Amateur mapper, mostly interested in improving hiking trails in and around Harford County, Maryland.

I use a Garmin GPSMAP 65s for laying down my own traces and determining location when making notes. I usually only edit areas that I have physically surveyed multiple times and use Strava Heatmap and USGS 3D Elevation Program to further guide. I generally upload combined GPS traces after I have made several passes of a particular area - can provide individual traces if anyone needs them. For tagging I generally follow guidelines set by the Trails Stewardship Initiative, unless local convention favors otherwise.

I’m still learning so if anyone has any advice or questions regarding my edits or practices please message me! Also if anyone has a mapping project in or around Harford County MD and feels I could contribute let me know!
