The January 2012 Newsletter of UNEP GRID/Arendal's Marine Division features two excellent resources, OCEANIDS and OSDS Data Inventory Map (the featured Map of the Month).
The first, OCEANIDS, is “a new tool to find and examine public marine-related scientific datasets. A main aim in the development of OCEANIDS is to provide end users with an interdisciplinary and multi-thematic geospatial and metadata portal of public data and information – but with the non-GIS expert end user in mind.” For more on how this is accomplished with Geocommons solutions, see the newsletter.
The second resource, the One Stop Data Shop (OSDS) Data Inventory Map “shows all the cruise track lines and point databases that have been collected during the lifespan of the Continental Shelf Programme, and constitutes the world’s largest collection of geophysical metadata relevant for working on delineation of extended continental shelves (ECS) beyond 200 nautical miles.” The map includes “URLs leading to the actual data holder's web pages for that object. Furthermore, the map shows the status of all ECS Submissions received by the Commission on the Limits of the Continental Shelf. In January 2012 Tanzania was the 59th submission.
As the newsletter announces, the ECS inventory map “is also available for Google Earth as separate layers.”
