This document discusses a pilot project to create a centralized metadata host for New Zealand geological and geophysical data. The project aims to (1) make publicly available metadata for multiple data types visible via clients like Google Earth, (2) connect end-users directly with data owners, (3) standardize metadata delivery across agencies and disciplines, and (4) test long-term viability of centralized metadata delivery for geophysical data. Example configurations and divisions of metadata are provided.

1. Virtual Data Centre Metadata Project
Putting endusers in direct contact with data owners via metadata web services
Dr Brad Ilg July 2010

2. GNS Science
Multiagency Virtual Metadata Workshop Goals
1. Agree on data types for which metadata will be collected
2. Discuss how metadata will be collected and stored (e.g. ArcSDE)
3. Discuss ANSLIC standard (“minimum metadata for geo data”)
4. Discuss metadata fields to be collected (e.g. type, date, owner)
5. Agree on how individual metadata fields will be described
6. Agree on common metadata format for each data type (i.e form)
7. Agree on common export format of metadata to clients (e.g. KMZ)

3. GNS Science
Pilot metadata project. Multiple agencies. Multiple disciplines.
The pilot metadata project has four primary goals:
• To render publicly-available NZ geophysical, geological and
physical geographical metadata visible via one or more clients.
• To put end-users in direct contact with data owners.
• To standardise metadata delivery.
• To test the possible long-term viability of centralised geophysical
metadata delivery.

6. GNS Science
Pilot project
This pilot project will use Google Earth and/or other clients to allow easy
visualisation of selected seismic, swath bathymetry, and sample metadata and
will provide links to the sources of these data.
• Develop KML metadata files of publically-available seismic and swath
bathymetry data (or other appropriate file format).
• Provide links to digital files of seismic and swath bathymetry data (host
location to be discussed).
• Provide digital images and grids of merged swath bathymetry data
(resolution to be discussed).
• The end goal of the pilot project will be to demonstrate application of
frontier basin screening techniques on a NZ basins/sub basin using a
wider array of data than typically available (i.e. test the product).

It’s all about visibility of data. Access to the data is
negotiated between data owner and industry client.
Initially
• Seismic reflection data (geophysical)
• Swath bathymetry data (geographical)
• Seafloor sample data (geological)
Eventually
• Gravity
• Magnetics
• Drill holes
• And other relevant data
