  • NitrateWatch project (SSIF Project 6) is gathering nitrate data from around New Zealand. Our goal is to provide this information visually to our stakeholders via a map interface • NitrateWatch is aimed at generating new knowledge about nitrates in rural drinking water across New Zealand. • We aim to highlight nitrate hot spots and benchmark nitrate levels for rural drinking water by collecting data from drinking water samples submitted by rural residents. • A further goal is to improve stakeholder engagement through working more closely with iwi, Regional Councils, district Councils, Government agencies and local communities in readiness for future cooperation. • Data generated from this project serves as a talking point to showcase GNS’ leadership in the groundwater/drinking water space. • Our data provides future opportunities for GNS groundwater staff to build new projects leveraged off NitrateWatch

  • This dataset contains the bounding arcs to the 1:1 000 000 geological units data for New Zealand. The dataset is a product of the Geological Map of New Zealand 1: 1 000 000 project and was produced by GNS Science. It represents the most current mapping of the geology of New Zealand in a single dataset at a scale of 1:1 000 000. The dataset is stored in an ESRI vector geodatabase and exported to ArcGIS Server. The dataset comprises arcs with each arc having attributes describing the type of contact, its name, exposure and accuracy. It complies with the GeoSciML Portrayal standard for ContactView. The outcrop surface (map horizon) on which the features are mapped is the Earth surface. The fields required by the GeoSciML Portrayal standard were populated using the CGI Controlled Vocabulary (2012-11). The data should not be used at scales beyond that for which it was prepared. The spatial accuracy is estimated to be no better than +/- 1000 m. The dataset is available for purchase as feature classes in ESRI file geodatabase and shapefile GIS formats and freely consumable as a layer in Web Map Services and Web Feature Services from ArcGIS Server.

  • This dataset has been superseded by a new edition (4th edition, 2023) available here: https://data.gns.cri.nz/metadata/srv/eng/catalog.search#/metadata/3f6b15da-29a6-11ee-be56-0242ac120002. This dataset represents the resources present at or near the surface and comprises points with attributes describing the type of resource. The dataset is part of the Geological Map of New Zealand collection produced by GNS Science and represents a slightly updated selection of the data available from the Geological Resource Map of New Zealand (GERM) dataset. The mapping frame within which the features have been observed is defined as surface geology (i.e. the bedrock and superficial deposits that are exposed at the topographic surface or would be visible if the overlying soil was removed). The data structure complies with the GeoSciML 4.1 standard, where relevant, and uses the appropriate CGI Controlled Vocabularies. The dataset is associated with Heron, D.W.

This 2nd edition has been kept as a historical archive and is available on request.. This dataset is the lineament data for New Zealand. The dataset is a product of the QMAP Geological Map of New Zealand Project and was produced by GNS Science. At the time of publication it represented the most current mapping of linears for New Zealand in a single dataset at a scale of 1:250 000. The dataset is stored in an ESRI vector geodatabase and exported to ArcGIS Server. The dataset comprises arcs with each arc having attributes describing the accuracy of location and type of lineament. The data structure complies with the GeoSciML 4.1 standard where relevant and uses the appropriate CGI Controlled Vocabularies. The mapping frame is defined as 'surface geology'. The data should not be used at scales beyond that for which it was prepared. The spatial accuracy is estimated to be no better than +/- 250 m.

  • Raster files and contours of apparent resistivity collected at nominal electrode array spacings of 500 and 1000 m. DC resistivity mapping data collected by GNS Science and its predecessor organisations from the mid-1960s until 1997, primarily for geothermal exploration. Apparent resistivity varies by several orders of magnitude in the Taupō Volcanic Zone, where there is a significant resistivity contrast between rocks saturated with hot geothermal fluids and cold, siliceous volcanic rocks. Over 32,000 DC resistivity mapping observations have been made in New Zealand. The greatest number of measurements are in the Taupō Volcanic Zone, with some smaller surveys in the Waihi area and Ngawha in Northland. All data collected since 1970 have been with the Schlumberger electrode configurations with nominal electrode spacings of AB/2 = 500m and AB/2 = 1000m. Prior to 1970, DC resistivity data were mostly collected using a Wenner array with electrode spacing 1800 ft (549 m) and 3600 ft (1097 m). Data collected in Lake Taupō used two 150 m long dipoles towed behind small boats, each boat separated by 500 m forming an equatorial dipole-dipole array.
