Links to GPS Sites on the WWW

There is plenty of additional information about the GPS on the WWW. In fact, you may easily lose yourself among the many sites which cater to a broad public at many different levels of complexity.

Before you start exploring on your own hand, you may like to have a look at the sites below. Most of them have very useful onward links:

Dana (Department of Geography, University of Texas at Austin, USA) - Selected as the "Best GPS Site", one of GIS World's "Best of the Net" sites for 1996.
