This page is a bit of a sandbox where we will hash out how we will match features for the LINZ data import. The full list is stored in the LINZ-2-OSM web app with JavaScript logic. When complete we will publish the data_dtd.xml file here.

• See the LINZ OSM wiki page for more info about the import.

• See the LINZ data sets page for a list of LINZ datasets. The LINZ online data dictionary which explains each layer in detail can be found here.

Further discussion needed

Many of these will eventually need to have a Proposal submitted. For now we just do our best.

• natural=tundra [landuse= is for areas changed by man (such as a managed forest, a residential area), natural= for unchanged areas] [only in AKL Isl/Antarctica datasets?]
• {landuse|man_made|farm} = {stockyard|corral|pen} animal enclosure
• waterway= {soakhole|sinkhole|karst|dolite} ?

This is the end node of a stream where it disappears into a hole/cave, as you might find in limestone country. Presumably it pops back out somewhere else as a spring. Possible aka's: "soakhole", "sinkhole", "dolite", or "karst". Sinkholes (with or without water flowing into them) can be quite big, so can be both areas and nodes.

Why not use natural=cave_entrance? In combination with waterway=stream(e.G.) and tunnel=yes the objects could be described pretty exact imo. No need to invent too specific tags. -- Malenki 12:05, 25 April 2010 (UTC)

PS: I imply you mean it's the end of the waterway on layer=0, continuing on layer=-1, not really the end of the waterway at all.

this looks good myfanwy 01:32, 23 April 2010 (UTC)

I found a sinkhole (de:Schluckloch) last week in Germany (Sauerland) and while tagging it, I was confused: there are more than 4000 "soakhole" in the OSM database, 99% from the LINZ import. After researching the word "soakhole" for a while I found, that this word is in New Zealand often used for stormwater reservoirs (de:Regenwasserbehälter). After looking closer at the LINZ data it seems that they tagged the end of a stream with this tag where the stream disappears into the underground. I then tried to find the word "soakhole" in Google translator and leo.org, but none of them provided a German translation. Also the OSM wiki has no reference to "soakhole" except in conjunction with the LINZ import. Looking at the pictures provided by Google after searching for "soakhole" indicates, that a "soakhole" is a container for stormwater. Wikipedia does not provide any information regarding "soakhole", instead redirects to sinkhole.

On the other side there is quite some information around for the key "sinkhole" which indicates, that this key perfectly fits to the situation that a stream is disappearing in the underground. The OSM database contains approx. 500 "natural=sinkhole", some of them representing the end of a stream, some of them representing just a convex earth surface that exists may be because the cave below broke down or something similar.

I suggest, that the LINZ import "soakhole" tags should be renamed to "sinkhole". In addition I suggest, that a sinkhole that represents the end of a stream should be tagged as "waterway=sinkhole" whereas a sinkhole which has nothing to do with a stream should be tagged as "natural=sinkhole".--Markus59 (talk) 15:15, 29 December 2013 (UTC)

• For the things where Proposed features/Mining is suggested I'd like to mention that the proposal is rejected regarding the page. Why not use man_made=works which most of the LINZ name implies already (gravel works, ironsand works, lime works...) -- Malenki 12:28, 25 April 2010 (UTC)

-- Mining may have been rejected, but there has been (IMO) been no appropriate/better replacement proposed or accepted since and it should be resubmitted with the same tag name but a better defined description. As for man_made=works, this is way too broad and like the mining tag(s) needs much refinement yet. (no pun intended) Happy to use "works" where appropriate though. --Hamish 09:15, 27 April 2010 (UTC)

building_pnt

Points representing buildings. The tricky bit is matching the building_use attribute to favoured OSM amenity/man_made/tourism/etc.=* value.

• building_pnt entry in LINZ's data dictionary

• There is another similar layer called "building_poly" which this list will be reused for. Not necessarily - this would depend on the type. for example supermarket would become:
• the building outline drawn as a poly, and tagged with
  • building=yes
• a point at the rough centre of the building, tagged with
  • shop=supermarket
  • name=Foodtown Beach Road
  • operator=Foodtown

Are you sure? Why would we have a separate point when the whole building is used for that purpose? ammenity=, shop=, etc can be used on an area.

• • yes, i'm sure. a building and the shop in it are two separate items. there's a building in akl called 'Queen's Arcade', which contains a music shop called 'Marbeck's'. if we create a closed way, how do we tag it:
• building=yes
• amenity=music_shop
• name=Marbeck's, or name=Queen's Arcade?

which is the name applying to, the building or the shop?

the building isn't called Marbeck's and the shop isn't called queen's Arcade, so tagging it in this way is wrong - the two need to be separate. there's nothing to stop the shop being a way rather than a point, but it needs to be a different way

• it is assumed that these will all get building=yes
  • not all - some will have their own building=* tags already created, and some i think we should create
  • to clarify: generally, the 'building=' tag defines the form of *building itself*, the 'man_made/amenity/toursim/etc.=' tag defines what is done *in the building*. osm is not perfect or particularly consistent, so there will be exceptions to this

building_use attribute

• The Finalised column is for the "LINZ Team" to check off what we have finalised as a first pass. We will debate these once we have them all cleared, and then sign-off on them before creating out mappings.
• "LINZ Team" voting. If in conflict pls comma sep like "-,+".
  • -- veto
  • - not happy with it
  • + fine with me
  • * seconded (by someone else :)

If you change a tag's key or value, please remove any prior voting results for the tag as they will no longer be relevant.

fish hatchery	amenity	fish_hatchery	0/0	+	+ product=fish; not to confuse with a fish farm, fish factory, or aquaculture site
forest headquarters	amenity	forest_office	21/0	+*	A german user I know uses to use amenity=forest_office, I tend to use this too. A Proposal would be handy. ;) See also translation at LEO.

golf driving range	leisure golf sport	golf_course driving_range golf	1/0	+,-,-	leisure=golf_course Note that we already have golf_crs_poly areas tagged as leisure=golf_course. Any way to distinguish the two? in progress: Proposed_features/Golf_course (either we adopt these straight off, or complete them) leisure=golf_course+amenity=driving_range: Proposed_features/Golf_course#Amenities Golf driving ranges are either inside an existing golf course (http://www.tgolf.co.nz/company/driving_range/dr.php) or stand alone driving range (http://bit.ly/bD2uyJ). I think we should always tag amenity=driving_range for these. - Glen how about with leisure=golf_course for _poly, and without for _pnt? drop l=golf_course, add sport=golf? HB: I'd like to drop leisure=golf_course.RP: i'm happy with sport=golf, but not amenity=. owuld suggest using golf=driving range
greenhouse	building	glasshouse	358/0	+,+	aka glasshouse. see Proposed_features/building and "nursery" below, and Tagwatch/Descriptions/en. landuse=greenhouse_horticulture seems for larger industrial sized installations.

hall	amenity	public_hall	799/0	+*	amenity=public_hall [needs proposal] I don't think historic is really appropriate, these are more social town halls in small villages.

livestock	building landuse	barn farmyard	0/0	+	farm=? Added landuse=farmyard -- Glen
lodge	tourism	chalet	157/1	+*	tourism=chalet if strictly private or tourism=alpine_hut if open to public. Avoid overlap with huts. It would be needed to know what is understood by lodge. A lodge like the lodges in "club skifields" is definitely no chalet but an alpine_hut as they are run privately but open to everyone (though club members enjoy discounts, just like members of alpine clubs do in alpine_huts) In the NZ sense I expect 'lodge' is meant to be a strictly private remote uberhut, usually as a base for hunting/fishing trips. e.g. Kisbee Lodge in Dusky Sound, and not anything to do with a ski lodge.
marae	amenity	marae	530/2	+*	amenity=marae. amenity=place_of_worship + religion=Maori?? No, a Marae is more generally a fenced in town hall grounds containing a meeting house.
meteorological station	man_made measurement	measurement_station weather	0/1	+*	Proposed_features/Observatory: man_made=observatory+observatory:type=meteorological ?, see also Is:Map_Features#Weather_survey_stations Proposed features/measurement station + measurement=weather

mill	man_made	mill	555/0	+*	it depends what the mill does. is it for grinding crops? or generating electricity? perhaps historic=yes?
monastery	amenity access	place_of_worship monks	5/0	-	building=monastery? see also historic=monastery. religion=??? - This is New Zealand so I don't think we have historic monasteries in the same way as Europe. -- Glen RP: the access bit is not appropriate here - it's talking about a legal distinction. place of worship looks good. -- The monasteries are historic for New Zealand. The Wellington Monastery is over 100 years old now. Whilst not the same as (for example) the Monastery at Monte Cassino, it is still historic. HB: just because one of them is historic doesn't mean they all are.
museum	tourism	museum	1/0	+*	tourism=museum
natural gas plant	man_made product	works natural_gas	35/0	+*	Proposed features/Mining, resource=natural_gas. (it's not a mine it's a processing plant)
nursery	building	plant_nursey	0/0	+*	Proposed_features/Plant_nursery is landuse= appropriate for a building? it depends - landuse is endlessly abused, and used for all sorts where mappers won't put in effort to create useful tags.
observatory	man_made	observatory	5/0	+*	Proposed_features/Observatory; landuse=observatory for building polygon, man_made= or building= for building point version?
outdoor pursuits centre	tourism sport	sport outdoor	0/0	-	+ sport=outdoor ?

ski club	leisure	ski_resort	0/0	+	see Ski, see also Sport. In new Zealand a ski club commonly refers to community run skifields on the Souther Island, like Broken River, Craigieburn or Temple Basin. If there is only a POI there is no reason for import. Al skiclubs in Nz are already in OSM (but often missing the rope-tows ....). :: IMO import then rm dupes-assume nothing! "All" ski clubs bulk import documented? They are not all there - This is for the ski club building remember so leisure=ski_club works. The rest of the field can be tagged as per the Ski tags.

surf club	emergency_service sport	water surf_lifesaving	24/0	+*	as in volunteer surf lifesaving station? emergency=yes? I guess Sport can be helpful here. (this has nothing to do with the sport of surfing) amenity=surf_club? see Proposed_features/Emergency_service Surf Lifesaving is a sport on its own right.
