0SRM

In order to get OSRM data, you need to download the California Open Street Map data and then process it using OSRM. The OSRM process can happen either in docker or using the nodeJS binding libraries.

Setup

DOCKER (optional): Get the docker image:

docker pull osrm/osrm-backend

NodeJS:

npm install @project-osrm/osrm

Next, in some folder grab the California OSM data:

curl -O https://download.geofabrik.de/north-america/us/california-latest.osm.pbf

Make sure you have enough RAM available to docker if you are going to use it. I used 16GB. See: https://docs.docker.com/docker-for-mac/#memory.

Profile

OSRM needs a vehicle transportation profile to run. By default they include examples such as car or bicycle. We are using a special forestry profile. Whatever profile you use, pass it in during the first step below. It needs to be in the correct node_modules directory to run.

Process OSM files

NodeJS:

node_modules/@project-osrm/osrm/lib/binding/osrm-extract data/california-latest.osm.pbf -p node_modules/@project-osrm/osrm/profiles/forestry.lua

node_modules/@project-osrm/osrm/lib/binding/osrm-contract data/california-latest

See https://github.com/Project-OSRM/osrm-backend/blob/master/docs/nodejs/api.md for more details. This seems to be the easiest method, but an officially recommended docker method is also provided below.

docker run -t -v "${PWD}:/data" osrm/osrm-backend osrm-extract -p /opt/car.lua /data/california-latest.osm.pbf

docker run -t -v "${PWD}:/data" osrm/osrm-backend osrm-partition /data/california-latest.osrm

docker run -t -v "${PWD}:/data" osrm/osrm-backend osrm-customize /data/california-latest.osrm

This should give you a directory full of *.osrm.* files which you can use with the OSRM JS library.
