Welcome to the wiki project New Zealand page - this page is dedicated to helping OSM mappers working on adding content in New Zealand.

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.

Tag Suggestions

Some tags we may need to create, for satisfactory mapping of New Zealand

Christchurch City Council Traffic Signal Plans Tags

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.

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]

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)
