maintenance of faunal and floral diversity within the town.

or aesthetic resources.

Composite
Result of Critical Lands Analysis - result of overlaying the four
previous resource themes. The resource themes were reclassified into a
presence/absence classification and added together. The value of
each pixel was recomputed using a 3-pixel average filter to take into account
the quality of surrounding landscape. Areas that are already protected
(i.e. DEM management areas and open water) were then removed from the composite.
The resulting map shows the areas that are most critical for protection
for Hopkinton, RI. We used a statistical method to identify categories of importance for conservation.
Orthophotography
- digital orthophotography in which distortions associated with traditional
aerial photography have been removed. This is a useful map because it allows
users to easily cross-reference the location of critical resource regions
on the landscape.
