Parameters

geoDataset [in]

  geoDataset is a parameter of type IGeoDataset

Points [in]

  Points is a parameter of type IPointCollection

selectInside [in]
  selectInside is a parameter of type VARIANT_BOOL
outGeodataset [out, retval]

  outGeodataset is a parameter of type IGeoDataset

Product Availability

Remarks

geoDataset

an input Raster, RasterDataset, RasterBand, or RasterDescriptor

The geoDataset identifies the cell values which will be selected inside or outside a specified point.

Points

an IPointsCollection identifying the coordinates of the points to be selected

The coordinates are specified in map units and are in the same units as the geoDataset.

selectInside

a Boolean specifying which cells should be selected, those contained in or external to, the cell containing the selected point

If True, the cell in which the selected point falls will be written to the output Raster. All cells outside the box will receive NoData on the output Raster.

If the Boolean is False, the cells outside the input cells should be selected and written to the output Raster. The cell within which the selected point falls will receive NoData on the output Raster.
