I'm interested in this as well. I've imported about a dozen parcel boundaries near me to experiment with, and it is difficult to work with. In an ideal world fences would always line up with boundaries, or there would be clear changes in land cover, however this is rarely the case. As much as I love to add tons of detail to OSM, I'm having trouble justifying adding parcel boundaries.
I do think we should add a wiki article on this though, if nothing else than to collect links to the various ML discussions on the subject. -Josh On Mon, Mar 21, 2011 at 3:06 PM, Ian Dees <ian.d...@gmail.com> wrote: > Hi Marten, > I'd be happy to have a discussion somewhere public (as my opinion is one of > many) like IRC or on this mailing list. > To clarify what I meant about parcel data: I'm assuming you mean parcels in > terms of household property boundaries.
