See explanatory slide (slide 2) inserted June 2017. This presentation was created between my secondment from GNS Science, A New Zealand Government Research Institute, to the Ministry of Economic Development (MED) and my eventual employment at MED. The pilot work was proposed and led by me. It involved MED, GNS Science, The National Institute of Water and Atmospheric Sciences, Land Information New Zealand and Google. It was published as part of the PEGI Project on GNS Sciences Petroleum Basin Explorer. I went on to propose a more ambitious project entitled the "Multiagency Virtual Marine GeoData Centre Metadata Project.” The goal was to provide a central portal from which all marine data could be located, visualised and whose ownership and custodianship would be evident. This presentation summarises that proposal.

Putting end-users in direct contact with data owners via metadata web services

2. Explanatory slide
inserted June 2017
This presentation was created between my
secondment from GNS Science, A New Zealand
Government Research Institute, to the Ministry
of Economic Development (MED) and
myeventual employment at MED.
The pilot work was proposed and led by me. It
involved MED, GNS Science, The National
Institute of Water and Atmospheric Sciences,
Land Information New Zealand and Google. It
was published as part of the PEGI Project on
GNS Sciences Petroleum Basin Explorer.
I went on to propose a more ambitious project
entitled the New Zealand Marine Geophysical,
Geological, Geochemical and Geographical
Virtual Metadata Project. The goal was to
provide a central portal from which all marine
data could be located, visualised and whose
ownership and custodianship would be evident.

3. 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)
Multiagency Virtual Marine GeoData Centre Metadata Project

4. 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.
Pilot metadata project. Multiple agencies. Multiple disciplines.

Geography
•Swath bathymetry
•topography
Geology
•Bottom samples
•Seep maps
•PETLAB
•FRED
Geophysics
•Seismic
•Gravity
•Magnetics
•Magnetotellurics
Geochemistry
•Water column samples
•Rock samples
Oceanography
•Currents
•Temperature
•Slick maps
•Waves

7. 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).

11. The NZ standard for
metadata collection
Multiagency Virtual Marine GeoData Centre Metadata Project

12. Initially
• Seismic reflection data
• Swath bathymetry data
Eventually
• All marine geophyics
• All marine geology
• All marine ecology
• All oceanography
• And other relevant data
It’s all about public visibility of
metadata. Access to the data is
negotiated between data owner
and/or custodian and client.
