Environmental application of aerial reconnaissance to search for open dumps
Three approaches to using aerial photography are evaluated for searching for open dumps in the state of Indiana. Photography with hand-held cameras from a small airplane proved more effective and flexible than either photo-interpretation of existing air photos or subcontracting to a federal agency for new aerial photography. The rationale for our choice of aerial reconnaissance, other uses of low-level aerial surveillance, the utility of small-format camera aerial photography for environmental analysis, and methods used for locating open dumps are discussed.

vii EXECUTIVE SUMMARY ix CHAPTER
35-MM QUADRICAMERA
A QUADRICAMERA SYSTEM FOR AERIAL NON-METRIC PHOTOGRAPHY WAS DESIGNED AROUND THE ROBOT 35-MM CAMERA SYSTEM. THE QUADRICAMERA ALLOWS BOTH MULTIBAND AND MULTIEMULSION TECHNIQUES AND WAS DESIGNED FOR MULTISPECTRAL INVENTORY, RECONAISSANCE AND NON-PHOTOGRAMMETRIC STUDIES OF SHORELINES, MARSHLANDS, ESTUARIES AND HARBORS. STANDARD PHOTOGRAPHIC EQUIPMENT ALLOWS FOR INEXPENSIVE CONSTRUCTION, AND THE 35-MM FILM FORMAT ALLOWS FOR INEXPENSIVE OPERATION. COMPACT DESIGN ALLOWS FOR USE FROM LIGHT AIRCARFT, ALSO REDUCING OPERATION COSTS. THE ROBOT QUADRICAMERA SYSTEM IS COMPLETELY MECHANICAL IN OPERATION AND REQUIRES NO ELECTRIC POWER SUPPLY. INTERNAL SPRING-DRIVE MOTORS WITHIN THE CAMERA PROVIDE FOR SHUTTER COCKING AND FILM ADVANCE, AND 50 EXPOSURES ARE POSSIBLE EFORE REWINDING. A SPECIAL MECHANICAL SHUTTER-RELEASE SYSTEM, DESIGNED FOR THE QUADRICAMERA, ALLOWS SIMULTANEOUS TRIPPING OF ALL FOUR CAMERAS. /AUTHOR/
