Abstract: The present application generally relates to methods and apparatus for inferring map data from GPS measurements. More specifically, the method and apparatus to receive a plurality of measurement data from vehicular GPS measurements and, optionally, additional sensor data. The system is then operative to generate latitude and longitude errors from the covariance matrix and apply this information to a plurality of measurement data in order to determine an actual location in response to the plurality of measurement data.
