What is a "Mapping" GPS Receiver?

First, this article assumes you have at least a passing knowledge of what the Global Positioning System (GPS) is, and what a GPS receiver (GPSr) can do. You don't need to know how it works, only what it can do--which, in a nutshell, is to tell you where you are on or above the earth's surface, with the help of the GPS satellites in earth orbit. I'll be talking about the handheld GPS receivers generally used for recreational purposes such as hiking, geocaching, biking, car navigation, bench mark hunting, and so forth.
