Remarks
|
GeoDataset |
an input Raster, RasterDataset, RasterBand, or RasterDescriptor to be contoured |
|
inputPoint |
an input point feature defined by a point object using IPoint interface which the resulting contour or isoline will pass through |
|
contourLine |
the output contour or isoline polyline object which represents the constant cell values of the input point. |
|
elevation |
an output double value which represents the cell value that the input point intersects with in the input GeoDataset. This value therefore can be used to describe the value of the output contour line |
