Claim 0:
1. A remote navigation device configured to communicate with a navigation terminal, comprising:
at least one storage medium including a set of instructions for generating a road map; and
at least one processor in communication with the storage medium, wherein when executing the set of instructions, the at least one processor is directed to:
obtain a navigation route for the navigation terminal and a current location of the navigation terminal;
obtain road network data associated with the current location of the navigation terminal based on the navigation route and the current location of the navigation terminal, wherein the road network data includes a plurality of links and a plurality of nodes, wherein each of the plurality of nodes is connected to one or more links, the one or more of links including at least one type of links;
determine a level for each of the plurality of nodes;
for each of the plurality of nodes, determine one or more target links for the at least one type of links connected to the node based on the level of the node; and generate a road map based on the target links, wherein to determine the one or more target links for one type of links connected to the node based on the level of the node, the at least one processor is further directed to:

determine whether the level of the node is the first value; and
in response to the determination that the level of the node is the first value, determine all of the type of links connected to the node as the target links.
