Automated Delineation of Wetlands in Photographic Remote Sensing

Abstract

Precision automated photometric mapping of wetlands in Calvert County, Maryland has been achieved in an operational system as the result of a program including aerial color film (both true color and false color infrared) calibration and control. Although the system was operated over this area, it may be adapted to other areas. The recognition appears to be most accurately achieved by microdensitometric analysis of the true color transparency in a narrow band centered in the red (0.633 millimicrons), on 3000-foot altitude imagery. A computer generated map is obtained.
