Interpretive Summary: This paper describes a true digital imaging system assembled for the U.S. Environmental Protection Agency. The system is primarily comprised of three black-and-white digital cameras, a computer and a global positioning system. The system obtains real-time color-infrared composite imagery having 1024 by 1024 pixels resolution and can store approximately 500 color rcomposite images. Digital imagery acquired with the system in testing trials has shown it has potential use for remote sensing applications.

Technical Abstract: This paper describes a true digital imaging system assembled for the U. S. Environmental Protection Agency (EPA). The system components consist of two 35.6-cm monitors, three black-and-white (B&W) noninterlaced digital charge coupled device (CCD) cameras, a computer, a versa module europa (VME) enclosure, and a global positioning system (GPS). The cameras are visible/ near-infrared (NIR) light sensitive (0.4 - 1.0 um waveband) that have built-in analog/digital (A/D) converter and are equipped with sensors having an array of 1320 (H) by 1035 (v) light sensitive pixels. The cameras are also equipped with narrowband interference filters. The computer is a pentium (100 MHZ) system that is interphased with the VME enclosure which contain three image grabbing boards that obtain 1024 by 1024 pixels resolution imagery. The computer can store approximately 500 color composite images. The GPS data is simultaneously acquired with the imagery yand stored into a separate computer text file. Digital imagery acquired with the system in testing trials has shown it has potential use for remote sensing applications. Imagery obtained with the system is presented.
