New Zealand Environmental Data Stack (NZEnvDS) comprises a set of 72 spatial layers for environmental modelling and site characterisation. NZEnvDS includes the layers that informed the Land Environments of New Zealand (LENZ), additional layers generated for LENZ that were never publicly released, and additional layers generated since, all covering mainland New Zealand and surrounding inshore islands. The original/top copy of the dataset is available at (doi.org/10.7931/m6rm-vz40), but the layers are reproduced here for ease of access. See (newzealandecology.org/nzje/3440/) for a publication describing NZEnvDS. A measure for how exposed a location is to potential winds from all directions. The unit is a dimensionless index with values below 1 indicating wind shadowed areas, and values above 1 indicating wind exposed areas. Calculated from the NZEnvDS “elevation” DEM and the SAGA Morphometry module in SAGA GIS version 7.3.0.

See (newzealandecology.org/nzje/3440/) for a publication describing NZEnvDS. Generating using a geomorphon algorithm, which uses pattern recognition concepts to classify terrain based on a DEM. Individual pixels are allocated to one of the following 10 values:

  1. flat
  2. summit
  3. ridge
  4. shoulder
  5. spur
  6. slope
  7. hollow
  8. footslope
  9. valley
  10. depression.

Generated using r.geomorphon (Jasiewicz et al. 2013; Jasiewicz & Stepinski 2013) in GRASS GIS (Neteler et al. 2012). The NZEnvDS variable “elevation” was used as the DEM input.

Calculated from “elevation” using the terrain function in the raster R package (Hijmans 2017). topo_flowDir values are encoded as powers of 2 (0 to 7). The cell to the right of the focal cell 'x' is 1, the one below that is 2, and so on (Hijmans 2017):

Generated using a quantile regression forest model with pH data from over 6,000 soil samples collected across New Zealand, and a set of environmental covariates (Roudier et al. 2020). Note that this layer has been masked to exclude urban areas and terrestrial areas without soil (e.g. rock).
