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
-

Virtual Reality for Geodata


VR, as a tool for
simulating

the real world rather then for
imitating

it, is
a suitable graphical interface for navigating spatial data and supporting
users in decision
-
making processes or exploratory data analysis



VRML: Virtual Reality Modeling Language


Standard language for representing VR worlds


Support for modelling of geometry
and

interactions


Sharable and platform
-
independent

VRML is a suitable support for building GUI for geodata


Cost effective (generally, VR plug
-
ins are freeware)


Easy to use
