INeighborhoodOp.FocalFlow Method

Calculates the flow of the values in the surface within each cells immediate neighborhood.

[Visual Basic .NET]
Public Function FocalFlow ( _
    ByVal geoDataset As IGeoDataset, _
    [ByRef thresholdValue As Object] _
) As IGeoDataset

[C#]
public IGeoDataset FocalFlow (
    IGeoDataset geoDataset,
    ref object thresholdValue
);

[C++]
HRESULT FocalFlow(
  IGeoDataset* geoDataset,
  Variant* thresholdValue
);

[C++]
Parameters
geoDataset [in]

  geoDataset is a parameter of type IGeoDataset*
thresholdValue [in, optional]

  thresholdValue is a parameter of type VARIANT*

Product Availability

Available with ArcGIS Engine, ArcGIS Desktop, and ArcGIS Server. Requires Spatial Analyst Extension.

Remarks

geoDataset

an input integer or floating-point grid that identifies the values of the focal or processing cell and the values of the cells in its specified neighborhood

INeighborhood::FocalFlow evaluates the eight immediate neighbors of a cell to determine flow.

[thresholdValue]

defines a value that constitutes the threshold, which must be equalled or exceeded before flow can occur

If the difference between the value at a neighboring cell location and the value of the processing cell is less than or equal to the threshold value, the output will be ‘0’ (or no flow). The data type for thresholdValue can be either integer or floating point.
