Abstract
A process and system for collecting data about roads located in a geographic area and using the collected data to develop representations of the roads for a geographic database. Data representing positions along roads are acquired using equipment installed in a vehicle which is driven on the roads. The data acquired while driving may be smoothed and fused. The data acquired while driving are processed by a program that automatically determines new coordinates to adjust the represented positions to align with the centerlines of the represented roads. Data including the new coordinates are stored in the geographic database.
