordinates are posted on a central website (www.geocaching.com) and geocachers can search for cache locations using zip codes, regions, or city names. Once they’ve identified their destination, they use a GPSr to get them there. A handheld GPS device (starting at about $100) looks approximately like a small cell phone and reads signals from several orbiting satellites, allowing users to determine their coordinates anywhere in the world to within a few feet. The caches, or treasure boxes, are typically small weatherproof containers like ammo boxes or Tupperware containers, and they usually contain a logbook, a pencil, and a handful of trinkets. The idea is to find the cache, sign the logbook, and if you take something you should leave something behind. It is great fun and the best part of it is usually the hunt.
