Abstract
A method and system are provided for developing geospatial information concerning a particular area using a plurality of uncoordinated probe vehicles moving in the area. The probe vehicles are equipped with a position determining system and gather probe vehicle specific geospatial information as the vehicles move in the area. This probe vehicle specific information is combined over time into a data set. A central processor analyzes the data set to determine geospatial information having a higher quality than that gathered by the individual probe vehicles for the particular area.
