Release Notes

February 2018

  • S-map data update - There is new S-map coverage in the Grey Valley, West Coast and in the foothills of the Four Peaks Range, south Canterbury. The Franklin area has been remapped, replacing the legacy map – part Franklin County, as well as extending coverage west to Waiuku, south to Onewhero/Pukekawa and east onto the Bombay Hills. The extent was defined by the geology of the South Auckland area; in particular the basalt volcanoes. The Four Peaks Range foothills and Franklin area were mapped using new digital soil mapping techniques, whereas the Grey Valley is based on the legacy survey, NZ Soil Survey Report 46, Mew G (1980) Soils, forestry and agriculture of the Grey Valley, South Island, New Zealand.

  • Minor big fixes. Improved place name search facility.

January 2018

  • Updated the version of the Silverstripe CMS used by S-map Online.

September 2017

  • Release of new version of S-map Online (version 2.0). 
  • The application should work on most desktop operating systems e.g. Windows 7 and 10, and with most newer versions of browsers.
  • The application has been designed and implemented to also work on tablets and mobile devices. However, with the huge number of tablets and mobile devices available we could only test the most common ones and we cannot therefore guarantee that you won't encounter problems, particularly with the layout. Please use the Contact Us form to provide us with feedback on any problems you encounter.
  • As well as the new look and feel, all the basemaps have been updated, land parcels have been added as a new context layer (maps provided directly from the LINZ Data Service), these can be used when generating area statistics, and you can now save the locations you selected on the map and queried to use in a later session. To get a full appreciation of the changes, read the First Time Here? help page.

May 2017

  • New mapping has been added in Canterbury (Lake Heron, Upper Selwyn and Rangitata terraces). Minor corrections to soil attributes and soil names have been made throughout NZ. The need for a ‘Level1’ or ‘Level2’ suffix in the sibling name used in OVERSEER has been removed. A new NZ soil classification layer has also been added which colours soils on soil order.

October 2016

  • The website has been completely revised.  It now uses Silverstripe for content management and includes a user registration capability so that we can have a better understanding of who our users are and can better understand and meet their needs.  The underlying mapping services and functions have not been changed. 

September 2016

  • New mapping in the Waikato (Waipa) and in Northern Hawke's Bay (Tutaekuri, Ahuriri, Ngaruroro and Karamu catchments - 'TANK') has been added.

June 2016

  • As a consequence of S-map data now being directly available in the OVERSEER® Nutrient Budget model we have removed the soils data required for OVERSEER from the factsheets. The OVERSEER® Nutrient Budget now just requires you to provide the sibling name shown on the factsheet. When using OVERSEER just
    • ​Select the link to S-map
    • Under S-map sibling data enter: <<sibling name>> e.g. Keepa_2a.1

February 2016

  • New mapping in the Lake Heron area of Canterbury has been added along with a small area in the Gisborne region. Full soil moisture data for input into OVERSEER is now provided for all Canterbury soils.
  • Also for those wanting soils data for the Canterbury Region, if you click on a location in Canterbury for which there is currently no s-map data, the soil information pop up window now provides a link to a new website, the Interim Canterbury Soils website, which has interim soil data. Soil factsheets can be obtained for this interim soil data.

December 2015

  • License changed from Creative Commons Attribution-No Derivative Works 3.0 New Zealand License (BY-ND) to Creative Commons Attribution-NonCommercial-No Derivative Works 3.0 New Zealand License (BY-NC-ND 3.0 NZ).

June 2015

  • New/revised mapping in south Canterbury and in the Hawkes Bay has been added.
  • A few minor corrections have been made to some of the pedo-transfer functions.
  • A new version of the report functionality, 'Statistics', has been implemented. The figures provided in the tables now take account of all siblings in a polygon and not just the dominant one. See 'Getting Started' for information on how to use this feature.
  • Along with Statistics you can get a list of all the siblings within an area, the area in hectres they make up and the percentage proportion of that area.

April 2015

  • The factsheets have been updated to reflect the soil properties users should enter into OVERSEER Nutrient Budgets v6.2.
  • A description of the hydrological pedotransfer functions can be found here.
  • Minor corrections to some of the hydrological pedotransfer functions has resulted in some changed properties for a few soils.

November 2014

  • New areas in the Auckland region have been added.
  • A few minor corrections have been made to some of the pedo-transfer functions.
  • The Overseer page on the factsheets has been altered to provide additional soil properties where they are available. These values enable a more accurate description of the soil in Overseer.

February 2013

  • Minor changes made to the user interface.
  • Moved whole service to a more stable production infrastructure.
  • Minimum scale at which Smap boundaries can be viewed changed from 1:100,000 to 1:250,000.
  • Soil information pop up window now re-sizable.

July 2014

  • New areas that have been added to S-map Online include the lowlands in Otago/Southland, Hanmer Basin, Greymouth-Hokitika, and Cheviot to Kaikoura. There is also new mapping in the Manawatu and around Otaki.
  • The Profile Available Water (PAW) pedo-transfer function has been further improved. This has resulted in revised PAW estimates for all soils, and changes to some risk categories.
  • The Overseer fields on the factsheets have been updated. The s-map reference name now has an additional character e.g. Raka_3.1 is now Raka_3a.1. Various other minor corrections have been made to the data and factsheets.

June 2014

  • Area report visualizations have been disabled.
  • The Help pop-up window now only appears once in a session.
  • It is now possible to make the mapping window full screen. Use the 'Toggle full screen' button in the top menu bar.
  • Made various user interface changes so that S-map Online now gives a better experience for tablet users. (Note: S-map Online can be used on smart phones but there are known usability problems.)

December 2013

  • S-map database updated. S-map coverage has been extended to include new areas in Canterbury, Waikato and the Hawkes Bay. The new mapping in the Hawkes Bay has involved developing some new Digital Soil Mapping (DSM) techniques applied to a new 5 m Digital Elevation Model (from GeoEye stereo imagery). Various minor corrections have also been made to soil polygon labels throughout New Zealand.
  • You can now obtain an indication of the area of each feature (class) in the selected layer using the report feature.  You can obtain reports either for the whole of the map currently being viewed or for an area you define (draw) on the map. More information on this new capability can be found on the 'Getting Started' page.
  • For those land areas for which s-map data is not yet available, the Soil Information feature presents links to Soil Order and Drainage maps in Manaaki Whenua's Soils portal. The source for this data is the pre S-map Fundamental Soil Layers.

July 2013

  • S-map coverage has been extended to include new areas in the Gisborne, Waikato, Canterbury, Auckland and West Coast regions. Some of the Bay of Plenty (Mamaku Plateau) has been updated. Various minor corrections have been made to soil polygon labels throughout New Zealand. Factsheet terms are now linked to the Glossary (which has been extended).
  • A major update has been made to the way that Profile Available Water (PAW) is calculated. This has resulted in significant changes in PAW, particularly increases in PAW estimates for soils formed from pumice and volcanic ash. Some of these changes are so large that they significantly alter estimates of soil water uptake and drainage from these soils. This may affect consents for water that are based on PAW, irrigation demand calculations, nutrient loss modelling, and other risk assessment or environmental impact studies. Further information on this change can be found in the FAQ.
  • Changes have also been made to S-map online so that it now runs properly in Internet Explorer 10.
