THETIS Project
Vision:
Information management in CZM is promoted through an
open
,
federated system
that facilitates resource sharing while maintaining
operational autonomy
for its members
Objectives:
On
-
line access
using WWW technology
Straightforward
plug
-
in / publishing
capability both for models and
data sets
Efficient search
for data and models via appropriate metadata
descriptions and a distributed search engine
Flexible data integration
using mediation techniques
Dynamic invocation of models
to produce data on demand
Interactive data visualisation
using GIS technology and
VR

CNR Contribution
Embedding of a 3D surface modelling program in the
THETIS system
digital topographic data of coastal areas (i.e. bathymetry,
coast lines, contours, ……) are merged in a suitable
geometric model able to capture the different morphological
shapes of coastal areas
Integration of advanced visualization tools in the
THETIS system
virtual reality techniques offer a transparent and easy

support for sharing GUI environments over the WEB
