The UWCL has an extensive array of production, research and instructional equipment, including both 
traditional cartographic equipment (copy cameras, processor, platemakers, contact workstations, enlarging 
projector, densitometer and punch registry system) and computer-based equipment (microcomputers with 
color graphics monitors, digitizing tablets, image scanner, pen plotter, inkjet plotter, dot matrix and laser 
printers, and an extensive software library). 
The Arthur H. Robinson Map Library serves the university and state as a major lending library devoted 
solely to maps and airphotos. The collection includes 242,000 maps (including more than 50,000 USGS 
quadrangle maps), 182,600 aerial photographs, and 2,470 airphoto mosaic indexes. 
Environmental Remote Sensing Center 
The IES Environmental Remote Sensing Center (ERSC) is one of seven research centers administered 
by IES. ERSC’s mission is to provide a physical and intellectual focus for interdisciplinary research on 
the development and application of remote sensing in natural resource management and environmental 
monitoring. The research agenda for ERSC is broadly based-dealing with the application of remote 
sensing across the local to global continuum, and involving the merger and synthesis of remotely sensed 
data with other sources of land-related information in a GIS context. 
ERSC is one of the oldest and largest, university remote sensing research centers in the U.S. ERSC 
researchers deal with diverse research topics (see previous list). The activities of ERSC are closely 
coupled with the Environmental Monitoring graduate program. That is, certain courses are taught using 
ERSC facilities, and the thesis research of virtually every student in this program is either funded 
through ERSC or involves the use of ERSC equipment. 
ERSC maintains a variety of equipment for remote sensing data acquisition and analysis. Major 
equipment items include equipment for data acquisition (35 mm, 70 mm, and 240 mm camera systems 
for aerial photography, a Texas Instruments RS-18A thermal scanner with all-digital recording system 
and an on-board microprocessor-based color display and processing system, a Barnes PRT-5 radiometer 
and Barnes Modular Multiband Radiometer for multispectral field measurement in spectral bands 
matched to the Thematic Mapper), equipment for data capture from images (digital spot microdensi- 
tometer, Optronics P-1700 Photomation scanning/writing microdensitometer for scanning of either 
black-and-white or color film and digital recording on a tape drive, and a video digitizer), and equipment 
for visual image analysis (pocket, mirror, scanning and zoom stereoscopes with light tables, Zoom 
Transfer Scope™, color additive viewer, and photographic darkroom equipment). 
In addition, ERSC maintains an extensive set of resources for digital image processing, as outlined below. 
• Nine image processing workstations in an instructional laboratory. Each workstation consists of 
a CompuAdd 25 MHz 386 computer, with 480 to 600 MB of hard disk space, 16 MB RAM, a 
math coprocessor, a VGA color display, an Imagraph display board (1024 x 1024 x 32 bits) and 
high resolution monitor, and 2 diskette drives. All workstations maintain a set of ERSC written 
image processing software, as well as a number of commercially available packages including 
ERDAS and pcARC/INFO software. Two 36" x 48" Calcomp digitizing tables are also available 
in the laboratory’. 
• One array processor workstation v/ith an AT-compatible computer with 4 Transputer boards 
(16 CPUs). This workstation allows investigations into parallel processing algorithms. • 
• One research image processing workstation based on a Gould DeAnza FD5000 image processing 
system, with a 512 by 512 by 28-bit image memory, hardware roam and zoom, ERSC developed 
software and a color monitor with 512 by 512 display resolution. This system is driven by an 
IBM AT with over 100 MB of disk space, a math coprocessor, a monochrome display and a 
Professional Graphics Display.
