Betreff: Re: [Routing] export osm to use it in pgrouting
osm2pgrouting has problems with large amount of data.
It depends how much memory you have available.
I am using 2 GB of memory. Not enough??
This could be one reason.
Can you make sure that you created a database and loaded all required functions?
You can also create a routing_template like here:
https://github.com/pgRouting/workshop/blob/master/bin/create_templates.sh
I did all what you wrote, but I obtained the same problem.
Now I tried osm4routing: launching:
Postgis output option:
osm4routing -o postgresql://postgres@localhost/routing -n italy_nodes -e
italy_edges -s /opt/tmp/italy.osm
this brings an error after parsing while trying to save in the db
Csv output option:
osm4routing -o csv -n italy_nodes -e italy_edges -s /opt/tmp/italy.osm
this save the nodes in the csv file but while saving the edges I obtain:
Read 33314731 nodes and 2849260 ways
Step 2: saving the nodes
Wrote 1750193 nodes
Step 3: saving the edges
terminate called after throwing an instance of 'std::bad_alloc'
what(): std::bad_alloc
Aborted
it looks like that both of this tools have problems with large data.
