Offline registration of elements between maps

A non-transitory computer-readable storage device including program instructions executable by one or more processors that, when executed, cause the one or more processors to perform operations, the operations comprising:

• obtaining a first map element from a first map, the first map element having a starting location and an ending location;
• matching the first map element to one or more second map elements from a second map;
• identifying a first point and a second point on the one or more second map elements from the second map, wherein the first point corresponds to the starting location of the first map element and the second point corresponds to the ending location of the first map element;
• defining registration information that identifies the first map element as corresponding to the one or more second map elements from the first point to the second point;
• storing the registration information for use in transferring information between the first map and the second map;
• transferring information from the first map to the second map using the registration information in response to a route request;
• generating a route in response to the route request using the second map and the information transferred from the first map to the second map;
• and
• performing one of:
• outputting a display of the second map and the route, or
• controlling an autonomous vehicle to travel toward a destination using the route.

A system, comprising:

• a memory;
• and
• a processor configured to execute instructions stored in the memory to:
• obtain a first map element from a first map, the first map element having a starting location and an ending location;
• match the first map element to one or more second map elements from a second map;
• identify a first point and a second point on the one or more second map elements from the second map, wherein the first point corresponds to the starting location of the first map element and the second point corresponds to the ending location of the first map element;
• define registration information that identifies the first map element as corresponding to the one or more second map elements from the first point to the second point;
• store the registration information for use in transferring information between the first map and the second map;
• transfer information from the first map to the second map using the registration information in response to a route request;
• generate a route in response to the route request using the second map and the information transferred from the first map to the second map;
• and
• perform one of:
• output a display of the second map and the route, or
• control an autonomous vehicle to travel toward a destination using the route.
