|Abstract or Summary
- Basic research on semantic interoperability is just beginning to address support for
spatial data and information. This is clearly important for data portals containing
geographic information system (GIS) layers, as well as supplemental information, often
with cartographic and decision support tools. Agreements on content/semantic
interoperability of these resources can help to eliminate the problems of meaning, making
searches between disparate, but mutually beneficial, projects feasible. In recent years
significant momentum has occurred in the development of Internet resources for coastal
environments, where 2.2 billion people live within a 100 km range. A key aspect of this
trend has been the development of coastal web atlases, based on web-enabled GIS.
However, current inventories within coastal atlases are insufficient for the purposes of
networking between them. Each atlas has different classifications of data and information
(e.g., critical information on coastal erosion that may be needed across a broad
geographic region as supplied by several different atlases). New semantic web tools and
evolvement of standard metadata descriptions and interfaces are opening a road to
interoperate within atlases. This paper presents a new semantic mediation approach
using ontologies and Open Geospatial Consortium standard interfaces.
