# Grid Shrink/Expand

V.Wichmann & O.Conrad (c) 2011
Regions with valid data in the input grid can be shrinked or expanded by a certain amount (radius). Shrinking just sets the border of regions with valid data to NoData, expanding sets NoData cells along the border of regions with valid data to a new valid value, computed by the method selected (min, max, mean, majority).
