Regional Geological Map Archive and Database
Database
Regional Geological Map Archive and Database (RGMAD) is a Nationally Significant Database and Collection. RGMAD is an archive of published and unpublished, hardcopy, digital image and digital GIS format file geological maps for New Zealand, its offshore territories and Antarctica.
Nationally Significant Databases are those datasets and collections registered as important for New Zealand, and as such are supported by long-term government funding.
Overview
RGMAD was recognised as Nationally Significant in 1992 during the formation of the Crown Research Institutes. GNS Science assumed custodianship of RGMAD, and under the QMAP geological mapping project has significantly enhanced the database through the use of GIS software. In 2009, dedicated funding was directed to establishing a digital image map catalogue, in order to increase accessibility and reduce handling of the precious legacy maps.
The oldest maps date back to the late 1800s and are notable for the painstaking production of the topographic base as much as for the superimposed geological information. Many of the archived geological maps are unpublished but contain information unavailable anywhere else. The unpublished maps include sheets recording field observations, preliminary compilations and advanced interpretations.
This resource is comprised of two collections.
- Historic Geological Map Archive: This is the pre-2012 component of the RGMAD resource. This complements the more recent digital geological maps available in the second collection.
- Geological Map of New Zealand collection: This is the post-2012 component of the RGMAD resource.
