Three Dimensional Terminal Viewer Display, Part 1 of 2, 1993

John McCarthy, Director, Research Applications Program, explains the new three-dimensional terminal viewer display. It is a virtual reality system, with weather and air-traffic graphics running in real time. The Terminal Doppler Radar information with 3D terrain and air traffic are all on one display. The first demonstration shows Denver International Airport from a point looking down from space. He shows the air traffic live view added to the traditional view, and then the landsat background gets added. Subsequently, the weather precipitation from TDWR is added. This feature hides the airport & planes. The light rain is then removed, leaving only the moderate to heavy rain on the screen. At 5:20, microburst & gust front information is added. At 5:40, only heavy precipitation is shown. These are all 2D images. At 6:23, the circle terminal control area is the new 3D image, from about 50 miles away from the airport with the same features. Points of the compass are shown on the edges.
