Abstract

An approach is provided for creating a road geometry representation (e.g., a base map with double digitized roads representing actual travel paths and connectivity). The approach involves, for example, retrieving probe data collected from sensors of probe devices traveling within a geographic area including at least one geographic partition. The approach also involves dividing each of the at least one geographic partition into grid cells. The approach further involves detecting directional groupings of the probe data for each grid cell. The directional groupings comprise probes of the probe data that share a respective common travel direction. The approach further involves determining a density maxima location of the probes sharing the respective travel direction, for said each grid cell and each directional grouping. The approach further involves creating a continuous road path based on the density maxima locations for the grid cells. The approach further involves including the continuous road path in an output representing a base map of the geographic area.
