TopoContour

Récapitulatif

Defines a list of line feature classes that represent contours and the fields identifying their elevation values.

Discussion

This object is used in the tool Topo To Raster.

Syntaxe

TopoContour (inFeatures)

Paramètre	Explication	Type de données
inFeatures [[inFeature, {field}],...]	The input line feature datasets. Optionally, you can supply the name of a field that stores the elevation values to use for the input lines.	List

Propriétés

Propriété	Explication	Type de données

Exemple de code

TopoContour example 1 (Python window)

Demonstrates how to create a TopoContour 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")

TopoContour example 2 (stand-alone script)

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