The seven color image above shows a classified image of a small
Bahia field in South Alabama. The image shows seven relative
differences in vegetation. The grower knew he had some weaker
areas in the field, but wanted to locate them more precisely in
the field. Secondly, he wanted to know if there were any spots in
the field he could not see in the field.
To the grower's
surprise the image indicated several locations in the field where
the grass was weaker compared to the rest of the field. Many of
those areas were not visible by eye.
The weaker areas
were areas where the grower fed his cows round bales. The high
traffic of the cows have negatively influenced the Bahia grass in
those areas. The knowledge he has gained with this image has
helped this grower to pay more attention to these areas to
increase the productivity of the field.
