Whether helping determine water quality
in an area
or assisting city managers with zoning
laws, newly
updated software recently released
by the Center for
Applied Geographic and Spatial Research
(CAGSR)
at Baylor University can get the
job done. "We put the
software on our server (Monday) at
noon and have
already seen record numbers of downloads
and hits to
our web page," said Steve Clamons,
research scientist
with CAGSR.
This major update of the GRASS Geographic
Information System (GIS) software
package is the first
update of its kind in nearly a decade.
GRASS, which
stands for Geographic Resource Analysis
and Support
System, is a public domain GIS used
for data
management, image processing, graphics
production,
spatial modeling and visualization
of any type of
spatial data. Originally written
by the U.S. Army
Construction Engineering Research
Laboratories
(USA-CERL), GRASS is currently used
by an
estimated 30,000 people in academic
and commercial
settings around the world, as well
as many
governmental agencies, like NASA
and the National
Oceanic Atmospheric Administration
(NOAA). The
web site currently receives more
than 3,000 hits daily;
that number is expected to double.
One major undertaking of CAGSR is
using GRASS
to assist in water resources research
projects. Clamons
said this research can help develop
policies for better
water management. Other CAGSR staff
involved with
the GIS at Baylor include Bruce Byars,
research
scientist, and Dr. G.W. Willis, director
of the center. In
addition to CAGSR's staff, cooperators
at the
University of Hannover in Germany,
University of
illinois and USA-CERL also contributed
to the
software release. By a cooperative
agreement with
USA-CERL, the headquarters for GRASS
support,
research and development was transferred
to Baylor in
1997. In addition to upkeep of the
GRASS GIS,
CAGSR also performs research projects
and is
responsible for GIS education across
the Baylor
campus.
