TopoCoast

Available with Spatial Analyst license.

Summary

Defines a list of feature classes containing polygons that represent the coastal boundary.

Discussion

This object is used in the tool Topo To Raster.

Cells in the output raster that lie outside the coastal polygons will be set to a value that is less than the user-specified minimum height limit.

Syntax

TopoCoast (inFeatures)

Parameter	Explanation	Data Type
inFeatures [inFeature,...]	The input feature datasets.	String

Properties

Property	Explanation	Data Type
inFeatures (Read and Write)	The input feature datasets.	String

Code sample

TopoCoast example 1 (Python window)

Demonstrates how to create a TopoCoast 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"])
myTopoCliff = TopoCliff(["cliff.shp"])
myTopoCoast = TopoCoast(["coast.shp"])
myTopoExclusion = TopoExclusion(["ignore.shp"])
outTopoToRaster1 = TopoToRaster([myTopoPtElev, myTopoContour, myTopoBoundary, myTopoLake, myTopoSink, myTopoStream, myTopoCliff, myTopoCoast, myTopoExclusion])
outTopoToRaster1.save("C:/sapyexamples/output/ttraster1")

TopoCoast example 2 (stand-alone script)

Interpolates a surface with TopoToRaster using the TopoCoast class as one of the input parameters.
