[pgrouting-users] osm2pgrouting oneway misreading

[Tao Romera Martinez]

Hi Sylvain,

I think I was not able to import data using osm2pgrouting, so I
instead used osm2po.
Here is the memo I made for myself on how to use it:

IMPORTING DATA FROM OSM INTO THE DATABASE

1. Download osm2po from http://osm2po.de/download.php?lnk=osm2po-4.4.4a.zip
2. Install in for example /usr/share/osm2po:
sudo unzip /home/tao/Downloads/osm2po-4.4.4a.zip

3. Download osm file
4. Copy file to your osm2po folder:
sudo cp /home/tao/Downloads/map.osm ./

4. Convert OSM file to DB file:
sudo java -jar osm2po-core-4.4.4a-signed.jar prefix=at <file>.osm

5. Import DB file into database (username = postgres):
psql -U postgres -d <your_DB> -q -f "/usr/share/osm2po/at/at_2po_4pgr.sql"

Good luck,

Tao
