Abstract: According to one aspect, a method includes obtaining at least a first map from at least a first map source on a first map arrangement, processing the at least first map to generate a first set of data, and providing the first set of data to a vehicle, wherein the vehicle includes an autonomy system and at least one sensor. The method also includes obtaining a second set of data from the at least one sensor, and processing the first set of data and the second set of data using a second map arrangement, the first map arrangement and the second map arrangement forming a map engine arrangement, wherein processing the first set of data and the second set of data causes a high definition (HD) map to be generated.

Abstract: According to one aspect, a method includes obtaining sensor data from a plurality of sensors onboard a vehicle, and obtaining prior map data from a server that is offboard with respect to the vehicle. The method also includes processing the sensor data using a first arrangement onboard the vehicle to generate processed sensor data, and generating an inferred context map using a map prediction arrangement located onboard the vehicle, wherein generating the inferred context map includes processing the processed sensor data and the prior map data using the map prediction arrangement.
