LANDSCAPE ELEMENT VISIBILITY AS
A FUNCTION OF ENVIRONMENT
NORTHEAST
STUDY AREA I
Binary decision of hills/
mountains or valleys/low-
lands; little variation;
changes are generally
subtle.
Generally uniform in
appearance; little change
noticeable; tends to
pervade entire area; a
hinderance in identifying
other landscape elements.
Irregular shapes in
numerous sizes but most
are small; fields are
non-uniform (mottled) in
appearance and lack
clarity/preciseness;
fragmentation adds com-
plexity & reduces
identification confidence.
Scattered, less predictable
locations; difficult to
confidently detect owing
to vegetation cover; HV
very important in veri-
fying presence.
Roads, railroads masked
by vegetation; not easily
discerned; power lines
are identifiable as a
result of contrast pro-
duced by removing forest
cover from line path.
MIDWEST/WEST
STUDY AREA II
Number of contrasts; transi-
tions of slope; variety of
drainage networks, type and
frequency of water bodies.
Great diversity in amount
of cover, patterns, loca-
tion, frequency and
distribution (partially a
function of range in climate,
soils, and moisture).
Rectangular fields in
continuous pattern or large
areas of rangeland; field |
appearance normally uniform
and borders defineable.
Regular or periodic in
location, distinctive
signatures easily dis- lu
cerned; borders with
surrounding area are |
clear. |
Roads, railroads readily IM
visible, power lines |
detectable by return from
poles at times.
