ILocalOp.Rank Method

Calculates the local rank between GeoDatasets.

[Visual Basic .NET]
Public Function Rank ( _
    ByVal ValueData As IGeoDataset, _
    ByVal LocalData As IGeoDataset _
) As IGeoDataset

[C#]
public IGeoDataset Rank (
    IGeoDataset ValueData,
    IGeoDataset LocalData
);

[C++]
HRESULT Rank(
  IGeoDataset* ValueData,
  IGeoDataset* LocalData
);

[C++]

Parameters
ValueData [in]

  ValueData is a parameter of type IGeoDataset*
LocalData [in]

  LocalData is a parameter of type IGeoDataset*

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

valueData	an input Raster, RasterDataset, RasterBand, or RasterDescriptor defining the position in the rank order of the specified inputs in the argument list defined by localData to derive the output value
localData	a multiband input Raster, RasterDataset, RasterBand, or RasterDescriptor defining the argument list to identify the value for the rank, defined by the first argument for each cell location

The method returns a reference to a Raster object.
