TopoContour

Disponible con una licencia de Spatial Analyst.

Resumen

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

Debate

This object is used in the tool Topo To Raster.

Sintaxis

 TopoContour (inFeatures)
ParámetroExplicaciónTipo de datos

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"])
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")
TopoContour example 2 (stand-alone script)

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

# Name: TopoBoundary_Ex_02.py
# Description: Execute TopoToRaster using all the supported objects.
# Requirements: Spatial Analyst Extension

# Import system modules
import arcpy
from arcpy import env
from arcpy.sa import *

# Set environment settings
env.workspace = "C:/sapyexamples/data"

# Create all the supported Objects
 
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"])
# Execute TopoToRaster
outTopoToRaster = TopoToRaster([myTopoPtElev, myTopoContour, myTopoBoundary, myTopoLake, myTopoSink, myTopoStream])
# Save the output 
outTopoToRaster.save("C:/sapyexamples/output/ttraster2")
