Question

Quizplus · Accepted Answer

Training areas are representative samples of different thematic classes selected by the image analyst based on their knowledge of the study area and the imagery being used. The computer may assist in identifying potential areas, but the final selection is made by the image analyst. Spectral clusters may be used to identify potential training areas, but they are not the training areas themselves.
