National Shallow Groundwater Presence-Absence
This dataset identifies areas potentially exposed to shallow groundwater hazards. The model developed to create this product was trained using all accessible groundwater depth information held in Regional Council and Territorial Authority databases and in the New Zealand Geotechnical Database. This comprised readings from approximately 110,000 locations around the country. Our team spent 300 hours collating and processing these data and is currently publishing the output database so that other researchers and practicing scientists and engineers can benefit from the mahi.
