[GraphHopper] About Intermediate Data

[Peter K]

Hey n  Pengzhan Hao,

the graph files are (mostly) independent from the algorithm, they are
just used to avoid the costly reparsing of the OSM file everytime you
restart GraphHopper. The only difference is that CH creates some
additional edges, so called shortcuts.

The graph is organized as described here:

Regards,
Peter.
