Regional Geology Map Archive & Database

• A collection of original data sheets, field compilations and overlays of published geological maps from 1865

• Also contains reports and field notes/records covering field observations and geological information

• Includes data on sites now destroyed, drowned, or lost by weathering and erosion.

• These data are regularly searched for modern map compilation

QMAP 1:250 000 Geological Map of New Zealand

• ….Quarter million MAP

• Replaces first edition of the 1960s

• Incorporates new concepts (plate tectonics, terranes etc)

• Synthesises existing geological mapping

• New field work in poorly known/understood areas

• Publish a series of 21 maps

• FRST funded

QMAP 1:250 000 Geological Map of New Zealand

• Build a GIS database of NZ geology

• ArcInfo GIS software

• Information as layers (points, lines, polygons)

• Database design in 1994 - little subsequent modification

• “Flat-field” structure

• Minimal abbreviation and coding

• Currently metadata poor

• Data-rich attributes

• Complete sheet by sheet compilation (c. 2009 through FRST funding)

• Edgematch, update earlier sheets and make seamless (c. 2010 through FRST funding)

• Move to ArcSDE Oracle environment

• Integrate with GNS/GSNZ databases (e.g. StratLex, Bibliographic)

• Serve to public at cost-of-retrieval or free via Web

• Maintain and update to keep “live” - funding required
