stereoscopic three-dimensional display. This shows the GeoExpress visualization software, projecting

University of Manchester combined with curved map overlays (Google Earth, 2007). It is
proposed that using stereoscopic presentations with a large screen allows an environment
where understanding of the space is more intuitive. With a speaker and an audience these
examples show a second mode of visualization, one-way presentation and demonstration.
The important part here is that there is a presenter who can 'tell a story' to the audience.
The final mode of visualization is team interrogation, where a small group of experts
interact collaboratively with data sets to discover new patterns and understandings. Figure
11.13 shows LiDAR (light detecting and ranging) data of a detailed scan from the 'badlands'
of South Dakota, captured during fossil gathering by university palaeontologists. This was
presented for open discussion to a group of earth scientists, including geologists and seis-
mologists. They were encouraged, and able, to discuss openly contentious issues with the
