GPS 4-H: USING THE GLOBAL POSITIONING SYSTEM IN 4-H PROGRAMMING MIKE CLIFFORD
GPS WOULD HAVE SAVED HIM !!!
Global Positioning System A network of satellites that continuously transmit coded information, which makes it possible to precisely identify locations on earth by measuring distance from the satellites.
THE GPS SATELLITE CONSTELLATION
From GPS Land Navigation by Michael Ferguson
GPS and GIS DEFINITIONS GPS is short for Global Positioning System which is "a network of satellites that continuously transmit coded information, which makes it possible to precisely identify locations on earth by measuring distance from the satellites". Of course, many users also refer to their hand-held GPS receivers as "my GPS" ... as in the statement "my GPS' batteries went dead and I got lost!" GIS is short for Geographic Information System(s). "In the strictest sense, a GIS is a computer system capable of assembling, storing, manipulating, and displaying geographically referenced information , i.e. data identified according to their locations. Practitioners also regard the total GIS as including operating personnel and the data that go into the system" ( from: http://www.usgs.gov/research/gis/title.html ).

World Geodetic System 1984 Default datum on Garmin and most other GPS receivers. Most accurate datum, but not yet in wide use on maps.
❧ NAD27 (NAD27CONUS) North American 1927 Older datum used on most USGS topographic maps. (We will be using this datum for the workshop)
❧ NAD83
North Amerian Datum 1983 Very similar to WGS84. Used on newer USGS maps. ●

Compass Only 1. Select an on-route landmark. Hold compass level and point the Direction of Travel Arrow at the landmark. 2. Find your heading to the landmark by turning compass dial until the N aligns with the Red end of the Needle. Read heading at the Index Line. 3. Keep the Needle aligned with the N. Sight and move toward your landmark. Repeat procedure until you reach your destination.

Compass & Heading 1.
When given a heading in degrees, turn the Dial so the heading is set at the Index Line. Hold compass level with the Direction of Travel Arrow pointing straight ahead.
2.
Turn your body until the Red end of the Needle is aligned with the N on the Dial.Travel in this direction.
3.
Pick out a landmark in line with your heading. Move toward it. Repeat procedure until you reach your destination.
Compass & Map Hold the compass level in front of you with the Direction of Travel Arrow pointing straight ahead. Turn your body until the Red end of the Needle is directly over the Red Orienting Arrow. Look up. Find a landmark. Move to it. Repeat until you reach your destination. 1. Place compass on map with baseplate edge connecting where you are (start “A”) and where you want to go (finish “B”). 2. Turn the compass Dial until the N aligns with Magnetic North (MN) on map. 3. Hold the compass level in front of you with the Direction of Travel Arrow pointing straight ahead. Turn your body until the Red end of the Needle is directly over the Red Orienting Arrow. Look up. Find a landmark. Move to it. Repeat until you reach your destination.
