Hi Duccio Aiazzi,

I don't have an answer to your specific question, but I just want to call your attention to the OSMnnx , which makes it incredibly simple to create a road network from OpenStreetMaps data with a single line of code. https://github.com/gboeing/osmnx

OSMnnx also allows one to save the graph as a GraphML file, which I believe can be easily read by graph-tool as a planar graph if I'm not mistaken.

best,

I'm interested in calculating some centrality measures on a road network of a city. The geometry of the road network, from Open Street Map, is stored in a postgreSQL / postGIS database and can also be exported as a shapefile or a geojson. What is the best way to import the geometry in graph-tool as a planar graph?
Thank you,
Duccio
