Hello, SUMO uses UTM by default and shifts the coordinates so that the lower left network corner is at 0,0. However, your original network file was created without projection information (projParameter="!"). In this case SUMO only takes the coordinates it was already given and shifts them without doing any projecting. >From their magnitude one can try guess what the original projection for the vissim data was (possibly UTM).
Do you know from which city this network is? regards, Jakob 2018-04-20 9:22 GMT+02:00 Thuresson, Daniel < [email protected]>: > Hi, > > > > I was expecting absolute values in some coordinate system (as stated in > the manual).
