1:250 000 Geological Map of New Zealand (QMAP)

The QMAP project completed the last of 21 new 1:250 000 geological maps in 2012. The maps cover all of New Zealand and their accompanying texts describe each area’s geomorphology, stratigraphy, tectonic history, geological resources, geological hazards and engineering geology in general terms. The maps and texts are available in printed hardcopy and digital equivalents through the Online Shop.

In 2014 the digital versions of the 21 individual QMAPs were stitched together into a single seamless GIS dataset, and released as the GNS Science Geological Map 1 - Geological Map of New Zealand 1:250 000 (1st edition). These data are viewable through a web map application. In 2018, an enhanced data structure was adopted that complied with the GeoSciML-Lite package of the GeoSciML 4.1 data model and data transfer standard, and incorporated relevant CGI Geoscience Vocabularies terms. These data were released as GNS Science Geological Map 1 - Geological Map of New Zealand 1:250 000 (2nd edition).

The second edition is only available in digital form. GIS users can purchase the digital data which come with ready-built map projects for ArcMap and the free ArcReader and QGIS software. These data also can be accessed via GeoServer and ArcGIS Server webservices. GIS layerfiles that reference and symbolise the web service layers are available for use in ArcGIS and QGIS. Metadata describing the GIS data are available.
