Tracking altitude, speed, and course

In this section, we will discuss the different types of location information that are provided by the GeoCoordinateWatcher and how they might be used. A quick look at the Object Browser shows us that the GeoCoordinate object has several interesting properties:

In addition to Latitude and Longitude, there is Altitude, Speed, and Course, among others. Altitude and Speed are pretty self-explanatory, but Course might not be as obvious. Course is your heading or the direction you are going, given two points. The following table shows each property and its unit of measurement:

Property	Unit of measure
Latitude	Degrees (-90.0 to 90.0)
Longitude	Degrees (-180.0 to 180.0)
Altitude	Meters
Speed	Meters per second
Course	Degrees (0.0 to 360.0)
Horizontal/Vertical Accuracy	Meters

Horizontal and Vertical Accuracy specifies the accuracy of Latitude/Longitude and Altitude, respectively, in meters. For example, this means your actual Latitude position...
