Virtual Data Centre Metadata ProjectPutting endusers in direct contact with data owners via metadata web services

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)

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.

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
