7 Michela Spagnuolo Istituto per la Matematica Applicata International Projects related to Spatial Data Handling High-quality surface modelling Consultancy Research Contract between IMA-CNR and Monolith co Ltd, Tokyo, Japan ( ) surface modelling model compression uncertainty coding shape analysis

8 Michela Spagnuolo Istituto per la Matematica Applicata International Projects related to Spatial Data Handling THETIS: a Data Management and Data Visualisation System for Supporting Coastal Zone Management of the Mediterranean Sea TELEMATICS, Project F0069, Starting: 1 st July 1998 (30 months) ICS-FORTH, Greece (Leader Contractor) ERCIM, France INRIA, France University of Crete, Greece IACM-FORTH, Greece Space Alcatel, France HR WALLINGFORD, UK RECORMED-NTEWORK, France IMBC, Greece IMA-CNR, Italy

9 Michela Spagnuolo Istituto per la Matematica Applicata 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: FOn-line access using WWW technology FStraightforward plug-in / publishing capability both for models and data sets FEfficient search for data and models via appropriate metadata descriptions and a distributed search engine FFlexible data integration using mediation techniques FDynamic invocation of models to produce data on demand FInteractive data visualisation using GIS technology and VR

10 Michela Spagnuolo Istituto per la Matematica Applicata wrappers for data and programs THETIS architecture data retrieval engine search engine programs data programs

13 Michela Spagnuolo Istituto per la Matematica Applicata THETIS Demonstrator Scenarios kWaste Transport, for the simulation of pollution point sources general circulation data, concentration of effluents, transport of pollutants kTracking of Sea Structures, for the study of the dynamic of oceans oceanographic structures kNearshore and Offshore Waves, for coastal defences, coastal and offshore structures, flood prevention, etc F Calculation of the wave climate based on historical wind and wave data F Estimation of directional (2D) spectra of surface waves based on heave-pitch-roll time series

14 Michela Spagnuolo Istituto per la Matematica Applicata IMA-CNR Contribution kEmbedding 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 kIntegration 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

15 Michela Spagnuolo Istituto per la Matematica Applicata Surface modelling system: a shape-based approach data shape reconstruction enriched data enriched data shape-based model abstraction reconfiguration analysis bathymetric profiles shape-based model shape reconstruction filtering shape-based model digitalized contours constrained Delaunay TIN medial axis transform

16 Michela Spagnuolo Istituto per la Matematica Applicata Virtual Reality Computer interface technology for the interaction with real- time 3D virtual environments in a more intuitive manner Virtual Environments realistic,interactive and immersive simulations of places and scenes

17 Michela Spagnuolo Istituto per la Matematica Applicata Virtual Reality for Geodata kVR, 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 kVRML: 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
