TopoCoast 示例 1（Python 窗口）

演示如何在 Python 窗口下创建 TopoCoast 类，并通过 TopoToRaster 工具使用该类。

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 示例 2（独立脚本）

将 TopoCoast 类作为一项输入参数，通过 TopoToRaster 工具插值成面。

# Name: TopoBoundary_Ex_02.py
# Description: Run 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"])
# Run TopoToRaster
outTopoToRaster = TopoToRaster([myTopoPtElev, myTopoContour, myTopoBoundary, myTopoLake, myTopoSink, myTopoStream])
# Save the output
outTopoToRaster.save("C:/sapyexamples/output/ttraster2")
