Creates a raster of accumulated flow to each cell.
[Visual Basic .NET] Public Function FlowAccumulation ( _ ByVal directionRaster As IGeoDataset, _ [ByRef weightRaster As Object] _ ) As IGeoDataset
[C#] public IGeoDataset FlowAccumulation ( IGeoDataset directionRaster, ref object weightRaster );
[C++]
HRESULT FlowAccumulation(
IGeoDataset* directionRaster,
Variant* weightRaster
);
[C++] Parameters directionRaster [in]
directionRaster is a parameter of type IGeoDataset* weightRaster [in, optional]
weightRaster is a parameter of type VARIANT*
directionRaster | a raster showing direction of flow out of each cell
This can be created using the IHydrologyOp::FlowDirection method. |
[weightRaster] | the weight to be assigned to each cell
If no [weightRaster] is specified, a default weight of one will be applied to each cell. For each cell in the output, the result will be the number of cells that flow into it. The data type for the weightRaster can be any Raster object that supports IGeoDataset (e.g., Raster, Raster band, etc.). |
