 The method adopted to filter the elevation map and rectify it is
 based on the paper titled "Software Tools to Extract Structure from Digital
 Elevation Data for Geographic Information System Analysis" by S.K. Jenson

 The flow direction map can be encoded in either ANSWERS (Beasley et.al,
 1982) or AGNPS (Young et.al, 1985) form, so that it can be readily used as
 input to these hydrologic models. The resulting depressionless elevation
 layer can further be manipulated for deriving slopes and other attributes
 required by the hydrologic models.
