Re: [sumo-user] Vehicle position output 
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

Best regards,
Michael
