MAPLETS FOR MAINTAINING AND UPDATING A SELF-HEALING HIGH DEFINITION MAP

An apparatus is onboard a vehicle and in communication with sensors onboard the vehicle. The apparatus receives a maplet request identifying a request region; and, responsive to determining that the vehicle is within the request region, processes sensor data captured by sensors to generate a multi-sensor data stream corresponding to a segment of a road network. The apparatus identifies an observation corresponding to a roadside barrier within the multi-sensor data stream; generates a maplet based on the observation and the maplet request; and provides the maplet such that a network apparatus receives the maplet. Generating the maplet comprises using a predetermined data model and a predetermined data format corresponding to a roadside barrier observation class to encode road data corresponding to an observation corresponding to a roadside barrier. The network apparatus is configured to validate/update map data of a digital map of the road network based on the maplet.
