ICAN is a project of UNESCO IOC´s IODE Programme, and ICAN members seek to play a leadership role in forging international collaborations of value to the participating nations, thereby optimizing regional governance in coastal zone management and marine spatial planning.


We live on a blue planet, with oceans and seas covering more than 70 per cent of the Earth’s surface. Oceans feed us, regulate our climate, and generate most of the oxygen we breathe. Some 37 per cent of the world's population lives within 100 km of the coast. (UNEP)


CWAs are "...collections of digital maps and datasets with supplementary tables, illustrations, & information that systematically illustrate the coast, oftentimes with cartographic & decision support tools, all of which are accessible via the Internet."  O'Dea et al., 2007


Membership in ICAN is open to all interested parties who agree to the mission & objectives of ICAN, including those with an operational coastal web atlas, as well as those hoping to design and build a coastal web atlas in the future.

HydroView Now is a range of free to use web mapping services developed by SeaZone.  They have been developed for users building  and delivering coastal and marine atlases.  HydroView Now provides all the key base-mapping and reference features generally needed in developing marine and coastal atlases, allowing users to focus on their content and analysis.

HydroViewNow: Basemap and OpenStreetMap

Fully standards-based, the services work in web mapping applications as well as desktop clients such as ArcGIS and QGIS.  They comprise two services:  HydroView Now: Basemap and HydroView Now: Features.

HydroView Now : Basemap

A WMTS for global bathymetry.  This a cartographic product showing hill-shaded bathymetry alongside depth soundings derived from nautical charts.  It contains a transparent land-mask meaning it can be used alongside your choice of land mapping, e.g. OpenStreetMap or BingMaps

HydroView Now : Features

A WFS for global marine feature types.  This provides a definitive worldwide marine reference feature types derived from national hydrographic and other authoritative sources.  The content is processed to form a continuous vector layer dataset aligned to the draft IHO S-100 GML profile.

Both services are delivered through an authenticated web service interface, allowing users to consume the service via an application programming interface.  They are both deployed in the cloud delivering the performance and reliability that users are accustomed to with modern web mapping.
