Hello, generally speaking, only netconvert will support generation of .net.xml files (it is tricky). The most sumolib might do in the future is generate plain-xml input files from a loaded and modfied network as input for netconvert. However, your use cases are already supported.
1) In the latest development version (20a9fc9e78f24f2555cf3e3ed00ac7f0d983736d) you can merge geo-referenced networks simply by loading them together with netconvert: netconvert -s net1.net.xml,net2.net.xml -o merged.net.xml If you do not want to build this version from the github sources, wait until tomorrow to download the updated binaries here: http://sumo.dlr.de/wiki/Downloads#SUMO_-_Latest_Development_Version 2) You can patch an existing network with z-data from various sources: http://sumo.dlr.de/wiki/Networks/Elevation regards, Jakob 2018-05-15 12:38 GMT+02:00 <s...@mm.st>: > Hello, > > I have two networks that were originally converted from OSM to .net.xml > and heavily edited in `netedit` afterwards.
