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, Rafael H M Pereira urbandemographics.blogspot.com On Sat, Dec 2, 2017 at 7:28 AM, Duccio Aiazzi <[email protected]> wrote: > I'm interested in calculating some centrality measures on a road network > of a city.
