A LINZ Data Service (LDS) update on the new Auckland and Christchurch data, Vertical Datum 2016, building outlines and new Crown Property data.

The warmer weather is here, attracting more outdoor enthusiasts using our data to plan their pursuits! The need for Open Data continues and the LDS is not slowing with delivering it.

Thank you for responding to the building outlines survey, the data is being collated and a report will be made available in the next issue. We’d also love to hear your feedback on the LDS and any interesting stories about how you are using the data for future issues.

Christchurch Earthquake Survey Mark Movement Data

This data has been computed from cadastral and geodetic surveys carried out since the earthquakes. It details the movement of survey marks due to the Canterbury Earthquake Sequence, including the impact of the five major earthquakes on 4 September 2010, 22 February 2011, 13 June 2011, 23 December 2011 and 14 February 2016. Note that these movements apply only at the survey mark. Nearby land may have moved differently, especially in areas impacted by substantial shallow ground movement.
As well as Christchurch, the data covers Lyttelton, Spencerville, Kaiapoi, Pines Beach, Woodend, Pegasus and Waikuku Beach.

New Zealand Vertical Datum 2016

In June, LINZ released the New Zealand Vertical Datum 2016 (NZVD2016). It is the new official vertical datum for New Zealand, and replaces NZVD2009.

The NZGeoid2016 grid that defines NZVD2016 and the 13 local datum conversion grids are now available for download.

Building Outlines

The complete building outlines pilot data is now up on LDS. There have been over 4000 views of the dataset and more than 250 downloads. Already we have had some very positive feedback about the dataset.

We also received 45 responses from our user questionnaire about whether there would be value in establishing a national building outlines dataset. We are currently compiling a report of the results which will be available in January 2017.

Crown Property

The LINZ Managed Crown Property to Parcel association table is now live on LDS. This table can be used to link the LINZ Managed Crown Property dataset to parcel layers such as NZ Parcels, NZ Linear Parcels or NZ Primary Parcels, and is updated regularly to keep up with additions to or disposals from the property that LINZ manages.

New Zealand’s Crown estate includes some of the most iconic land in the country, ranging from South Island High Country pastoral land to bodies of water such as lakes Wanaka and Wakatipu. As the Crown’s land manager, we are the guardians of eight percent of New Zealand’s land area. We administer major sites such as the Waihi gold mine and Crown forestry licenses for land held for Treaty settlement.
