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.

This dataset was first added to LRIS Portal on 13 Oct 2011.

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.

This dataset was first added to LRIS Portal on 13 Oct 2011.

The PRISM instrument is carried on the Japanese ALOS satellite and has three sensors that provide forward, nadir, and aft-looking views of the terrain. The forward and aft views can be combined to give stereo coverage with approximately a one-to-one base-to-height ratio, which is almost ideal for generating terrain information. The nominal spatial resolution of the ALOS-PRISM imagery is 2.5m in the forward, nadir and aft directions.

Stereo imagery has been acquired of a region in Wanganui/Manawatu area of the North Island of New Zealand. This area is currently being studied for automated soil mapping, using a variety of technologies.

This DEM represents a draft version to demonstrate progress on DEM generation from PRISM. Further developments in processing, calibration and validation are required before production of acceptable DEMs is possible.
