TopoContour

需要 Spatial Analyst 许可。

摘要

定义线要素类列表,这些线要素类表示等值线以及标识其高程值的字段。

说明

此对象用于地形 (topo) 转栅格工具。

语法

 TopoContour (inFeatures)
参数说明数据类型
inFeatures
[[inFeature, {field}],...]

输入线要素数据集。

或者,可以提供存储高程值的字段名称以用于输入线。

List

属性

属性说明数据类型
inFeatures
(可读写)

用于属性的输入要素数据集和字段。

TopoContour 示例 1(Python 窗口)

演示如何创建 TopoContour 类以及如何在 Python 窗口的 TopoToRaster 工具中使用该类。

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")
TopoContour 示例 2(独立脚本)

使用 TopoContour 类作为其中一个输入参数,通过 TopoToRaster 插入一个表面。

# 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")
