1974, Enslin and Sullivan produced maps of 
the Pointe Monillee Marsh, Michigan, from 
medium-scale fcir. 
By 1975, U.S.G.S. was mapping wetlands at 
a scale of 1:24,000 using seasonal fcir as 
reported by Carter and Stewart. By 1979, U. 
S.G.S. produced wetland vegetation maps, 
7.5 quad sheets of the Tennessee Valley area 
on which six vegetative classes and twelve 
sub-vegetative classes were shown. Also in 
1979, Howland completed the wetland mapping 
of the Shelbourne Pond, Vermont area, in 
which he tested three types of imagery, con 
ventional color, fcir, and color-enhanced 
multi-band imagery. He concluded that the 
fcir imagery was best after delineating and 
classifying sixteen separate and distinct 
wetland types 
The modern methods of field ecology sur 
vey are often difficult, time consuming and 
too clostly to apply to wetland delineation 
and classification. In particularly fragile 
ecosystems, comprehensive biological field 
studies can cause far more physical damage 
than would an appropriate ground control 
program in a small portion of the area and 
subsequent imagery analysis.
