WHAT IS GPS?
• Satellite based radio positioning system
• Developed and maintained by the U.S. Department of Defense
• Made up of three segments:SpaceControlUser or Ground receivers
• Used for obtaining accurate locations any where on earth

The Right Datum is Important!
GPS data stored in WGS84/NAD83 datum and displaying them with GIS data in NAD27 datum can result in 100's of meters in error!

What is Geocaching?What is Geocaching?
Geocaching is a worldwide “scavenger hunt” using GPS to find “caches” of treasure. The only rules are to leave something if you take
something and do not disturb the cache
