Introduction
• We use GIS to – process environmental data to trigger decisions –by decision makers.– to derive 2D maps from our data for the web or print to communicate.– to derive volatile 3D visualisations using GIS or other tools – to
communicate.
• Things get tricky– When the decision makers have to interact with the data.– Decision makers aren‘t GIS ninjas – and don‘t carebother to read the manual.– Volatile 3D images on 3D Screens like Geo Walls, Visio Labs etc. don‘t last for
later reference.
• Duh.

Skills + Tools + Standards:The whole is larger than its parts
• GFZ Section 1.1 is successfully operating a 3D printer - mostly for rapid prototyping
• The Centre for GeoInformation Technology (CeGIT) is involved in R&D projects involving GIS and complex data:– TRIDEC-Project: Quality checking for „2D+Time“ data stacks.– Upcoming projects: Visualizion of geological bodies in 3D.
• Common technological standards allow Section 1.1 and CeGIT to share their ressources.

Model vs. Printout of a Tsunami Simulation (Tohoku 2011)
Printing time: 11 hours

THAT is a Tsunami ?
• It‘s a space-time cube (STC) of a tsunami.
• A STC is a „stack of 2D maps“.• The maps show the same
phenomenon at consecutive points in time.
• The „paper“ is removed, „ink“ stays.

The road ahead
• Complex 3D bodies: Achieved
• Multicolor 3D bodies: Pending
• 2.5D Surfaces (Elevation models): In the works
• Hardening of the workflow: Ongoing
• Mash-Up of different information layers in one print: 2013
Next Goal: Long Night of Science 2013
