TopoLake
汇总
定义面要素类列表，这些面要素类指定湖泊位置。
讨论
此对象用于 地形 (topo) 转栅格 工具。
湖面内的所有输出栅格像元均将指定为使用沿湖岸线所有像元高程值中最小的那个高程值。

代码示例
TopoLake 示例 1（Python 窗口）
演示如何创建 TopoLake 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")
TopoLake 示例 2（独立脚本）
使用 TopoLake 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: 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")
