Lab 1: Accuracy of a Handheld GPS Device

The average waypoint was 3.8 meters away from the reference waypoint. There was difference of 5.9 meters in elevation between the reference and the average. The average waypoint was at a  higher elevation. It seems as though the device was more precise horizontally than it was vertically.
Accuracy is based on a device measuring something and getting a result that truly reflects the situation. Accurate results have low to no error. Precision is a low variability between  measurements. Precise measurements would cluster around a point while imprecise ones would be found anywhere.
