Volcano Geological Mapping

Volcanic-focussed geological mapping began following the conclusion of the QMAP project and resulted in the production of the 1:60 000 Geological Map of the Tongariro National Park area and the initiation of a 1:120 000 map of the Taupo Volcanic Zone.

Geology of the Tongariro National Park area (GNSGM4)

The Tongariro National Park is a spectacular, active and diverse volcanic landscape. Within the park are several volcanic cones of varying age and states of preservation, including Hauhungatahi, Pihanga, Mount Tongariro, Mount Ruapehu and Mount Ngauruhoe. Despite their prominence in the landscape and history of the central North Island, no single map described the geological history and structure of the volcanoes within the park. To fill that gap, this map and text were produced through collaboration between GNS Science, the Department of Conservation and Victoria University of Wellington. The map and text are available for purchase from the Online Shop. 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 ArcGIS Server webservices. GIS layerfiles that reference and symbolise the web service layers are available for use in ArcGIS (ArcMap and ArcGIS Pro) and QGISMetadata describing the GIS data are also available.

A second edition of the Tongariro map was released in 2020 and incorporated new mapping of Tongariro. These data are available only via ArcGIS Server webservices. GIS layerfiles that reference and symbolise the web service layers are available for use in ArcGIS (ArcMap and ArcGIS Pro) and QGISMetadata describing the GIS data are also available.
