Hello, sumo uses cartesian (flattended) geometry with meter position values. When building a network from lon/lat data you need to set the netconvert option --proj.utm to affect proper conversion. If you need to convert back from simulation coordinates to lon/lat you can use either TraCI or sumolib to do so http://sumo.dlr.de/wiki/TraCI http://sumo.dlr.de/wiki/Tools/Sumolib function *net.convertXY2LonLat*()
