摘要

Process for producing a digital street map comprises producing positional data of a journey or of a vehicle in the form of coordinates of a coordinate network in a data bank, dividing the surface of the coordinate network into a number of squares of different dimensions, and determining the arithmetic mean of the geographic positional data for a square. Preferred Features: The vehicle's ID, journey direction and vehicle speed are stored.
