Resumen
Defines a list of feature classes containing polygons that represent the outer boundary of the output raster.
Debate
This object is used in the tool Topo To Raster.
Cells in the output raster outside this boundary will be NoData. This option can be used for clipping out water areas along coastlines before making the final output raster.
The boundary polygons define the locations within which the calculations will be performed.
