Welcome to the Mapping section of the Orienteering NZ website.  These pages provide information and resources on how to prepare orienteering maps, and you can also chat with others about Mapping through the Chat area.

This page is intended as a central location where New Zealand based mappers can obtain all the necessary information for their mapping work. For any help or advice not covered here, please contact the mapping committee.

Resources

Below are links to specifications and guidance for orienteering mapping. It is important that these are followed as they provide a method of standardizing maps across New Zealand and internationally. The list was updated Jan 2020.

Foot Orienteering

  • International Specifications for Foot Orienteering Maps
    The IOF Mapping website, which contains links to the specifications for standard foot orienteering maps at 1:15,000 (ISOM2017) and sprint orienteering maps at 1:4000 (ISSprOM2019) These scales may be proportionately enlarged in many situations, such as for older age classes.
  • Printing Test Sheets.
    Every type of printer treats the map file in a slightly different way. For top-level events the IOF urges us to select the printer and adjust the CMYK values so that the result matches that from a very high quality printer. Get the test map file from the IOF website (above). Get a test print from the ONZ Event Liaison Officer.
  • 2019 Changes to our Sprint Orienteering Maps.
    Non-technical advice prepared Sep 2019 for NZ clubs about these changes, which apply from Jan 2020. There are few changes which will be noticed by participants.
  • 2019 Changes to our Sprint Orienteering maps.
    Advice prepared Sep 2019 for NZ mappers on adopting ISSprOM2019, and converting previous maps to comply.
  • OCAD 11 file for the new Sprint Spec ISSprOM2019. (Note: Right click link and select “Save as…”)
    This comes into effect in 2020. Straight from OCAD, a few symbol features may have been lost on saving back. It contains a legend suitable for printing at 1:2000 for fieldwork, or you can use it as a source of symbols for OCAD or OOM. It includes CMYK changes according to Appendix 1 of ISOM – be wary. This re-created file picks up corrections up to June 2020. Here’s a PDF of the legend.
  • Cross Reference Table to convert from a recent ISSOM2007 file to the ISSprOM one. (Note: Right click link and select “Save as…”)
    We call this a “vanilla” CRT as it doesn’t contain extra user-added symbols, but the COMMENTS in it make it much easier to edit. You might choose this method if (a) you have lots of files to convert or (b) you dont have OCAD 12 or 2019 which have an easier convert function. It is provided here as a TXT file. Before using it with OCAD you’ll have to change the extension to CRT.)
  • Collected Hints, Difficulties and Issues with ISSprOM Symbol Conversions.
    Please add contributions by writing to the Mapping Committee.
  • 2017 Changes to our Standard Orienteering Maps.
    Non-technical advice prepared in June 2017 for NZ participants about these changes, which applied from Jan 2018.
  • 2017 Changes to our Standard Orienteering Maps.
    Advice for NZ mappers prepared in June 2017 on adopting ISOM2017, and converting previous maps to comply.
  • OCAD 11 file for ISOM2017-3. (Note: Right click link and select “Save as…”).
    ISOM continues to change; this file has changes as downloaded from OCAD 21 Dec 2020. A few symbol features may have been lost in saving back to version 11. It contains a legend suitable for printing at 1:7500 for fieldwork, or you can use it as a source of symbols for OCAD or OOM. It includes CMYK changes according to Appendix 1 of the spec – be wary. Here’s a PDF of the legend.
  • ONZ Vanilla CRT (TXT 10KB) (Note: Right click link and select “Save as…”)
    Cross Reference Table to go from the OCAD-provided ISOM2000 symbols, to an ISOM2017 set. OCAD provides one of these, but this one has extensive comments to assist editing, which you will undoubtedly have to do. (Note: some computers think files with an extension of CRT are security certificates. It is provided here as a TXT file. Before using it with OCAD you’ll have to change the extension to CRT.) Refer to Advice to Mappers for Changes to our Maps for information on the CRT file use.
  • New Zealand Specific Symbols (Appendix 8, page 20)
    New Zealand uses for special IOF symbols on NZ maps. This refers to the ONZ Competition Rules, but Appendix 8 there is out of date. In the meantime refer to “2017 Changes to our  Standard Orienteering Maps“, as above.

Data

Below are links to important locations for sourcing basemap material, including contours and aerial imagery. Other council websites not listed below may have aerial imagery or other data, often located under “Property Information System” or a similar title.

  • Land Information New Zealand Data Service
    Free online access to New Zealand’s most up-to-date land data. Look especially at Aerial photos and Elevation (contours and DEMs).
  • Koordinates
    Online access to a wide range of data sets across New Zealand. Some data in Koordinates is commercial and requires payment before it can be downloaded.
  • Open Topography Free online access to high-resolution topography. Hosted by the University of California, San Diego but holds raw Lidar (point cloud) data for New Zealand. Whereas LINZ holds elevations processed into contours and DEMs on a regular grid, this site holds all recorded Lidar returns.
  • WAMS (Walking Access Mapping System)
    WAMS is an online system using GIS technology to provide a view of the legal boundaries of public land. This boundary information (known as the cadastre) can be viewed against topographical maps or aerial photographs of the entire country. Important for locating areas where orienteering may be more easily permitted.
  • Magnetic Field Declination Around New Zealand
    Provides information on the declination of magnetic north from grid north and true north across New Zealand.
  • Canterbury Maps
    Online access to a wide range of data sets across the Canterbury region
  • Auckland Council GIS
    Online access to a wide range of data sets across the Auckland region

ONZ Mapping Community Wiki

This contains conversations about mapping on the forum at www.maptalk.co.nz, up to Apr 2016. It was the wrong tool for managing informal discussion and has not been updated since. However (apart from lack of currency) it does contain useful information organised into topics

ONZ Mapping Community Wiki

There is current mapping discussion on a Facebook Group called “Orienteering Mappers New Zealand”. There is also “Orienteering Mappers Australia”, and a more active “Orienteering Mappers Int.”
