This dataset is the geological mapping units of New Zealand. The datsets used are a product of the QMAP Geological Map of New Zealand Project and were produced by GNS Science. They represent the most current mapping of the geology of New Zealand at a scale of 1:250 000. The datasets are stored in an ESRI vector geodatabase and exported to Geoserver. The dataset comprises polygons with each polygon having attributes describing the type of geological unit, its content, name and age. This version of the data is currently being updated for release in mid 2016. In this interim version, the geological units in the South Island have been aligned with the current LINZ topographic data. The data structure complies with the GeoSciML Portrayal standard for GeologicUnitView and when finally released the fields required by that standard will be populated using the CGI Controlled Vocabulary (2012-11).
