Topic: "Developing an Electronic Theater"

An example of an Etheater will be demonstrated showing the visual analysis of real and simulated earth science hyperdata for NASA research and public outreach (hurricanes, tornadic thunderstorms, lightning, pack ice flow,and so on).

About the Event

Find out how Dr. Hasler puts his Electronic Theater together: the software and hardware, the time it takes to prepare. You too can wow your customers and impress your clients with activity going on in three screens. This electronic theater demonstrates new methods for visualizing, interpreting, comparing, organizing and analyzing immense HyperImage remote sensing datasets and three-dimensional numerical model results. The data is called from many new Earth sensing satellites, HyperImage datasets, because they have such high resolution in the spectral, temporal, spatial, and dynamic range domains. The traditional numerical spreadsheet paradigm has been extended to develop a scientific visualization approach for processing HyperImage datasets and 3-D model results interactively. The advantages of extending the powerful spreadsheet style of computation to multiple sets of images and organizing image processing is demonstrated using the Interactive Image SpreadSheet (IISS).

Visanalysis of: 1) simultaneous satellite and aircraft radar images of hurricane Luis, 2) lightning detector data merged with GOES image sequences, 3) SSM/I microwave spectrum animations of daily North Polar ice pack data, and 4) synchronized manipulation of multiple 3D numerical model views; will be illustrated.

The Image SpreadSheet has also been highly successful in producing Earth science visualizations for public outreach. Many of these visualizations have been widely disseminated through the world wide web pages of the HPCC/IITA/RSD program which can be found at The 1-minute interval animations of Hurricane Luis used by Peter Jennings on ABC Nightline and the color perspective rendering of Hurricane Fran published by TIME, LIFE, Encyclopedia Britannica and Popular Science are some of the examples which will be shown.

Don't forget your business cards! We collect a business card from each attendee for a chance to win the registration fee for the Annual conference. The drawing takes place at the March meeting. The more meetings you attend, the more chances to win.
