Geographic
Information System
GIS
is, simply, maps on a computer. GIS has the ability to take several
different maps and place them on top of each other to display
unique
sets of data. With GIS you could take a geology map and a map of
property boundaries and determine which properties were underlain
by limestone bedrock, and therefore had a greater chance of sinkhole
formation.GIS stores the map data in the computer. It allows
easy
access to the data and makes it easier to manipulate the data than
if it were stored on paper maps. The LCCD uses programs such
as
ARC/INFO and ARCVIEW to perform these functions.
