TopoLake
Summary
Defines a list of polygon feature classes that specify the location of lakes.
Discussion
This object is used in the tool Topo To Raster.
All output raster cells within a lake will be assigned to the minimum elevation value of all cells along the shoreline.

Code Sample
TopoLake example 1 (Python window)
Demonstrates how to create a TopoLake class and use it in the TopoToRaster tool within the Python window.
import arcpy from arcpy import env from arcpy.sa import * env.workspace = "C:/sapyexamples/data" myTopoPtElev = TopoPointElevation([["spots.shp", "spot_meter"], ["spots2.shp", "elev"]]) myTopoContour = TopoContour([["contours.shp", "spot_meter"]]) myTopoBoundary = TopoBoundary(["boundary.shp"]) myTopoLake = TopoLake(["lakes.shp"]) myTopoSink = TopoSink([["sink1.shp", "elevation"], ["sink2.shp", "NONE"]]) myTopoStream = TopoStream(["streams.shp"]) outTopoToRaster1 = TopoToRaster([myTopoPtElev, myTopoContour, myTopoBoundary, myTopoLake, myTopoSink, myTopoStream]) outTopoToRaster1.save("C:/sapyexamples/output/ttraster1")
TopoLake example 2 (stand-alone script)
Interpolates a surface with TopoToRaster using the TopoLake class as one of the input parameters.
