A key objective of this workshop, organised to coincide with Littoral 2012, is to present and collect feedback from the ICAN and wider coastal community on the latest version of the NETMAR/ICAN prototype interoperability platform (funded under FP7), which facilitates the connection of multiple atlases and the search and viewing of metadata and data. You will find out about the prototype functionality and will have the opportunity to provide input to assist development of the final version. You will also learn how to connect your own atlas to the platform and what resources are available to assist you in this task. Moreover, the utility of Web Processing Services and service chaining, used in other NETMAR application areas, will be demonstrated. This meeting also provides the opportunity to launch officially the IODE ICAN Pilot Project in the lead-up to its establishment as a full IODE Project which will be proposed to the 22nd session of the IOC Committee on International Oceanographic Data and Information Exchange (IODE-XXII) in March 2013. We will also explore stories on the use of coastal and marine atlases, based on the experiences of the African and Caribbean Marine Atlases. The workshop provides an opportunity to review and develop the ICAN draft work plan to be presented at IODE-XXII, as well as preliminary discussions on the themes to be the focus of the next workshop of the full ICAN community in June 2013 (to be held in Victoria, Canada). Attendance at the event is free and participants from outside the current ICAN community are most welcome, especially those currently using, or contemplating creation of, coastal or marine atlases. Please contact Ned Dwyer (n.dwyer@ucc.ie) before October 26th 2012 to reserve your place at the workshop.
