First Claim
Patent Images
1. A method of obtaining altitude-related data along roads, the method comprising the steps of:
- traveling along roads in a vehicle;
determining a first absolute position of the vehicle at a first position along one of the roads;
determining a second absolute position of the vehicle at a second position along one of the roads; and
determining altitude-related data as a function of a horizontal difference between the first absolute position and the second absolute position and a distance traveled by the vehicle between the first position and the second position.

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.
