A raster ArcGIS grid that defines the elevation of the basal surface of the Early to Middle Pleistocene geological unit. It has been derived from the 3D geological model of the Napier-Hastings urban area which forms part of GNS Geological Map 7. The 3D model was built using Leapfrog Geo software. This dataset forms part of Begg JG, Jones KE, Lee JM, Tschritter C. 2022. 3D geological model of the Napier-Hastings urban area [digital data]. Lower Hutt (NZ): GNS Science. (GNS Science geological map; 7b). https://doi.org/10.21420/JJEC-J652. The explanatory text associated with this dataset is available from https://doi.org/10.21420/QFEK-9369.

A Gocad T-surf mesh that defines the volume of the Murihiku-Dun Mountain-Maitai terranes geological unit. It has been derived from the 3D geological model of the Pukekohe area which forms part of GNS Geological Map 12. The 3D model was built using Leapfrog Geo software. This dataset forms part of Jones KE, Strogen DP, Hill MP. 2022. 3D geological model of the Pukekohe area [digital data]. Lower Hutt (NZ): GNS Science.

A 3D geological model of the Napier-Hastings urban area that forms part of GNS Geological Map 7, developed in Leapfrog Geo software and available on request. The 3D geological model provides a conceptual three-dimensional representation and interpretation of the near-surface and subsurface geology including the thickness and geometry of stratigraphic and lithostratigraphic units, geometry of major faults, and drillhole and topographic data.
