Remote-Sensing Procedures for Detecting and Monitoring Various Activities Regulated by the Mobile District

摘要

The objective of this study was to develop procedures for use by the U. S. Army Engineer District, Mobile, to detect and monitor activities requiring a Corps of Engineers permit pursuant to Section 404 of the Federal Water Pollution Control Act Amendments of 1972, Section 10 of the River and Harbor Act of 1899, and Section 103 of the Marine Protection, Research, and Sanctuaries Act of 1972. The detection and monitoring procedures developed in this study included three methods of acquiring remotely sensed data: satellite- and aircraft-borne digital scanner methods and airborne photographic methods. The two digital scanner systems investigated for the study were the Landsat Multispectral Scanner System and the National Aeronautics and Space Administration Modular Multispectral Scanner. The equipment and procedures used in these systems, which obtain the type of information required by the Regulatory Functions Branch, Mobile District, are described. Aerial photographic systems are described, and examples of several applications of detection and monitoring procedures involving wetlands, waterbodies, and structures are given. A summary of available remote-sensing imagery from Federal and State agencies is given.
