[GRASS-dev] ​Can GRASS compute the line graph representation of an input graph?

[Blumentrath, Stefan]

Hi Anita,

For more sophisticated network analysis I tend to use igraph:
http://igraph.org/
It is quite easy to understand, well documented, efficient and supports also calculation of line graphs. It comes with both Python and R APIs.
Usually I feed graphs into it from GRASS (v.net) or PostGIS. I have not tried the new GDAL/OGR network driver...

Cheers
Stefan

I don't think so, but it seems really interesting
