New Zealand Mapping Project, the home of New Zealand on the OpenStreetMap wiki. |
| Hello! Welcome to the project for mapping efforts in New Zealand! You can find here national events, ongoing projects, map status and mapping guidelines, as well as links to other pages directly related to the mapping of New Zealand. You may also find a list of contacts and mappers involved with the OpenStreetMap community in New Zealand. |
Welcome to the New Zealand mapping project page - this page is dedicated to helping OSM mappers working on adding content in New Zealand.
 | Please don't retrace LINZ coastlines or other source=gps items with Bing satellite traces which for many parts of the country are very badly aligned (60-100m out) and of inferior quality to the aerial ortho-photographs the LINZ data was traced from. |
If you notice a problem on the map and don't have time to fix it or are not sure what needs to be done, then please leave a note in the relevant sub-section, so that other people can help resolve it.
Alternatively, Notes is a great way of simply leaving notes on a map, without having to get into editing, or registering.

OSM Auckland meetings
Meetings currently suspended. Would you like to start meetings in Auckland?
See OSM Auckland for more info.
OSM Wellington meetings
I'm organising a Wellington OSM meet up. All are welcome to attend
See OSM Wellington for more info.

Guidelines
Christchurch City Council Traffic Signals
On 2013-12-07 at OpenHackChristchurch, a number of volunteers tagged new and existing traffic lights in Christchurch based on official Christchurch City Council Traffic Signal Plans. The tags added to highway=traffic_signals include:
- chchsid - the number linking to the CCC Traffic Signal Plan
- source - URL link to the pdf of the Traffic Signal Plan
The Traffic Signal Plans refer to an intersection as whole, if there are two or more highway=traffic_signals, then all the traffic signal nodes are tagged with both the chchsid and source.
Department of Conservation
Huts are tagged with a reference to the DOC asset ID using ref:doc=*. See the DOC page for further information.
Suggestions
Some tags we may need to create, for satisfactory mapping of New Zealand
- Need to agree how to match the classification of the New Zealand road network onto the Key:highway tag. For example should State highways be 'trunk' or 'primary'. Idealy the end result could be included in Key:highway#International_equivalence table. A list of State Highways can be found on here[4].
- Talk:Proposed_features/mtb:scale#New_Zealand_grading_system - How should we tag mountainbike tracks with grades?
- Proposed features/Volcano
- other geothermal activity
- fumaroles
- steam vents
- bubbling thermal mud pools
- see: Craters of the Moon
- Braided rivers, [5], Need to create a proposal for these based on Proposed_features/Large_rivers --rcr
- Alternate Maori place names, tag with name:mi=Māori name. Always add
name:enas well, even when it's the same asname. (e.g. name=New Zealand name:en=New Zealand name:mi=Aotearoa). See Key:name for more detail. --rcr - Proposed_features/Power_plants - hydro/geothermal power
- Proposed_features/Railway_yard - numerous sidings around Auckland and elsewhere
- We need appropriate tags for our DOC (and other) backcountry huts as the current tags really only apply to the European style mountain huts which are really more like wilderness chalets; nearly all are private and/or operate like paid hotels, see: Proposed_features/wilderness_mountain_buildings and Talk:Proposed_features/wilderness_mountain_buildings --gerkin
- -- see discussion about this in the comments section of the bivouac_pnt layer in Rob's LINZ-2-OSM web app. --Hamish Dec 2010
new_zealand.osm
as NZ territory is across the international date line, data for the entire country needs to be downloaded in two pieces:
North and South Islands
on any system with wget installed (most GNU/Linux and BSD systems have wget by default, it can be installed on windows), this code will download an excerpt of the planet.osm file, containing data for new zealand's north and south islands
wget -O new_zealand.osm \ http://www.informationfreeway.org/api/0.6/*[bbox=165.9,-47.9,179.0,-34.0]
alternatively, use this as the download link:
- http://www.informationfreeway.org/api/0.6/*[bbox=165.9,-47.9,179.0,-34.0]
- There is a weekly extract for New Zealand hosted on Cloudmade, currently (2010-05) the compressed version is 28.2MB.
Chatham Islands
- Populated by the LINZ data bulk import
wget -O chathams.osm \ http://www.informationfreeway.org/api/0.6/*[bbox=-177.4,-44.5,-175.7,-43.5]
Other areas
See the LINZ#Areas wiki section for more.
Place names
- Here is a page for discussion of New Zealand/Place names, including Māori localization and what to call populated places of varying sizes.
Issues with alignment of Bing imagery
a number of OSM users are reporting poor accuracy of the Bing images - alignment is out by up to 20m in some areas of the world (e.g. Milford Sound out by approx 60m). The intention of the table below is to collect information regarding the accuracy of the images in New Zealand. It may be useful to carry out the same checks at different zoom levels
See also: True_Offset_Process and Talk:Bing for further discussions regarding accuracy of Bing imagery. Where available, large numbers of GPS traces can be used to correctly align the imagery, for example in JOSM using the Imagery plugin (see http://josm.openstreetmap.de/wiki/Plugins), however this offset may only be valid for a few hundred metres, at which point the alignment may drift by > 5m, and re-alignment using GPS traces will be necessary.
The alignment issue is inherent in aerial or satellite photography. Due to the different terrain heights as they present themselves to the camera lens and the curve of the earth this produces a 2D image that is not possible to get exactly aligned on all four sides. When the image has to be aligned to other images that are stitched together to make up the full background canvas it is quite commonly the case that they do not line up completely. As cameras get higher resolution and can take in more terrain in one photo this problem gets reduced but never eliminated. See http://en.wikipedia.org/wiki/Orthophoto for more information about how this is corrected. Unless imagery is orthorectified, these problems always occur. Enzedrail 21:45, 2 January 2012 (UTC)
