That was also my plan John. The Kings Park data set looks like a
perfect example. I can load that as a layer and compare the existing
OSM data in another layer. It is not that difficult to select a number
of building traces at a time and bring them in. However the Kings Park
data is already showing some inconsistencies. For Example Fraser's
Restaurant, circular building is showing as orthogonal. Many of the
other buildings are also incorrect.
Oh well perhaps it is just another tool that can sometimes be useful.
Good effort anyway

Seems sensible to me, I'd personally be shying away from imports
without more knowledge of how that works. I was thinking about biting
off very small chunks (even suburbs may be too big for this) and
manually going over them, making sure to not overwrite existing
buildings, and checking them individually to make sure they match up
with relevant imagery. Is there a recommended workflow for this?

Just to flag a note of caution here - I'd recommend small scale
evaluations /only/ at this stage; or if you do bigger test
imports; in a sandbox environment.

If there is interest; later we can create a bunch of tasking
manager jobs for importing small chunks at a time; plus write up
the plan(s) as needed

Hi Warren, I've split it out into .osm files for each of the
WA suburbs [1], see attached small example file for King's
Park. Does something like this work? I can drag and drop them
into JOSM, but I'm not 100% sure if they're formatted or
attributed correctly to be most useful.
Cheers
John

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 South West of WA may be enough of a reduction.
Thanks

Hi Warren, I could probably help with this. What would be
a good size for a chunk? What would be a useful format?

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 data at
https://github.com/microsoft/AustraliaBuildingFootprints
<https://github.com/microsoft/AustraliaBuildingFootprints>
is
much too large for me to handle.
Is someone more skillful than me able to break this
data set into bite
sized chunks?
