Visual Comparison of Sheds

Original vs. New Local Shed assignment

  • The first shed shows initial pits which are removed in the first step of pit removal (This doesn’t exist in the original program)
  • The next two are the local sheds (shedno) after amalgamating the small ones
  • Black dots are pit centres (final centres for Orig, local centres for New)
  • White outlines are Fill Pour Points for the local watersheds

Original vs. New Fill Shed assignment

  • These are the fill sheds, which reflect how sheds combined during the third pit removal process
  • Black dots are pit centres, white dots are Fill Pour Points for the final watersheds
  • Shapes should be identical to pond filling, just the numbers may be different

Differences

  • Each figure represents a different Pond measurement plotted by watershed
  • Blue represents original values, pink new values. If they are identical, pink is hidden by blue

Differences

  • Each figure represents a different Fill measurement plotted by watershed
  • Blue represents original values, pink new values. If they are identical, pink is hidden by blue

Inverted DEM

  • Black dots indicate pits, or, as this is inverted, peaks
  • White dots indicate flow points

Compare values

  • Each figure reprsents a watershed measurement
