Abstract

Provided herein is a method of generating low bandwidth map format agnostic routes between origins and destinations for route communication between different map formats or versions using reduced bandwidth. Methods may include: receiving one or more intermediate segment anchor points and encoded server-provided route fragments for a requested route between an origin and a destination; identifying one or more intermediate segments corresponding to the one or more intermediate segment anchor points; generating a route between the origin and the destination, the route including the one or more intermediate segments and a plurality of client-generated route fragments; encoding each client-generated route fragment by application of an XOR algorithm to the client-generated route fragment road segments; comparing the encoded client-generated route fragments to the encoded server-provided route fragments; and providing navigational assistance for traveling along the route in response to the encoded client-generated route fragments corresponding with the encoded server-provided route fragments.
