In feature extraction, at the end of the process where you can specify to output segments of the classes, any segments that are classified to the same class will get merged together into the same class. It was assumed that a user would want adjacent polygons that are the same class to be considered one class. Currently there is no way to change this behavior. You can export the raw segments prior to classification, but these would just be the result of segment-merge-threshold-attribute calculation. The segments would not be assigned to the classes yet. Would this be useful?
