Walking, hiking and mapping with a Garmin GPSmap 66i, set to GPS+Galileo and WAAS/EGNOS. Under good conditions that should give about 1-2 meter precision, but there are exceptions so I also check with background maps. I mostly see to that hiking paths are properly in place and with the proper features, including the minor paths you may otherwise only see on an orienteering map. I may also add features like streams. So there is much to do…
