An overview of topo classes

Available with Spatial Analyst license.

The topo classes define the input data to be used in the creation of the interpolated surface raster.

TopoBoundary	Defines a list of feature classes containing polygons that represent the outer boundary of the output raster.
TopoCliff	Defines a list of line feature classes of cliff locations.
TopoCoast	Defines a list of feature classes containing polygons that represent the coastal boundary.
TopoContour	Defines a list of line feature classes that represent contours and the fields identifying their elevation values.
TopoExclusion	Defines a list of feature classes containing polygons that represent areas of data that will be excluded.
TopoLake	Defines a list of polygon feature classes that specify the location of lakes.
TopoPointElevation	Defines a list of point feature classes representing surface elevations and the fields identifying their elevation values.
TopoSink	Defines a list of point feature classes that represent the locations and magnitude of known topographic depressions and the fields identifying their elevation values.
TopoStream	Defines a list of line feature classes of stream locations.
