Where are you all finding this info? I've had a look at RapiD & they either don't have much on the GC, or I'm just doing something wrong (which is quite, quite possible! :-)), because I can't see anything to check? Thanks Graeme ___ Talk-au mailing

Looks like my other message didn't go through. Agree re the slight rotational issues; and it being at about the level of a new-intermediate contributor from the samples around Adelaide I managed to look at. I found sometimes, it would mistake bright concrete as part of a building footprint.

Hi John I use  JOSM.  Any file format that I can bring in as a layer would be fine.   I can then select, copy and paste the tracings into an active layer for upload, checking as I go.  Certainly faster than tracing by hand. I am not sure when JOSM get chocked by file size, but say Perth or the

Also buildings which are touching like a shop fronts are just one polygon, but I don't think you'd ever be able to do this too reliably without a survey anyway. Even if there is a small gap between buildings eg a garage and residence sometimes it will join them into a single polygon. What I feel

Hi Warren, I could probably help with this. What would be a good size for a chunk? What would be a useful format? On Wed, 21 Oct 2020 at 07:21, Warren wrote: > Hi > > I am in the eastern suburbs of Perth where minimal buildings have been > traced. I would be happy to check trace data in my

Hi I am in the eastern suburbs of Perth where minimal buildings have been traced.  I would be happy to check trace data in my area, lets face it hand tracing is not much fun  and very time consuming.  I think some inaccuracies are acceptable, they can be modified as they become apparent. The

Just as a comment: there is nothing so time consuming as fixing badly mapped buildings (essentially drawing them from scratch is nearly always faster), I would only import building outlines that are at a quality level that you would not want to change them except if the building itself has

Hi folks, I was wondering how mapbox had coverage of areas that hadn't been traced into OSM; and after a bit of digging came across this ODBL data: https://github.com/microsoft/AustraliaBuildingFootprints As fun as hand tracing data is; I'd be pretty keen to swap to small scale imports of this,
