    Description

    Four techniques for inventorying manmade impacts along roadway corridors were devised and compared. Ground surveillance and ground photography techniques recorded impacts within the corridor visible from the road. Techniques on large- and small-scale aerial photography recorded impacts within a more complete corridor that included areas screened from the road by vegetation. Techniques were compared on the basis of type and quality of data obtained, types of maps produced, area covered, and relative cost and time requirements.
