Abstract
A method is disclosed for obtaining altitude-related data along roads. A vehicle includes equipment capable of determining the current absolute positions of the vehicle as it is being driven. The vehicle also includes equipment capable of determining a distance traveled by the vehicle. Two points along a road are selected. Altitude-related data are determined as a function of the horizontal difference between the absolute positions of the two points and the distance traveled by the vehicle between the two points.
