How to Navigate?

I divide GPS navigation into two-dimensional vehicle navigation, foot navigation, and path navigation. Two dimensional vehicle navigation applies to steering a vehicle such as an airplane or a boat where the GPS is used for a steering reference.

Path navigation is where the GPS is used to orient and provide progress along a route such as boating along a river or traveling along a road or trail. However, in path navigation the GPS is not actually used for steering guidance. The sides of the road or banks of the river provide guidance.

Furthermore, there is a slight variation in using GPS for foot navigation. One of the biggest advantages of GPS is that it provides information on the direction that you are traveling. This is unique in that most systems in the past have only provided information on the direction that a vessel is pointing. Due to currents and winds, there is often a significant difference. However, often during foot navigation the GPS is unable to provide direction of travel. Thus, there is a difference in navigation technique.
