linz2osm: merge ac_buildings
Closed over 6 years ago by StephenDavis
Hello StephenDavis, as you probably know all data imports to OSM are subject to our import guidelines (http://wiki.openstreetmap.org/wiki/Import/Guidelines) which include, among other things, that a public discussion is required before the import. I cannot immediately see the discussion of your LINZ import. Please explain.
The source tag ideally should point to the discussion.
And tags like LINZ:dataset=mainland are not tags useful to OSM mappers or consumers. Discussion about tags like that would be the result of creating an import plan in advance, and showing it around.
Hi, woodpeck and Bryce: this is part of the very long-running LINZ import, which you can see on http://wiki.openstreetmap.org/wiki/LINZ, tracked on linz2osm.openstreetmap.org.nz. See also the discussion on the nzopengis mailing list https://groups.google.com/forum/#!forum/nzopengis which is the NZ equivalent of OSM country-specific talk lists.
These tags are there to allow us to automatically update these features when the source data changes, or we change the tagging formula. The format was discussed when we began the LINZ import.
These tags are not intended to be maintained in OSM. Once other mappers start to touch the data, it's fine if the tags go missing: if other people want to update the data by hand that's much better than an semi-automatic update (they are still verified by hand) done through LINZ2OSM.
Could that be collapsed down to a single key?
The current one does not have a primary key or object reference to the LINZ dataset.
Make that "ref:LINZ"
> Could that be collapsed down to a single key?
In principle, sure.
It was kept as separate tags to make it easier to query. If you feel strongly about changing the existing scheme, though, I suggest you start a discussion on nzopengis, rather than commenting on a changeset.
Bear in mind that we did a lot of discussion during the original proposal about how to tag. Robin Paulson was heavily involved in that.
My comments are independent of Robin Paulson's. I'm a database person, and have done OSM imports (including controversial ones). I'm not an enemy of imports, but an advocate for good ones.
Fair enough. There's a lot of background to this, is what I'm saying. This is not a new import, in fact it's been in progress for several years. If you've got things to say about the LINZ import in general, it'd be best to take them to nzopengis and/or the imports list.
This is not part of the LINZ import, it is completely separate and significantly different. LINZ is a central government department which handles land packets, this appears to be (correct me if I'm wrong), building outlines, from Auckland Council.
Hi Robin, as we discussed on nzopengis, these data sets from AC and WCC are available under the same terms, and provide a more comprehensive set of the same data. If you want to discuss it further, please do so on osm-import or nzopengis, rather than a random changeset.
On another note, I'm between jobs at the moment, and don't have a huge amount of time for OSM at present. I'm not continuing with any LINZ2OSM merges for the time being, I'll let you know when I start again if you want.
I also think it might be a good idea for a meetup sometime: other than Glen, I haven't seen much of the NZ OSM community in ages. It might also be about time to discuss LINZ2OSM and where it's going.
