ISurfaceOp.ContoursAsPolylines Method

Creates multiple contours or isolines that pass through specified points on a surface.

[Visual Basic .NET]
Public Sub ContoursAsPolylines ( _
    ByVal GeoDataset As IGeoDataset, _
    ByVal inputPoints As IPointCollection, _
    ByRef contourLines As IGeometryCollection, _
    ByRef outputPointsWithElevations As IPointCollection _
)

[C#]
public void ContoursAsPolylines (
    IGeoDataset GeoDataset,
    IPointCollection inputPoints,
    ref IGeometryCollection contourLines,
    ref IPointCollection outputPointsWithElevations
);

[C++]
HRESULT ContoursAsPolylines(
  IGeoDataset* GeoDataset,
  IPointCollection* inputPoints,
  IGeometryCollection** contourLines,
  IPointCollection** outputPointsWithElevations
);

[C++]

Parameters
GeoDataset [in]

  GeoDataset is a parameter of type IGeoDataset
inputPoints [in]

  inputPoints is a parameter of type IPointCollection
contourLines [out]

  contourLines is a parameter of type IGeometryCollection
outputPointsWithElevations [out]

  outputPointsWithElevations is a parameter of type IPointCollection

Product Availability

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

Remarks

GeoDataset	an input Raster, RasterDataset, RasterBand, or RasterDescriptor to be contoured
inputPoints	a input collection of points using IPointCollection which specifies where multiple contours or isolines will pass through.
contourLines	the output collection of polylines from IGeometryCollection representing multiple contour or isolines that identify the constant cell values of the input points.
outputPointsWithElevations	an output point collection which can be used to obtain the cell value (z attribute) of the (i)th point object that intersects with input GeoDataset thus describing the value of the (i)th output contour line
