Abstract
Aspects of the disclosed invention relate to alignment of standard definition (SD) maps and high definition (HD maps) which may come from different sources. Responsive to input of a destination, a route to that destination may be defined, and SD map waypoints generated from that defined route. A graph may be generated from the HD map. The waypoints may be matched with nodes and edges in the graph. One or more edges may constitute a segment in the HD map. A plurality of segments are identified to match the route.
