TopoExclusion

汇总

定义排除特定数据区域的面要素类列表。

讨论

此对象用于 地形 (topo) 转栅格 工具。

这样可从插值过程中移除堤壁和桥的高程数据，从而可实现基础山谷结构的插值。

移除的通常是与实际地表中相关联的会阻断真实地表形状和地形结构的要素数据。

TopoExclusion 示例 1（Python 窗口）

演示如何创建 TopoExclusion 类，并在 Python 窗口内 TopoToRaster 工具中使用 TopoExclusion 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")

TopoExclusion 示例 2（独立脚本）

使用 TopoExclusion 类作为一项输入参数，通过 TopoToRaster 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")
