and video. Data models are implemented in software program codes,
that usually need visualization tools to represent their results .
“The lack of transparent integration means that data is not practically
available for integrated problem solving. lncreasingly, solutions to problems require data from several disciplines, and also from different
regions and countries. One application area where data integration and
visualization is particularly needed is in Coastal Zone Management
(CZM) and the prototype system will focus on supporting CZM of the
Mediterranean Region of Europe. (Quoted from: http://www.ics.forth.gr/

Using the Internet to connect users to a distributed collection of information systems, the main elements of the architectural framework are.
- Web-based access to databases of various kinds, as this provides a
simple way to access information of various kinds (HTML documents,
images, video and audio) and provides a transparent interface to the users
to browse the various information sources. HTML documents can act as
indexes to information sources for a large distributed system and
extensions to XML should be possible;
- Invoking existing applications, such as simulations, data visualization, GIS related data interpretation, and graphical tools, along with the
various (,IS tool collections, invoked via the Web. (,http://www.iacm.
gr/gaea);
- Access to legacy databases, via the Web, which already contain various
information, both georeferenced data and images, that store the required
coastal information, including data stored in/by Illustra, Sybase, Oracle
and Arc/Info;
- Integrate existing services for indexing, searching and access with
data repositories and GIS information such as areas/regions of maps
selected by the user, via a Dienst 4.0 server ( http://cs-tr.cs.cornell.edu/
Dienst/htdocs/ document_menu.html) and a Disco. Metadata standards for
digital geospatial metadata such as those of the US Federal Geographic
Data Committee (FGDC) will be used ( http://www.blm.gov/gis/meta/barney/meta_sections3.html), which provide definitions for a number of fields,
along with their relations within a hierarchical structure. Another
standard, the Usmarc, is used for analog and digital geospatial data.

- An interface is provided for information sources that provide data
and image collection services common to all users. The goal is to integrate existing technologies within the common platform, i.e. the Web,
