Earth Search Sciences Takes High-tech Mapping to the Farm.

Business Editors

KALISPELL, Mont.--(BUSINESS WIRE)--April 9, 2002

Earth Search Sciences, Inc. (OTCBB:EDIS.OB) announced today that it has been awarded a contract to collect hyperspectral data from its leading airborne platform for the Remote Sensing Technologies Center (RSTC) at Mississippi State University.

The extensive work to develop and validate agriculture-related remote sensing technologies -- an area of demonstrated success for Earth Search Sciences -- will generate more than $200,000 in revenue. The RSTC project will require Earth Search to collect Probe 1 hyperspectral data over a number of research sites in Mississippi beginning in early May 2002. RSTC will use this data over these highly characterized sites to develop and validate agriculture-related remote sensing technologies.

The drive to refine precision farming provides an opportunity to demonstrate how hyperspectral remote sensing technology can be used effectively and efficiently to identify crop conditions, improve decision-making, and reduce agricultural chemical usage while improving farm profitability.

"The RSTC is focusing on next-generation technologies for agriculture and natural resource management," said David Shaw, RSTC Director. "The hyperspectral data generated from this program with Earth Search Sciences will be an essential part of our research efforts for 2002 and 2003."

"This project represents an evolution in our relationship with the Remote Sensing Technologies Center at Mississippi State. What began as a small collection to prove our concept and our team has grown into a relationship that generates significant revenue as decision-makers depend on high technology to advance agricultural practices," said Larry Vance, ESSI chairman. "Importantly for our company, in both quality and extent, this work is typical of the opportunities presented us in agriculture in the present and near-future."

Mississippi State University established the RSTC to focus on developing applications of remote sensing technologies in agriculture, forestry, transportation and environmental assessment. A primary sponsor for the RSTC is the NASA Stennis Space Center's Earth Sciences Applications Directorate. Additional information on Mississippi State University and RSTC can be found at www.rstc.msstate.edu. The overall goal of the research program of the RSTC is to produce a robust research process that defines the role of the land-grant university in applying remote sensing technologies to solve problems that affect our stakeholders. Earth Search Sciences is a world leader in hyperspectral remote sensing. ESSI's first-of-its-kind instrument, Probe 1, delivers data that registers a "spectral signature" of the object being scanned. Each object in the environment gives off a unique spectral "signature" that can be recognized by ESSI's instrument and associated processing software.

Earth Search Sciences has carried out work for such important clients and partners as NASA, Boeing, BP Amoco, Barrick Gold Corporation, the Dian Fossey Gorilla Fund International, Lockheed Martin, SAIC, the U.S. departments of Energy, Agriculture, Defense, Interior and the EPA.
