pgrouting_osm

Requirements

TBD

See in the documentation of the pgrouting website for more informations: http://pgrouting.org

Download PBF OSM data from http://download.geofabrik.de/europe.html for your region of interest.
```
wget http://download.geofabrik.de/europe/great-britain-latest.osm.pbf
```
Download osm2po. I had originaly planned to use osm2pgrouting. See osm2pgrouting README in externals/osm2pgrouting, however due to memory requirements I have now opted for osm2po
```
wget http://osm2po.de/download.php?lnk=osm2po-4.9.1.zip
```
Unzip osm2po
Build/Setup your PostGres database with PostGIS installed.
There is a VagrantFile included to do a base build and a setup script used by vagrant which can be used if you want to build in a different way see Vagrant-setup/bootstrap_pg.sh
Use osm2po to convert the data for loading into postgres. You will need to accept the licence. More info on osm2po http://osm2po.de/
```
java -jar osm2po-4.8.8/osm2po-core-4.8.8-signed.jar prefix=gb great-britain-latest.osm.pbf 
```
This will create the SQL to load into postgres and start a local webservice for you test with.

Load the data into postgres from the route of the project run:

psql -U osmuser -d osm -W -q -f "osm2po-4.8.8/gb/gb_2po_4pgr.sql"
