While read the source code of https://github.com/graphhopper/map-matching , i notice it is hard to understand the structure of file location_index and the relationship between it and edges 、nodes , so is there doc which describe the structure and relationship for that ? Many thanks .
See our documentation: https://github.com/graphhopper/graphhopper/tree/master/docs like the more technical: https://github.com/graphhopper/graphhopper/blob/master/docs/core/technical.md
Got it， thanks for your so quick reply！
