Data Governance is the execution and enforcement of authority over the management of data and data-related resources.
See the interesting article on this subject here by Nicola Askham (an Independent Data Governance Coach).
A Spatial Data Infrastructure is the relevant base collection of technologies, policies and institutional arrangements that facilitate the availability of and access to spatial and business data. It covers the processes that integrate technologies, policies, standards, and people; the structure of working practices and relationships across data producers and users for access, sharing and analysing geospatial information across government and commerce. It also includes hardware, software and system components necessary to support the processes. Importantly, an SDI is not a central repository for data, a portal for discovery, view and download of data nor simply GIS software.
A Marine Spatial Data Infrastructure encompasses all marine and / or maritime information including maritime boundaries and limits, conservation areas and marine habitats, oceanography, bathymetry, geology, wrecks, offshore installations, pipelines and cables.

Our mapping data is available in digital form as either a Raster Chart in Geotiff format or in various GIS friendly vector formats e.g. GML, SHP, FGDB.
Raster Charts are simply digital images of standard nautical paper charts. This means that they only show the information available on the paper chart. Each pixel in the image represents a colour value so there is no intelligence in the raster image. Raster charts are created by scanning the paper chart.
Marine Themes Vector is an intelligent dataset. It is coded with additional information not available in paper or raster charts. It carries a wealth of geo-spatial data and is linked to a database of associated information. The user can click on different features, such as a shipwreck or buoy, and retrieve additional information about that specific feature. For example, a wreck appears only as an symbol on an raster chart, but in the vector data a user can click on the feature and see the additional information, such as depth, date sunk and cargo. Marine Themes Vector also provides the user with control over how the chart is displayed, so you can easily turn different layers of information on and off leaving you with a tailored map only showing the user the details that they require.

The work that OceanWise does in data management epitomises the way in which the hydrographic community should be moving in the twenty first century.
