Types of GPS |
There are three broad classes of application - road, hiking and maritime - and each is further subdivided into other types which offer different features depending on the exact use to which they will be put and the environment that they will be operating in. In-car (or in-vehicle) GPS need to be reasonably accurate, reliable, and contain details of all the roads, and important addresses (gas stations, railroads etc.) and points of interest for the region in which the device will be operating. These devices may be part of the in-vehicle entertainment system, which ties them to a single vehicle.
Portable devices suitable for in-vehicle use exist, and offer a great alternative to those which are integrated within a particular vehicle. Maritime units need very specific features, not least being that they should be waterproof, and containing additional information that can be plotted on nautical charts. Their maps are also very specific, giving undersea elevations as well as navigable channel information. This includes devices such as fishfinders, which build other fishing related features into the basic GPS unit. A fishfinder is very useful for positioning, tracking and helping the fishing enthusiast to locate schools of fish at sea. |
