Spatial Analyst Extension
All of the analyses in the third section
of this class require an ArcGIS
extension. An extension is just an additional piece of
software that can be added to ArcGIS for more funcionality. The Spatial Analyst extension is the
ArcGIS extension used for raster processing, such as landcover and
imperviousness analyses.
Spatial Analyst requires an additional license which you can obtain
from ESRI.
Maine state agency users will not need to do this, as licenses are
already procured.
Once the license is installed, the Spatial Analyst extension can be
enabled by using the "Extensions" dialog in the "Tools" menu in any
ArcGIS application, such as ArcMap:
Tools menu - Extensions will
bring up the extensions licensing dialog. A check-mark here
indicates you have a license checked out.
IMPORTANT - you need to
get into the habit of turning "off" the extension after you have used
it. Otherwise, it will remain "on" every time you use ArcGIS
(even though you may not be using Spatial Analyst), and you will be
wasting a license. There are a limited number of extension
licenses for Maine state users. Turn it "off" as soon as you're
done using it.
