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

THETIS Demonstrator Scenarios

Waste Transport, for the simulation of pollution point sourcesgeneral circulation data, concentration of effluents, transport of pollutants

Tracking of Sea Structures, for the study of the dynamic of oceansoceanographic structures

Nearshore and Offshore Waves, for coastal defences, coastal and offshore structures, flood prevention, etc

Calculation of the wave climate based on historical wind and wave dataEstimation of directional (2D) spectra of surface waves based on heave-pitch-roll

time series


IMA-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-to-use support for sharing GUI environments over the WEB

Virtual Reality

Virtual RealityComputer interface technology for the interaction with real-time 3D virtual environments in a more intuitive manner

Virtual Environmentsrealistic,interactive and immersive simulations of places and scenes


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

Conclusions and Future Work

THETIS: data and program sharing system

Full embedding of the surface modelling module in the THETIS system, with integration with the GIS user interface of THETIS

VR to support data visualization together with traditional GIS tools

Extend the interaction capabilities with VR-DTM
