Abstract
A system and method identifies road features that may not appear on a map database, such as paths not described as roads on the map database, and whether all the roads at a crossing cross at the same grade level. The system and method may thus be used to identify points of departure from, or points of merging onto, a road described by the map database or a path identified as described herein, but not described by the map database.
