The GIS facility within the Department of Biological Sciences at
UA maintains a variety of hardware, peripherals, and software for
use by students interested in GIS analyses in their research. The
primary computer platform, a DELL dimension 4100, has installed
the following: ArcGis 8.0 (including all needed modeling and spatial
analysis modules), ArcView 3.2, BASINS, Adobe Illustrator 9.0, and
Photoshop Elements for use analyzing data and product production.
A second DELL computer running NT with ArcView 3.2 is also available
as needed. Other available peripherals include: CD writers, Sprintscan
35 and Sprintscan 4000 slide scanners, HP flat-bed scanners, HP
4500N color printer and Polaroid 6000 slide recorder, Digital video
camera and video-capture system, as well as a VHS tape recorder
and 21” monitor. The lab also has GPS capability with a Trimble
GeoExplorer II w/ antenna.
From previous research projects we have developed a substantial
spatial database library. The major databases include 1) digital
elevation data for all of Alabama; 2) USGS National Land Cover Data
for Alabama and adjoining states; 3) hydrography for Alabama (1:24,000);
4) digital topographic maps for Alabama (at various scales); 5)
drainage basin delineations and DEMs for many watersheds studied
in earlier research efforts; 5) aerial photos of selected areas.
Recent research projects have involved hydrological studies at
the Talledega Wetland (Water Budget, E-T analyses), relationship
between land cover and Mercury concentrations in fish in Mobile
River and Regional comparisons of fish biodiversity.
