This Web Feature Service (WFS) provides access to the geological features that form part of the 1:1 250 000 Geological Map of New Zealand (2nd edition). It is a product of the Geological Map of New Zealand project and was produced by GNS Science. The data structure complies with the GeoSciML 4.1 standard where possible and uses the relevant CGI Controlled Vocabularies.

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 +/- 250 m.
