[sumo-user] About the astar algorithm landmark

[g2121044 <g2121044@xxxxxxxxx>]

Hello

I have a question about the astar algorithm.
In the reference it says that I can generate lookuptable data based on landmark data and use it for astar.
https://sumo.dlr.de/docs/Simulation/Routing.html#routing_algorithms

Do I have to create this landmark data by myself?
Is there a function to generate it automatically from net.xml?
Sorry to bother you again.

Best regard,
Nishikawa
