Router API

Offers an unified API for multiple routers based on countries distribution and other parameters like means of transport. Build in Ruby with a Grape REST swagger API.

API

The API is defined in Swagger format at http://localhost:8082/0.1/swagger_doc and can be tested with Swagger-UI https://petstore.swagger.io/?url=https://localhost:8082/0.1/swagger_doc

Capability

Retrieve the available modes (eg routers) for APIs by GET request.

http://localhost:8082/0.1/capability.json?&api_key=demo

Returns JSON:

{
  "route": [
    {
      "mode": "mode1",
      "name": "translation1",
      "area": []
    },
    {
      "mode": "mode2",
      "name": "translation2",
      "area": []
    },
    {
      "mode": "mode3",
      "name": "translation3",
      "area": [
        "Area1", "Area2"
      ]
    }
  ],
  "matrix": [],
  "isoline": []
}

Route

Return the route between list of points using GET request.

For instance, route between Bordeaux, Mérignac and Talence

http://localhost:8082/0.1/route.json?api_key=demo&mode=osrm&geometry=true&loc=44.837778,-0.579197,44.844866,-0.656377,44.808047,-0.588598

Returns GeoJSON:

Docker

Copy and adjust environments files.

cp ./config/environments/production.rb ./docker/

Create a .env from .env.template, and adapt if required. Enable components in COMPOSE_FILE var. Only required for non external engines.

Build docker images

docker-compose build

Launch containers

docker-compose up -d

Without Docker

Install package containing ogr2ogr bin as system package (GDAL).

In router-api as root directory:

bundle install

bundler exec puma -v -p 8082 --pidfile 'tmp/server.pid'

And in production mode:

APP_ENV=production bundle exec puma -v -p 8082 --pidfile 'tmp/server.pid'

Available production extra environment variables are:

REDIS_HOST=example.com

Backends

OTP

cd docker/otp
./otp-rebuild-all.sh
# OR
./otp-rebuild.sh bordeaux

The script will build bordeaux graph from ./otp/data/graphs in /srv/docker

OSRM

Init landuse database

docker-compose -f docker-compose-tools.yml exec postgis bash -c "\\
  psql -U \${POSTGRES_USER} -w \${POSTGRES_PASSWORD} -c \"
    CREATE TABLE urban (gid serial, code int4);
    ALTER TABLE urban ADD PRIMARY KEY (gid);
    SELECT AddGeometryColumn('','urban','geom','0','MULTIPOLYGON',2);
    ALTER TABLE urban ALTER COLUMN geom TYPE geometry(MultiPolygon, 4326);
    CREATE INDEX urban_idx_geom ON urban USING gist(geom);
  \"
"

Load a shapefile. See below how to get shapefile.

docker-compose -f docker-compose-tools.yml up -d postgis
docker-compose -f docker-compose-tools.yml exec postgis bash -c "\\
    apt update && apt install -y postgis && \\
    shp2pgsql -a /landuses/urban.shp | psql -U \${POSTGRES_USER} -w \${POSTGRES_PASSWORD} \\
"

Alternatively, for test purpose only, add just one record into the table

docker-compose -f docker-compose-tools.yml exec postgis bash -c "\\
  psql -U \${POSTGRES_USER} -w \${POSTGRES_PASSWORD} -c \"
    INSERT INTO urban (code, geom) VALUES ('1', NULL);
  \"
"

Landuse database from "Corine Land Cover"

Download GeoPackage from Copernicus into the landuses directory. Double unzip.

Convert the data

ogr2ogr -sql "SELECT * FROM (SELECT CASE CODE_18 WHEN 111 THEN 1 WHEN 112 THEN 2 WHEN 121 THEN 2 WHEN 123 THEN 2 WHEN 124 THEN 2 WHEN 511 THEN 5 WHEN 512 THEN 5 END AS code, Shape FROM U2018_CLC2018_V2020_20u1) AS t WHERE code is NOT NULL" -t_srs EPSG:4326 urban.shp U2018_CLC2018_V2020_20u1.gpkg

Landuse database from OSM

Download an .osm.pbf file. Eg. with Morocco

osmium \
    tags-filter \
    --overwrite -o morocco-landuse.osm.pbf \
    morocco-latest.osm.pbf \
    wr/landuse=residential,retail,railway,industrial,garages,construction,commercial,cemetery,village_green,religious,education \
    wr/building!=no

# Use meter unit, eg UTM zone
ogr2ogr \
    -t_srs EPSG:32629 \
    morocco-landuse.gpkg \
    morocco-landuse.osm.pbf \
    multipolygons

# Over simply approach, but it works
ogr2ogr \
    morocco-landuse-union.gpkg \
    -dialect spatialite -sql 'SELECT ST_Union(ST_Buffer(geom, CASE WHEN landuse IS NOT NULL THEN 100 ELSE 50 END, 1)) AS geom FROM multipolygons' \
    -explodecollections \
    morocco-landuse.gpkg
ogr2ogr \
    -t_srs EPSG:4326 \
    morocco-urnan.shp \
    -dialect spatialite -sql 'SELECT 2 AS code, ST_Simplify(geom, 20) AS geom FROM "SELECT" WHERE ST_Area(ST_Simplify(geom, 20)) > 30000' \
    -explodecollections \
    morocco-landuse-union.gpkg

Generate Low Emission Zone GeoJSON

Add the file at docker/osrm/low_emission_zone.geojson.

Build the graph

docker-compose -f docker-compose-tools.yml up -d postgis
docker-compose -f docker-compose-tools.yml up -d redis-build
docker-compose run --rm osrm-car-iceland osrm-build.sh

After the build process postgis and redis-build could be stoped.

docker-compose -f docker-compose-tools.yml exec redis-build redis-cli SAVE
docker-compose -f docker-compose-tools.yml down postgis
docker-compose -f docker-compose-tools.yml down redis-build
