IInterpolationOp2.Krige Method

Interpolates using kriging.

[Visual Basic .NET]
Public Function Krige ( _
    ByVal geoData As IGeoDataset, _
    ByVal semiVariogramType As esriGeoAnalysisSemiVariogramEnum, _
    ByVal radius As IRasterRadius, _
    ByVal outSemiVariance As Boolean, _
    [ByRef barrier As Object] _
) As IGeoDataset

[C#]
public IGeoDataset Krige (
    IGeoDataset geoData,
    esriGeoAnalysisSemiVariogramEnum semiVariogramType,
    IRasterRadius radius,
    bool outSemiVariance,
    ref object barrier
);

[C#]

Optional Values

barrier To indicate that this parameter is undefined, first define a variable object Missing = Type.Missing; then pass this in as ref Missing.

[C++]
HRESULT Krige(
  IGeoDataset* geoData,
  esriGeoAnalysisSemiVariogramEnum semiVariogramType,
  IRasterRadius* radius,
  VARIANT_BOOL outSemiVariance,
  VARIANT* barrier,
  IGeoDataset** interpolatedRaster
);

[C++]

Parameters

geoData [in]

geoData is a parameter of type IGeoDataset

semiVariogramType [in]

semiVariogramType is a parameter of type esriGeoAnalysisSemiVariogramEnum

radius [in]

radius is a parameter of type IRasterRadius

outSemiVariance [in] outSemiVariance is a parameter of type VARIANT_BOOL barrier [optional] barrier is a parameter of type VARIANT

To indicate this parameter is undefined pass a reference to a VARIANT with type VT_ERROR and scode value of DISP_E_PARAMNOTFOUND.

interpolatedRaster [out, retval]

interpolatedRaster is a parameter of type IGeoDataset

Available with ArcGIS Engine, ArcGIS Desktop, and ArcGIS Server.

Remarks

geoData	an input point featureclass containing the points with z values to be interpolated onto a surface Raster
semiVariogramType	an esriGeoAnalysisSemivariogramEnum specifying the type of mathematical function used to model the semivariance The types are: esriGeoAnalysisCircularSemivariogram circular semivariogram model esriGeoAnalysisExponentialSemivariogram exponential semivariogram model esriGeoAnalysisGaussianSemivariogram Gaussian or normal distribution semivariogram model esriGeoAnalysisLinearSemivariogram linear semivariogram model with a sill esriGeoAnalysisNoneSemivariogram no model is fit esriGeoAnalysisSphericalSemivariogram spherical semivariogram model This is a commonly used function. esriGeoAnalysisUniversal1Semivariogram Universal Kriging with linear drift The GRAPH and BOTH options are not available with the UNIVERSAL1 method.
radius	an IRasterRadius indicating the search radius for the input points The radius distance is specified in map units within which all input sample points will be used to perform interpolation. A commonly used radius is five times the cell size of the output Raster. The object will set and use whatever you set last in your VB script. For example, `set pRad.SetFixed 207.1 set pRad.SetVariable 12` will use the args ... ,SAMPLE,12, .... `set pRad.SetVariable 12 set pRad.SetFixed 207.1` will use the args ... ,RADIUS,207.1, ....
[outSemiVariance]	if True an optional output Raster will be created containing predicted semivariance values for each mesh point in output interpolation surface If the GRAPH option is specified, an {output_variance} grid will not be created.
[barrier]	a coverage or shapefile containing the arcs for the barrier information used for limiting the line search for input sample points
