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

Introduction
Christian Mayer, GeoVIZ Workshop 2009, Hamburg, Germany 4
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
10. April 2023 Christian Mayer, GeoVIZ Workshop 2009, Hamburg, Germany 5
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)

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
