TLocality Class Reference

class TLocality : public TCoordinate

Adds an error estimate for the horizontal and vertical accuracy of the point to TCoordinate. Accuracy information is held in a TReal32 and is measure in metres. The class also provides its own methods for determining the distance and bearing to a target point. These methods also provide an error estimate.
