Re: [OSM-talk] Changeset Governance [was: Announcing Daylight Map Distribution]
I agree with Greg that there are lots of shades. E.g. places I have been to but not recently (may have changed). I try to describe these facets in the changeset comments with phrases like "no specific local knowledge" (means I do know the area, but not the place I have edited, as opposed to "no local knowledge"=no clue). Or "no recent local knowledge" (I know the place from the past but have not been there recently).

I always put survey+imagery in the last 3 cases.

I'm very sympathetic to knowing the on-ground-ness of a change. But I think it's shades of gray. This list illustrates what I mean: * armchair a place I have never been to, and which is so far away that I am not familiar with the customs. An example would be me (US) editing in Africa. * country-armchair as above, but I know the country norms. Me editing in Glacier National Park. * local-armchair as above, but I know the region norms. If I edited some town in MA that I haven't visited (perhaps because I was going to visit), but I generally know how things are. * visited but mapping done by imagery Here, I am editing a place where I've been at some point reasonably recently and have some clue, but my edits are based on imagery. However, my recollection is good enough to avoid most of the armchair issues. An example is me fixing up crosswalks and sidewalks two towns away, but not from field mapping notes. I don't consider this armchair, but it's iffy. * editing soon after a visit I got someplace, maybe make notes, maybe remember, and edit based on some combination of imagery, gpx tracks, notes and memory. I think this is squarely not armchair. * editing while there Actually using an editor while being in the place being edited. I would basically split this into three armchair and three not armchair. So basically I think source including imagery does not really imply "armchairing", in that the use of imagery is not the point, but a lack of familiarity with what's on the ground. I almost always load and look at imagery when editing after being in the field. I line up ways from imagery when that works, becuase I have come to believe from experience (with specific imagery sources) that this is more accurate than my gps tracks. (I have been experimenting with raw GPS data and post-processed PPP solutions, and those I think are close to good imagery.) ___ talk mailing list talk@openstreetmap.org https://lists.openstreetmap.org/listinfo/talk
Re: [OSM-talk] Changeset Governance [was: Announcing Daylight Map Distribution]
Hello again, very big sorry for the delay, was bussy :) I updated the page https://wiki.openstreetmap.org/wiki/Changeset/Governance to include your points of corrections. I also generalized it to comply with writing standards of the OpenStreetMap Wiki Community. Sry to have created the page in the namespace of "Changeset". But I made it clear that it is a stub and not official. My aim is inspiration rather than dictation.

Changesets made during armchair mapping need to include the hashtag "#armchair" and the source the mapper used in the `source` changeset tag. > happened to the good old source tag where source=survey would point to mappers on the ground in my recent commit I changed the idea to include `source=survey` for changesets made during surveys.
