IExtractionOp.Sample Method

Extracts the cells of a raster based on a sample.

[Visual Basic .NET]
Public Function Sample ( _
    ByVal locationDataset As IGeoDataset, _
    ByVal collectionOfRasters As IGeoDataset, _
    ByVal resampleType As esriGeoAnalysisResampleEnum _
) As ITable

[C#]
public ITable Sample (
    IGeoDataset locationDataset,
    IGeoDataset collectionOfRasters,
    esriGeoAnalysisResampleEnum resampleType
);

[C++]
HRESULT Sample(
  IGeoDataset* locationDataset,
  IGeoDataset* collectionOfRasters,
  esriGeoAnalysisResampleEnum resampleType,
  ITable** outTable
);

[C++]

Parameters
locationDataset [in]

  locationDataset is a parameter of type IGeoDataset
collectionOfRasters [in]

  collectionOfRasters is a parameter of type IGeoDataset
resampleType [in]

  resampleType is a parameter of type esriGeoAnalysisResampleEnum
outTable [out, retval]

  outTable is a parameter of type ITable

Product Availability

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

Remarks

locationDataset

an input Raster, RasterDataset, RasterBand, RasterDescriptor, FeatureClass or FeatureClassDescriptor which defines the cells to sample

Cells in the locationDataSet with valid values will be sampled.

collectionOfRasters

a multiband input Raster, RasterDataset, RasterBand, or RasterDescriptor whose values will be sampled based upon the locationDataset

resampleType

an esriGeoAnalysisResampleEnum specifing the resampling algorithm to be used when sampling a Raster

resample enumeration types are,

esriGeoAnalysisBilinear - bilinear interpolation

esriGeoAnalysisCubic - cubic convolution

esriGeoAnalysisNearest - nearest neighbor assignment
