In the offline planning guide, I read:
GraphHopper
Offline routing requires graphs (folders of routing data):
- We provide offline graphs for most regions of the world in our download server (like offline maps).
- Unpack the downloaded
.zip
file on your smartphone and load the graph via Kurviger menuRouting | Open data
.
Does that mean we have to select the entire folder, for instance ‘Germany’, or just a single file in this folder, like 'location_index" to load the graph?
