This layer depicts estimated sediment/soil loss across New Zealand and was created using the NZeem erosion model. Erosion control is defined as the prevention of soil loss by an ecosystem. NZeem has been calibrated from sediment discharges measured in New Zealand rivers (Dymond et al., 2010). This model estimates the long-term mean erosion rate from all...

Mean annual erosion rates (tonnes of soil/km2/yr) in the South Island of New Zealand under current landcover generated from EcoSat Woody (2001-2003). This layer is not available for download on LRIS. If you are interested in downloading that layer, please contact John Dymond. Reference: John R. Dymond, Harley D. Betts, Christina S. Schierlitz, An erosion...

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 erosion attribute of the NZLRI.

This provides a polygon coastline and islands layer which is based on the Topo50 products. It is a combination of the following layers: NZ Coastlines (Topo 1:50k) NZ Island Polygons (Topo 1:50k) NZ Auckland Is Island Polygons (Topo, 1:50k) NZ Campbell Is / Motu Ihupuku Island Polygons (Topo, 1:50k) NZ Antipodes Is Island Polygons (Topo, 1:25k) NZ Kermadec...

Coastal Erosion Hazard Zones show the extent of Northland coastlines that are potentially susceptible to coastal erosion.This service shows the location of Coastal Hazards from the 2017 assessment and includes coastal run-up hazard, coastal flood hazard and coastal erosion hazard.

Wellington City Corrosion Zone as determined by NZS 3604:2011. Corrosion Zones relate to the severity of exposure to wind-driven salt, with B being low risk, C medium risk and D high risk (Category A is not applicable in New Zealand). The Wellington City territory authority area is located in zone C aside from the coastal zone. For this reason the coastal...
