IReclassOp.Slice Method

Slices a range of values of the input cells by zones of equal area or equal interval.

[Visual Basic .NET]
Public Function Slice ( _
    ByVal GeoDataset As IGeoDataset, _
    ByVal sliceType As esriGeoAnalysisSliceEnum, _
    ByVal zoneCount As Integer, _
    [ByRef baseZone As Object] _
) As IGeoDataset

[C#]
public IGeoDataset Slice (
    IGeoDataset GeoDataset,
    esriGeoAnalysisSliceEnum sliceType,
    int zoneCount,
    ref object baseZone
);

[C++]
HRESULT Slice(
  IGeoDataset* GeoDataset,
  esriGeoAnalysisSliceEnum sliceType,
  long zoneCount,
  Variant* baseZone
);

[C++]
Parameters
GeoDataset [in]

  GeoDataset is a parameter of type IGeoDataset*
sliceType [in]

  sliceType is a parameter of type esriGeoAnalysisSliceEnum
zoneCount [in]

  zoneCount is a parameter of type long
baseZone [in, optional]

  baseZone is a parameter of type VARIANT*

Product Availability

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

Remarks

geoDataset

an input Raster, RasterDataset, RasterBand, or RasterDescriptor

The values contained in this Raster will be the values that are sliced.

sliceType

An esriGeoAnalysisSliceEnum specifying the manner in which to slice the values in the input geoDataset.

EsriGeoAnalysisSliceEqualArea -  EqualArea specifies that the input values will be divided into the number of zones specified by zoneCount with each zone having a similar number of cells - each zone represents a similar amount of area.

EsriGeoAnalysisSliceEqualInterval - The EqualInterval slice determines the range of the input values and divides the range into zoneCount. Each zone on the sliced output raster has the potential of having input cell values that have the same range from the extremes.

EsriGeoAnalysisSliceNaturalBreaks -  The NaturalNeighbor slice specifies that the classes will be based on natural groupings inherent in the data. Break points are identified by picking the class breaks that best group similar values and maximize the differences between classes. The cell values are divided into classes whose boundaries are set where there are relatively big jumps in the data values

zoneCount

Defines the number of zones that should be used with the calculations for the slicing method.

When the sliceType EqualArea is used, the output raster will have zoneCounts with similar numbers of cells. When the sliceType EqualInterval is used, the output Raster will have zoneCounts, each containing equal value ranges on the output raster. When the sliceType NaturalBreaks is used, the output raster will have zonesCounts, with the number of cells in each determined by the class breaks

baseZone

When the sliceTypes EqualArea,  EqualInterval and NaturalBreaks are used, the number that is input for the baseZone identifies the value to begin assigning to the output sliced zones. The zones will begin with the value assigned to the baseZone and increment by 1.

If no base zone is specified, slice will begin the assignment at value 1.
