A process and system for collecting data about roads located in a geographic area and using the collected data to develop representations of the locations and geometry of the roads for a geographic database. A vehicle in which data acquisition equipment is installed is driven on the roads. Using the data acquisition equipment, data are collected representing positions of the vehicle as it is being driven along the roads and data indicating the path of the vehicle as it is being driven along the roads. The data acquired while traveling may be smoothed and fused. The data acquired while traveling are processed by a program that automatically selects which of the data are necessary to provide a specified level of accuracy in a geographic database that includes data that represent the roads including data that represent positions and geometry of the roads. The data selected by the program are stored in the geographic database.

Method and system for automatic generation of shape and curvature data for a geographic database

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.
