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 digital elevation model (DEM) indicating the elevation above sea level. This layer was generated by combining the New Zealand Digital Elevation Model (NZDEM; Barringer et al. 2002) tiles from the 25 m resolution North Island (Land Information New Zealand 2020c) and South Island (Land Information New Zealand 2020d) data sets, and resampling to the LENZ 100 m grid (Leathwick et al. 2002) using bilinear interpolation.

See (newzealandecology.org/nzje/3440/) for a publication describing NZEnvDS. 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).

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):
