Hello, netconvert automatically shifts the coordinates to the origin. The warning indicates the the coordinates are still larger even after shifting which either indicates that your network input contains at least one very strange coordinate or that the something with the geo-projection went wrong. Possible the commands --proj.utm and --shapefile.guess projection interact badly. You can check for the projection that netconvert used by looking in the <location> element at the top of the generated .net.xml file. regards, Jakob
