It's probably not appropriate for adding that data in OpenStreetMap. <div><br></div><div>You can tag a way as barrier=wall.</div><div>You could add the tag source=gps, but that tag shouldn't be used too much and is better for adding the tag to the changeset.</div>

<br>
Been it this for a few months now, got a Garmin Etrex Hcx, quite pleased with it's accuracy but am wondering how best to add my personal survey points to OSM. When I come across a land feature or man-made feature that is visible from sat imagery that is very distinct, such as the corner of a wall, I like to take an averaged waymark, with as many points as I have time for, I can usually get the approx accuract down to less than a metre. How should I tag such waymarks on OSM?<br>
