Description: Coastal mapping plays an important role in informing marine spatial planning, resource management, maritime safety, hazard assessment and even national sovereignty. As such, there is now a plethora of data/metadata catalogs, pre-made maps, tabular and text information on resource availability and exploitation, and decision-making tools. A recent trend has been to encapsulate these in a special class of web-enabled geographic information systems called a coastal web atlas (CWA). While multiple benefits are derived from tailor-made atlases, there is great value added from the integration of disparate CWAs. CWAs linked to one another can query more successfully to optimize planning and decision-making. If a dataset is missing in one atlas, it may be immediately located in another. Similar datasets in two atlases may be combined to enhance study in either region. But how best to achieve semantic interoperability to mitigate vague data queries, concepts or natural language semantics when retrieving and integrating data and information? We report on the development of a new prototype seeking to interoperate between two initial CWAs: the Marine Irish Digital Atlas (MIDA) and the Oregon Coastal Atlas (OCA). These two mature atlases are used as a testbed for more regional connections, with the intent for the OCA to use lessons learned to develop a regional network of CWAs along the west coast, and for MIDA to do the same in building and strengthening atlas networks with the UK, Belgium, and other parts of Europe. Our prototype uses semantic interoperability via services harmonization and ontology mediation, allowing local atlases to use their own data structures, and vocabularies (ontologies). We use standard technologies such as OGC Web Map Services (WMS) for delivering maps, and OGC Catalogue Service for the Web (CSW) for delivering and querying ISO-19139 metadata. The metadata records of a given CWA use a given ontology of terms called local ontology. Human or machine users formulate their requests using a common ontology of metadata terms, called global ontology. A CSW mediator rewrites the user’s request into CSW requests over local CSWs using their own (local) ontologies, collects the results and sends them back to the user. To extend the system, we have recently added global maritime boundaries and are also considering nearshore ocean observing system data. Ongoing work includes adding WFS, error management, and exception handling, enabling Smart Searches, and writing full documentation. This prototype is a central research project of the new International Coastal Atlas Network (ICAN), a group of 30+ organizations from 14 nations (and growing) dedicated to seeking interoperability approaches to CWAs in support of coastal zone management and the translation of coastal science to coastal decision-making.

Description: From June 16th to 17th, 2013, the International Coastal Atlas Network (ICAN) held a workshop on “Expanding Participation in Coastal Web Atlas Development and Use”, at the University of Victoria, British Columbia, Canada. The workshop (aka “ICAN 6”) engaged 29 participants from 9 countries, representing 22 organizations and multiple areas of scientific and technical expertise. This meeting was a follow-up to the successful 2011 workshop on “Coastal Atlases as Engines for Coastal & Marine Spatial Planning” (aka “ICAN 5”) held in Oostende, Belgium, as well as workshops in 2009, 2008, 2007 and 2006. ICAN 6 provided an opportunity to discuss how the ICAN community could take advantage of now being an IODE project, to share its knowledge and aid capacity building among IOC member states in relation to coastal and marine data management. Moreover, ICAN has seen its membership grow in the last two years and given its extensive membership along the North and South American Pacific coasts it was a great opportunity to hear about atlas developments in those regions. Key activities at the workshop included: exploring the opportunities for ICAN in an IODE context and how to build synergies with other IOC projects; the activities of the Ocean Biogeographic Information System (OBIS) project of the IOC were presented as well as IOC’s ICAM programme which highlighted how data management tools developed within ICAN can contribute to the goals of ICAM. Beyond the IOC, activities within the Group on Earth Observations’ (GEO) Coastal Zone Community of Practise (CZCP) are very relevant to ICAN, in particular the objective to develop a global coastal zone information system (CZIS). ICAN can help inform the development of such a CZIS. discussion of coastal atlas training needs and how ICAN members can contribute; in particular the training requirements of the African Coastal and Marine Atlas, and the Caribbean Marine Atlas were discussed. An overview of IODE training activities was presented and linkages on training between ICAN and ICAM related projects (e.g. SPINCAM II) were discussed. ICAN should also take advantage of the OceanTeacher platform developed by IODE. Atlas Stories – presentations from Atlas developers and users from North and South American Pacific coasts and beyond; the ICAN 6 Atlas Stories focused on CWA development around the Western Pacific Rim presenting new activities as well as updating the network on recent upgrades to previously discussed CWAs. The session started with the South American SPINCAM project which is developing atlases across five countries, followed by updates on the Oregon Coastal Atlas and the Washington State Coastal Atlas. Workshop participants also learned about Canada’s CanCoast and ShoreZone and the session concluded with the introduction to SmartAtlas through the African Coastal & Marine Atlas experience. a small “workshop within a workshop” for atlas technical developers on how to become a new node in the ICAN interoperability portal, version 3; The latest version has multilingual search capability, semantic search and the ability to connect directly to map services and display the results in a map. It was agreed that the current interface will be upgraded to HTML5 in the coming period. a small “workshop within a workshop” focussing on Volunteered Geographical Information (VGI) and its implications for coastal atlases; within the EEA, systems have been developed using both crowdsourcing and citizen science approaches. SeaSketch is a software platform intended as an end-to-end mapping solution for marine spatial planning, which allows anyone, regardless of their technical abilities, to sketch prospective management plans and receive analytical feedback on the consequences of their designs. The Marine Regions project aims to develop a standard for georeferenced marine names and there is potential to link it to the ICAN portal. Esri is introducing the concept of a “living Atlas” which is delivered via ArcGIS Online (AGOL). ICAN members can take advantage of this concept by using it to leverage their existing Atlas holdings or by using the platform to build a new Atlas quickly. development of an ICAN work plan for the period 2013-2015; this included plans for developing a communications strategy, a handbook on how atlas developers and users can interact and building synergies with other IOC and non-IOC projects. It also looked at developing a coastal atlas training plan. At its core ICAN supports atlas development and interoprerability approaches, therefore the Technical Committee presented its plans for developments in the next two years. The workshop concluded with the first face-to-face meeting of the new Steering Group, which was put in place after ICAN became an IODE project. This meeting saw two new members join the SG and leaders for the various work plan elements were appointed. Since ICAN 6 there have been developments in relation to the work plan. A revised plan and associated budget request was submitted to the IODE Officers meeting held in March 2014. As IODE has a limited budget and a number of projects to support, not all work plan items will receive funding, however the funding allocated will be of significant assistance to maintain ICAN and help progress its work. ICAN is now on a sound footing as part of the IODE family of projects, although members should continue to seek funding from other sources to advance the key technical activities. This ambitious work plan will require the commitment of all members to ensure that it can be implemented. A priority for 2014 is the redevelopment of the web site in order to make it easier to navigate and more responsive to user needs. Interoperability remains a core activity of ICAN and the technical committee has proposed a number of activities to progress further the developments in this area. A key technical concept which emerged at ICAN 6 was that of an “atlas-in-a-box”. The idea is that a new atlas developer can get started quickly on implementing and publishing a CWA with a minimal amount of technical/programming knowledge. The committee intends to scope the feasibility of such a development based on potential solutions such as SmartAtlas and ArcGIS Online. We would like to thank Rosaline Canessa and her team at the University of Victoria for their warm welcome and excellent hosting of ICAN-6 and we look forward to seeing you at the 7th International workshop (aka ICAN 7) which will be hosted by CSIR at Stellenbosch in South Africa from April 20th to 21st 2015, just before CoastGIS 2015

Description: In recent years significant momentum has occurred in the development of Internet resources for decision makers and scientists interested in the coast. Chief among these has been the development of coastal web atlases (CWAs). While multiple benefits are derived from these tailor-made atlases (e.g., speedy access to multiple sources of coastal data and information), the potential exists to derive added value from the integration of disparate CWAs, to optimize decision making at a variety of levels and across themes. This paper describes the development of a semantic mediator prototype to provide a common access point to coastal data, maps and information from distributed CWAs. The prototype showcases how ontologies and ontology mappings can be used to integrate different heterogeneous and autonomous atlases, using the Open Geospatial Consortium’s Catalogue Services for the Web.
