ESSI Yellowstone Project Achieves Firsts in Environmental Research and Hyperspectral Remote Sensing.

MCCALL, Idaho--(BUSINESS WIRE)--Oct. 27, 1999--

Earth Search Sciences, Inc., (OTCBB:EDIS) today announced that the company has delivered what it believes to be the world's first successful commercial collection of one meter hyperspectral remote sensing data in Yellowstone National Park this summer, giving scientists significantly greater mapping precision than ever before.

"The high spatial resolution of this newest Earth Search data literally looks like an aerial photograph with full scientific detail," said Dr. Bob Crabtree, research director for Yellowstone Ecosystem Studies. "With the pixels at one meter wide and each containing up to 128 bands of information, we are now looking at new information for the first time. The higher resolution information makes it difficult for anything -- whether it's pollution, precious metals, specific plant species, etc. -- to hide from the Probe-1."

"The conventional wisdom was that the collection of one meter data couldn't be done, but we did it anyway," said Larry Vance, ESSI founder and chairman.

Earth Search was able to deliver raw data to scientists in near real-time: meaning scientists were able to view raw data and initial images in less than one hour. Furthermore, scientists were able to view processed data the same day. ESSI's speed of processed information delivery is an important advancement since other systems take as long as six to eight months to generate processed data. Earth Search was able to deliver the data in less than one hour using a hybrid software system the company built with Micron computer equipment. Crabtree says the near real-time turnaround marks a first for his research team.

The mission was accomplished with the help of a retrofitted helicopter and an experimental heliocourier aircraft supplied by Boeing's Phantom-Works (www.boeing.com/defense-space/military/phantom/phantom.htm) which partnered with Earth Search Sciences on the mission. Phantom Works also provided its highly accurate C-MIGITS II global positioning system for use in the mission.

Earth Search hopes to make the images collected during the project available to the public on the Internet through Earth Search's wholly owned subsidiary, TerraNet, Inc., and its www.general-imaging.com web site. Currently under development, TerraNet is a direct-channel, multi-media imagery Internet supermarket offering detailed, objective and synoptic earth resource mapping products. ESSI has completed the initial beta tests for general-imaging.com and expects to make it available to the public in 1999.

Earth Search's Probe-1 advanced hyperspectral imaging instrument creates ultra high-resolution images of the earth's surface. Analysis of these images can determine the presence of target minerals and hydrocarbons in geologic formations.
