A 25m grid of BASE carrying capacity for ALL leases (original model for all lease properties). This layer is buffered around the lease boundaries supplied by LINZ by roughly 5km to ensure that it can be reused for analysis where property boundaries are found to be incorrectly mapped or out-of-date.

Aspect (ASPECT180)

02 Oct 2012

This dataset was first added to LRIS Portal on 02 Oct 2012.

A 25m resolution grid of aspect in degrees north of south, for use as a regression variable for calculating BASE carrying capacity using Model 1 where:

if aspect <= 180 then aspect180 = aspect
else if aspect > 180 then aspect180 = 360 - aspect

This aspect data is symmetrical around north-south, meaning east and west are considered equivalent (90 degrees) to avoid problems in regression where normal aspect values of 0 and 360 degrees both equal the same north.

02 Oct 2012

This dataset was first added to LRIS Portal on 02 Oct 2012.

25m resolution grid of long-term mean annual solar radiation (NZMAS) for use as a regression variable for calculating BASE carrying capacity. NZMAS is derived from the LENZ underlying climate layer dataset. This grid has been resampled to 25m resolution using bilinear interpolation to deliver visually compatible apparent resolution as other input data sets used in the modelling process. For use with Model 2.

This dataset was first added to LRIS Portal on 02 Oct 2012.

A 25m grid of mean annual soil temperature at 30cm depth derived by regression analysis from 175 data loggers and NIWA standard climate stations recording soil temperature. This clipped version is provided for use as a regression variable for calculating the BASE carrying capacity. For use with Model 1.

A 25m resolution grid of mean vapour pressure deficit derived from the Land Environment New Zealand underlying climate dataset at an original resolution of 100m. This grid was resampled to 25m by bilinear interpolation to have visually compatible resolution to other data sets being used in modelling of BASE carrying capacity. For use with both Model 1 and Model 2.

Vapour pressure deficit (VPD) is the meteorological variable used to quantify the drying power of the atmosphere. The VPD estimates the difference (or gradient) in vapour pressure
(concentration of water vapour) between the moist vegetation and the drier atmosphere above.

Moderate VPD is beneficial to plants, helping to drive photosynthetic processes, but extreme
and/or prolonged high VPD will stress plants and negatively effect productivity.

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).

This is a binary mask layer identifying all areas that by definition (e.g., forested or water body) should have BASE carrying capacity set to zero (0 stock units/ha). All other areas are set to one (unity). The final BASE carrying capacity is derived by multiplying the result of the regression models by this binary mask leaving model values either unchanged or reset to zero. For use with both Model 1 and Model 2.
