An introduction to GPS, GIS and its uses in Agriculture
GPS (Global Positioning System):
Global Positioning System (GPS) is a satellite based navigation system that can provide people who use it with their exact position on Earth, tell them how to get to another location, how fast they are moving, where they have been, how far they have gone, what time it is, and many more.
GPS was originally designed to help the U.S. military with finding the accurate location of their soldiers, vehicles, planes and ships around the world. For more: Click Here>>>
