✦ Synopsis

Viewing terrain data from various remote sensors in three dimensions has proven to be a valuable tool for scientists in understanding a variety of problems. A technique is presented for using image pyramids in such visualization of large terrain data sets, providing up to two orders of magnitude performance enhancement over simpler techniques, while at the same time eliminating false high-frequency information, which causes animations to sparkle.

'Actually, the terrain-rendering technique is useful wherever relationships between any two types of data are sought. "Elevation" here could refer not only to terrain elevation, hut any number of measurable quantities, such as atmospheric pressure or material density, and likewise the "image" data could be any related gridded data viewable as an image.
