# Prereqs: cmake, g++, make, >=12GB RAM for extract, >=10GB disk.

|
|
# The PBFs are pre-downloaded in ../osm/ (us-new-hampshire, us-connecticut,

# us-massachusetts, us-new-york .osm.pbf, from the geofabrik mirror on
|

# HuggingFace: NoeFlandre/osm-geofabrik-raw-pbf-extracts).

#
|
|
# Artifacts go to ../osm/build/. Router ends up on http://localhost:5000.
