1. A method for generating an improved database representing a road network, comprising the steps of:

  • defining a baseline road in the road network, the defining comprising replacing an original representation of the baseline road in the database with new data, the new data having a greater accuracy than the original representation;

    collecting the new data from a vehicle traveling a route in the road network;

    dividing the route into one or more route segments;

    assigning each route segment as an on-baseline segment, an off-baseline segment, an off-baseline to on-baseline transition, an on-baseline to off-baseline transition, or a within-baseline transition;

    processing the collected data for each route segment.
