Riggins U. S. Army Construction Engineering Research Laboratory, Champaign, Illinois <p>Computer-aided environmental impact analysis can be efficient and economical. New regulations from the Council for Environmental Quality have established an operating environment in which computers can be used even more effectively. This paper describes the environmental impact analysis process, examines areas of potential computerization of this process, and describes the current status of computer-aided environmental impact analysis.</p><p>Computer-aided procedures can be applied in almost all steps of environmental impact analysis. Three types of information can be systemized: management information, technical information, and quantitative output from analytic models. Existing systems are mostly oriented toward technical information, but current development activities are incorporating analytic models. Maximum efficiency can be achieved if the total process is developed to take advantage of emerging computer technology.</p> L. B.
