Geographic Information Systems
Computer Laboratory
The
Geographic Information Systems (GIS) Lab provides access to GIS technology.
This technology is comprised of software used to store, analyze and display
information and hardware such as computers and peripheral devices. The
lab is available to users of Geographic Information Systems as a tool
for water quality research and analysis. Users can create data bases of
spatial information and use that information to design maps and explore
spatial relationships within research projects. Some projects in the GIS
Lab include:
- Ohio River Basin Stream Models
- Global Climate Change Impacts
- Isotopic Tracers
- Watershed Models
- Land use and Water Quality Relationships
Featuring
Hardware: The hardware is network of high performance graphic computer workstations. The UNIX server and 3 UNIX workstations are networked to an NT server and 4 NT workstations. In addition to the workstation and server hard drives, there are peripheral devices for storage (zip drives, CD-Recorder, DVD-Recorder) and an HP Plotter for large format printing with Tektronix printer for smaller jobs. The Digitizing Light table is attached to a UNIX workstation for data input to Arc Info GIS software.
GIS Software: Internet access, GIS software (Arc Info, Arc View, ERDAS Imagine, Idrisi), Oracle
Notes: UNIX Server (SGI Origin 2000)- this UNIX server is ideal for data-intensive tasks and analytical computing. (Supports Web serving, intensive scientific computation.)
UNIX Workstation (SGI Octane): This workstation that provides processing power and visualization needed for GIS applications
SGI NT Workstations (320 and 540): High-performance visual workstations with the familiarity of the Intel processor.
Large and small print output devices: HP Plotter and Tektronix Printer
Storage Devices:
Iomega Zip Drives (100 MB)
CD-Rom Recorder (700 MB)
DVD Recorder (2 GIG storage)
Digitizing Light Table: This device is used for converting large maps into geographic information systems.
