This dataset was first added to LRIS Portal 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.

The NZLRI is a spatial database containing about 100,000 polygons (map units), each of which describes a parcel of land in terms of five characteristics or attributes (rock, soil, slope, erosion, vegetation). This layer represents a GIS dissolve on the slope attribute of the NZLRI.

Soilscapes are defined as "a landscape unit including a limited number of soil classes that are geographically distributed according to an identifiable pattern". These first approximation soilscapes are derived from legacy data and expert knowledge.

This data layer was derived from terrain analysis of a 25 m resolution national digital terrain model to create a setof landform elements. The landform elements are derived from a fuzzy classification based on local geometry (curvature and slope) and landscape context, and provide a primary foundation for mapping soil distribution in steepland land systems, which significantly improves knowledge of soil distribution on hillslopes in complex landscapes, and over a wide range of land systems.

A 25m resolution grid based on Land Use Capability class where class numbers 1 to 8 have been substituted by regression coefficients. This grid is provided as a regression variable for calculating BASE carrying capacity for ALL high country leases other than those in the Mackenzie basin (i.e. for use with Model 1).
