flow direction compared to D8.
4.3 ASTER Data for Swamp Area Detection
By introducing another state of water movement such as stagnant and sink, a new
application can easily be created through D16 algorithm in which D8 cannot
produce. It is the automatic detection of swamp area that was really needed, for
example, large-scale agriculture activity and estate plantation companies for their
