New Zealand Hydrogeological Systems

This hydrogeological system GIS dataset provide a nationally-consistent basis for hydrogeological mapping in New Zealand. Hydrogeological systems are defined here as geographical areas with broadly-consistent hydrogeological properties, and similar resource pressures and management issues. The ‘NZ_hydrogeologicalsystem_polygon.shp’ provides seven hydrogeological attributes as follows: unique name (HS_name), unique identification (HS_id), system type (HS_type), coastal information (HS_coast), aquifer overview (HS_overview), geology and age group (HS_geo_gr) and geology and age descriptor (HS_geo_age). Nine system types are identified (see figure below). The ‘NZ_hydrogeologicalsystem_boundary.shp’ attribute table identifies, the source and methods of boundary delineation. Attribute names, descriptions and values for both datasets are detailed in Moreau et al. 2019. DOI: https://doi.org/10.21420/HTZ8-Z141 Cite as: GNS Science. (2018).
