The seven color classified image above shows a cotton field
in South Alabama. The grower is renting the land. The rent is
based on the total acreage in the field. The majority of the areas
in class 1 (dark brown) are ditches. However, some of these areas
are low laying areas where water prohibited sufficient plant
growth early in the season. The acreage for each class can easily
be calculated from this imagery. The grower would like to use the
image to show the owner the limited use of the field.
The picture on the top left shows one
of the ditches that runs through the field. Obviously, that area
is not productive. However, it also limits the area that can be
planted because the planter has to deal with the ditches.
The second picture was taken towards
the south and shows cotton in class 7 (dark green) areas.
The third picture was taken towards the
north and shows a big contrast from the previous picture. The
picture shows cotton plants in class 1, 2, and 3 (dark brown,
beige, and light yellow). Abundant water has limit early season
growth and in many case drowned the cotton.
