Via Representation of network flows / http://gis.stackexchange.com/questions/778/representation-of-network-flows I found JFlowMap. It uses the approach I described: https://code.google.com/p/jflowmap/wiki/HowToPrepareData I just don't know if it can also export to shape... [question off-list:] > do you mean something that just draw the lines or that will create/manage actual line features? A line drawing tool which would allow to maintain connections of lines if nodes are shifted. The background for all is that the simlation and design tools for networks can export lines (e.g. power lines, telecom lines) or nodes as lists but no logical structure. A typical schema: http://en.wikipedia.org/wiki/File:Electricity_Grid_Schematic_English.svg http://en.wikipedia.org/wiki/File:One-line_diagram.svg So I wonder how others are transferring such information into the GIS/geo domain.
