This dataset was first added to Koordinates on 29 May 2010.

Slope data layer used in the creation of Land Environments of New Zealand (LENZ) classification. The classification layers have been made publicly available by the Ministry for the Environment (see data.mfe.govt.nz/layers/?q=LENZ for to access these layers).

This slope data layer is measured in degrees and was created from a 25-metre digital elevation model (DEM) fitted to 20-m digital contour data derived from New Zealand's NZMS 260 map series using in-house software developed at Landcare Research.

All contours were originally derived photogrammetrically from stereo photographs for final map reproduction at a scale of 1: 50 000. Additional intermediate contours and spot heights were used in generating the DEM where available, while coastlines and shorelines (for lakes greater than 10 ha in extent) were used to constrain the DEM surface around water bodies. The linear interpolation method used to create the DEM threads contours through the cells before interpolation so that any cell intersected by a contour will be given the elevation value of that contour, leading to a high percentage of cells with elevations that are multiples of 20 or 10 in steep areas.

Additional details are defined in the attached LENZ Technical Guide.

Christchurch 15m DEM - Height Corrected

25 Feb 2011

This dataset was first added to Koordinates on 25 Feb 2011.

A 15 metre resolution, floating point precision, elevation grid generated from the LINZ 1:50,000 scale Topographic data layers (20m contours, spot heights, lake shorelines and coastline) using Landcare Research's in-house interpolation software.

This DEM was originally produced in New Zealand Map Grid (NZMG) projection with elevation in terms of the Infomap 260 chart datum (Mean High Water Spring).

It has been transformed so that the heights are floating point ellipsoidal heights with respect to the GRS80 ellipsoid; this is the standard ellipsoid for the NZTM projection.

NZSoSDEM v1.0 is a Digital Elevation Model (DEM) covering the whole of New Zealand at a spatial resolution of 15m, created by the School of Surveying by interpolating LINZ topographic vector data.

The DEM was created as a series of 30 maps which extent correspond exactly with the LINZ Topo250 topographic map series. Smaller regions can thus be obtained individually but also fit together seamlessly to create a full countrywide DEM.

The accuracy of this product was comprehensively assessed using a statistically sound selection of 3791 check points throughout the country. The comparison of results with other available country-wide DEM demonstrate an improvement of NZDEM_SoS_v1.0 in terms of quality that comes in addition with a finer spatial resolution.

A full description of the interpolation/assessment process can be found in the attached documentation: Columbus, J.; Sirguey, P. & Tenzer, R. (2011), 'A free, fully assessed 15-m DEM for New Zealand', Survey Quarterly 66, 16-19.
