This collection of datasets has been superseded by a new edition (2nd edition, 2018) available here: https://data.gns.cri.nz/metadata/srv/eng/catalog.search#/metadata/43B63222-FCC9-4C1D-84EF-FC5FB2F4790F. This 1st edition has been kept as a historical archive and is available on request. The collection of datasets contains the 1:250 000 geological data for New Zealand. These datasets are a product of the QMAP Geological Map of New Zealand Project and were produced by GNS Science. At the time of publication they represented the most current mapping for New Zealand at a scale of 1:250 000. The datasets are stored in an ESRI vector geodatabase and exported to ArcGIS Server. The datasets comprises multiple geological features with each having attributes that describes them.

This collection of datasets has been superseded by a new edition (3rd edition, 2020) available here: https://data.gns.cri.nz/metadata/srv/eng/catalog.search#/metadata/5F6780CB-4135-4204-A2C8-50DD74B0466F. This 2nd edition has been kept as a historical archive and is available on request. This collection of datasets contains the 1:250 000 geological data for New Zealand. These datasets are a product of the QMAP Geological Map of New Zealand Project and were produced by GNS Science. At the time of publication they represented the most current geological mapping of New Zealand at a scale of 1:250 000. The datasets are stored in an ESRI vector geodatabase and exported to ArcGIS Server. The data structure complies with the GeoSciML 4.1 standard, where one exists, and uses the relevant CGI Controlled Vocabularies. The mapping frame of the majority of datasets is defined as 'surface geology', but some are either 'base of overlying geology' or 'top of basement'. 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.

This collection of datasets has been superseded by a new edition (4th edition, 2023) available here: https://data.gns.cri.nz/metadata/srv/eng/catalog.search#/metadata/3f6b15da-29a6-11ee-be56-0242ac120002.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 geodatabase holds the Geological Map of New Zealand dataset collection produced by GNS Science. The mapping frame within which the features have been observed is typically 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.
