Hello Peter,

This comment attracted my attention. In my experience it is quite
usual that when local issues are discussed in local forums, it is done
in the local language, whether English, French or Swedish. I have not
often seen a summary written in a foreign language towards the end of
the discussion. Perhaps it is common in the German-speaking forums or
mailing lists?

Limitations of API should be dealt with for the convenience of the
people doing the mapping, not of the API. OSM tooling for viewing
changesets and area history is known to be poor but this cannot be a
determining factor for contributing to OSM (otherwise I request that
rosemary 0.4.4 or wheelmap changesets with bounding boxes spanning the
globe be blocked immediately). Would you rather have contributors
figuring out how to deal with API limitations and making pretty
changesets, or doing mapping or indeed importing?

This cannot be surprising in an area where forests are largely unmapped.

It might be charitable to note here that there is a large discussion
about what is supposed to be the meaning of landuse=forest, and of
landuse and landcover tags in general, with no OSM-wide consensus that
I've seen so far. If there were trees grown in an area, they were cut
down for wood, and it's regrowing as scrub, is the land still "being
used as a forest"? Is wetland=swamp automatically not a forest?

Indeed from imagery it looks like the lake, which was previously
mapped (seemingly by hand in changeset 29491171), is inaccurate, and
the bits of forest that are now mapped at 16/59.0365/16.0570 appear
fairly accurate to me comparing to local orthophoto (Lantmäteriet
Historic Orthophoto 1975). From the achavi visualizations we can see
that the lake outline was largely unchanged. Would you have liked to
see the lakes manually fixed while importing forests?

And who might issue such a permission? The local community? The
already overworked DWG? OSMF?

Best,
Jarek
