There are three coordinate systems in play here: 1. WGS84 (lon,lat) 2. UTM (large x,y values in m) 3. shifted UTM (typically small x,y values in m)
You can freely convert between all of them and sumo provides functionality for this (https://sumo.dlr.de/docs/Geo-Coordinates.html) There is a fixed relationship between 1 and 2 (the center of each UTM zone is fixed) but you can freely define the shift (3) and thereby place your origin (0,0) wherever you need. If that doesn't answer your question, please try to restate it with a usage example. regards, Jakob Am Di., 7.
