Hello (again).

When I do mapping, as I currently have no GPS tracking unit, I use geotagged pictures, aerial imagery and my own memory, but there are always parts under trees that I can only roughly map, as I cannot take a geotagged picture of each single step. When it is the case, and even as a general question: should I

  1. add data, even imprecise, and tag a fixme on it describing the things to be corrected, or
  2. do not tag anything, possibly leaving only a note describing the data to be added.

I would say the first possibility, as imprecise mapping is better than no mapping at all IMHO, but that leads to inconsistent elements as unconnected waterways made of only some isolated nodes, like when these waterways are mapped only on the small part crossing the highway=* the mapper followed, or kilometers-long straight on ways. I assume that part is up to the renderer, but I'm not sure, so I'd like to have a confirmation on that.

Awaiting your answers,

Regards.

I would add data, even imprecise, and tag a fixme on it describing the things to be corrected or as many others do add note=approximate. Also check that you have tried all the different satellite imagery available, use all the gps traces and check the strava data too (all available in JOSM). Then make a personal endeavour to check the area yourself later with gps.

What's the strava data?

http://wiki.openstreetmap.org/wiki/Strava It is listed under the imagery options in JOSM to use as a background layer. It is also available in ID http://labs.strava.com/slide/
