Hi, we already had german VISSIM networks here which used Gauss-Krueger projection for the so-called DHDN (Deutsches Hauptdreiecksnetz). If the network originates from local municipalities there is a good chance that it uses the local standard like https://sv.wikipedia.org/wiki/SWEREF_99 or https://sv.wikipedia.org/wiki/RT_90
