• One research image processing workstation with' a Number Nine Computer Corporation 
Revolution 512x32 board (512x512x32 bits) with hardware roam and zoom, and ERSC developed 
software. The board is mounted in an IBM AT that has 140 MB of hard disk space, a math 
coprocessor, a monochrome display and a Professional Graphics Display. 
• One 25 MHz 386 Compaq workstation with ERDAS image processing software and a Truevision 
AT Vista board (1024x1024x32 bits) with hardware roam and zoom. The workstation also has 
a 300 MB disk drive, 200 MB IBM 3363 optical disk drive, 5 MB RAM, a 80387 math 
coprocessor and a monochrome monitor. This workstation also functions as a GIS workstation 
with pcARC/INFO, EPPL7, and pMAP software and a 36" by 48" Calcomp digitizing tablet. 
• One 25 MHz 386 CompuAdd workstation with ERDAS image processing software and an 
Imagraph board (1024x1024x32 bits) with hardware roam and zoom. The workstation also has 
a 600 MB disk drive, 200 MB IBM 3363 optical disk drive, 5 MB RAM, a 80387 math 
coprocessor and a VGA monitor. This workstation also functions as a GIS workstation with 
pcARC/INFO and EPPL7. 
• One GIS workstation with pcARC/INFO, EPPL7 and pMAP software on a CompuAdd 386 
computer. This workstation has 120 MB of hard disk space, a 16 MHz 80386 CPU, a math 
coprocessor, a monochrome monitor, and IBM Professional Graphics Adapter and Display. 
• An IBM PS/2 Model 80 computer with a VGA color display, 70 MB hard disk, an 80386 CPU, 
a 80387 math coprocessor, 4 MB RAM, PRONET network link to the McIDAS mainframe 
computer (a meteorological satellite data processing system), and pcMcIDAS software. 
• One 16 MHz Compaq Deskpro 386 workstation with 140 MB of hard disk space, 4 MB RAM, 
an 80387 math coprocessor, and a cartridge .tape backup unit. 
• Three 9-track reel-to-reel tape drives (two 6250 bpi drives and one 1600 bpi drive). 
• a Matrix Instruments PCR digital film recorder, two Hewlett-Packard 7475A 6-pen plotters and 
a Houston Instruments DMP-40 plotter, 3 Hewlett-Packard Laserjet printers, two Tektronix 4696 
color inkjet printers, an IBM color printer, an IBM Proprinter II, and an IBM Colorjet printer. 
• an IBM PC serving as a gateway between the ERSC LAN and the CAMPUS PC network and 
an Ethernet link to the campus backbone network. Through this link we can access computers 
including the Vax computer cluster at the Madison Academic Computing Center, the San Diego 
Cray X-MP supercomputer, the National Center for Atmospheric Research (NCAR), 
ARPANET, USAN, BITNET, NSFNET and campus, national and international electronic mail. 
• Fourteen additional computers including, 2 AT-compatible computers serving as network file 
servers with 540 MB of hard disk space, 6-AT compatible computers serving as word processing 
and program editing workstations, and six additional computers for ERSC faculty and staff use. 
Over the years, ERSC researchers have developed an extensive package of computer programs for digital 
image analysis. The package includes software for the analysis of digital Landsat, SPOT, AVHRR, and 
GOES data; digitized photography; and electro-optical scanner data. Routines are available for 
geometric and radiometric image calibration, image enhancement, and image classification. Also 
available are specialized programs for the performance of such functions as the generation of full-color 
cartographic products and merger of remote sensing data with other sources of data in the various GISs 
available to ERSC researchers (e.g., pMap, ODYSSEY, EPPL7, ERDAS, and pcARC/INFO).
