Overview

Introduction Project GDI-3D Sensor Web & 3D Summary & Outlook Video Demo


Introduction

Search, management and visualization of 2D spatial data (raster & vector)

Is this enough?

New applications are emerging:

processing and analyzing

mobile applications – LBS

3D applications

Real-time data available

SDIs today

Approach to integrate sensor data into 3D-SDI

Based on open standards of the OGC

Sensor Web Enablement (SWE)

Different use-cases to show potential

3D-SDI Project GDI-3D


Project GDI-3D

Finding best practices for 3D data exchange, data preparation and user interaction

3D-SDI based on relevant OGC services like WFS, WMS, CS-W, WCS

Web 3D Service (W3DS) > serving 3D scenes within a special 3D viewer

Test case: city of Heidelberg (www.gdi-3d.de)

German-wide 3D-SDI (www.osm-3d.org)

Public Information


New OGC initiatives like SWE bridge open gaps in Spatial Data Infrastructures

Basis for more sophisticated & valuable applications within SDIs

Standardized sensor information & 3D More spatial information (3rd Dim) for further

investigations 3D visualization much more impressive

Powerful Tools

Summary

Future Work


Processing of the sensor data >> WPS Interpolation of point information to 3D-surfaces Calculation of spatial densities

Integration of further real time sensor data 3D-simulations Context aware maps / 3D scenes Tracking
