NZL GNS 1:1M Geology. 2nd edition

This collection of datasets contains the 1:1 000 000 geological data for New Zealand. These datasets are a product of the Geological Map of New Zealand 1:1 000 000 project and were produced by GNS Science. They represents the most current mapping of the geology of New Zealand at a scale of 1:1 000 000. The datasets are stored in an ESRI vector geodatabase and exported to ArcGIS Server. The datasets comprises separate feature classes describing the geology.
The mapping frame for 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 +/- 1000 m.
The datasets are 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. (The author)
