Arcs (Edges) with directions

[Daniel Mota]

Hello all, 

My team is starting an application using lat lon as nodes and edges as road connections between them.

Is there a way Networkx can help me with this effort?

Thanks a lot

Networkx is quite flexible in terms of building graphs with arbitrary nodes and edges. So what you are talking about makes sense for networkx. Indeed others have done this too so you might take a look at eg osmnx which uses open street map data combined with networkx analysis.

Hi,

Distances can be a problem as the distance between one degree of latitude is not the same as the distance of one degree of longitude.  I would use a weight for distances that is calculated in meters in a UTM CRS.
