Hello,
here are some ideas:
solution1: change a single line of code:
src/netwrite/NWWriter_XML.cpp:192. Change from
if (!e-hasDefaultGeometry) {
to
if (true)
this will cause shapes to be written for all edges in .edg.xml output
solution2: write a python script using sumolib (requires the pyproj library)
when you load a network with
net = sumolib.readNet("myFile.net.xml")
you can access all edges and their lanes along with their shapes using
net.getEdges(), edge.getLanes(), lane.getShape()
you can convert all network coordinates back to lon,lat using
net.convertXY2LonLat(x,y)
then just write them in any format you need
regards,
Jakob
