| GRASS GIS software was developed in response to the need for improved
analysis of landscape “trade offs” in managing government lands and the
emerging potential of computer-based land analysis tools. During the last
decades of the 20th century, government land managers in the U.S. (and
across the world) faced increasing requirements from legislation and stakeholder
groups to examine and evaluate alternative actions. To fulfill these new
requirements, land managers needed new tools.
During this same era, computational capabilities wondrously improved.
Tasks requiring days and months with paper and acetate overlays could be
accomplished with this newly emerging geographic information technology
within minutes. But even in the mid-1980s, GIS technology involved significant
capital investment. Managers wanted to see results before they spent their
limited funds on new technologies.
The U.S. Army Construction Engineering Research Laboratory (CERL) in
Champaign, Illinois has the mission of developing and infusing new technologies
for managing U.S. Department of Defense installations. These installations
include millions of acres of lands needed for military training and testing.
Other uses included wildlife management, hunting and fishing and forestry,
grazing and agricultural production. Other priorities were added through legislation
– such as protecting endangered species and habitats, protecting cultural
sites, and limiting the on and off-post impacts of noise, ordnance, contaminants
and sediments. |
