复制 TIN (3D 分析)

摘要

创建不规则三角网 (TIN) 数据集的副本。

用法

• 指定 PRE_10.0 选项来创建向后兼容的 TIN 副本，该副本可用于在 10.0 之前发布的 ArcGIS 版本。

• 指定 CURRENT 选项以使用 10.0 规范创建 TIN 副本，其提供以下增强功能：

  • 支持增强的空间参考信息
  • 支持约束型 Delaunay 三角测量
  • 结点源信息的持久性，使得每个结点都能存储有关结点源自输入数据还是由三角仪引入的信息。
  • 边标签值的持久性

语法

CopyTIN_3d (in_tin, out_tin, {version})

参数	说明	数据类型
in_tin	The input TIN.	TIN Layer
out_tin	The output TIN dataset.	TIN
version （可选）	输出 TIN 的版本。 CURRENT —ArcGIS 10.0 中的当前 TIN 版本，支持约束型 Delaunay 三角测量。这是默认设置。 PRE_10.0 —在 ArcGIS 10.0 之前支持的 TIN 版本，仅支持符合 Delaunay 的三角测量。	String

代码示例

CopyTIN 示例 1（Python 窗口）

The following sample demonstrates the use of this tool in the Python window:

import arcpy
from arcpy import env

arcpy.CheckOutExtension("3D")
env.workspace = "C:/data"
arcpy.CopyTin_3d("elevation", "elevation_copy", "CURRENT")

CopyTIN 示例 2（独立脚本）

The following sample demonstrates the use of this tool in a stand-alone Python script:

'''****************************************************************************
Name: Define Data Boundary of LAS File
Description: This script demonstrates how to delineate data boundaries of 
             LAS files with irregularly clustered points. It is intended for 
             use as a script tool with one input LAS file.
****************************************************************************'''
# Import system modules
import arcpy
import exceptions, sys, traceback

# Set local variables
inLas = arcpy.GetParameterAsText(0) #input LAS file
ptSpacing = arcpy.GetParameterAsText(1) # LAS point spacing
classCode = arcpy.GetParameterAsText(2) # List of integers
returnValue = arcpy.GetParameterAsText(3) # List of strings
outTin = arcpy.GetParameterAsText(4) # TIN created to delineate data area
outBoundary = arcpy.GetParameterAsText(5) # Polygon boundary file

try:
    arcpy.CheckOutExtension("3D")
    # Execute LASToMultipoint
    arcpy.AddMessage("Creating multipoint features from LAS...")
    lasMP = arcpy.CreateUniqueName('lasMultipoint', 'in_memory')
    arcpy.ddd.LASToMultipoint(inLas, LasMP, ptSpacing, class_code, 
                             "ANY_RETURNS", "", sr, inFormat, zfactor)
    # Execute CreateTin
    arcpy.AddMessage("Creating TIN dataset...")
    arcpy.ddd.CreateTin(outTin, sr, "{0} Shape.Z masspoints"\
                       .format(lasMP), "Delaunay")
    # Execute CopyTin
    arcpy.AddMessage("Copying TIN to delineate data boundary...")
    arcpy.ddd.CopyTin(outTin, "{0}_copy".format(outTin))
    # Execute DelineateTinDataArea
    arcpy.AddMessage("Delineating TIN boundary...")
    maxEdge = ptSpacing * 4
    arcpy.ddd.DelineateTinDataArea(outTin, maxEdge, "PERIMETER_ONLY")
    # Execute TinDomain
    arcpy.AddMessage("Exporting data area to polygon boundary...")
    arcpy.ddd.TinDomain(outTin, outBoundary, "POLYGON")
    arcpy.AddMessage("Finished")
    arcpy.CheckInExtension("3D")
        
except arcpy.ExecuteError:
    print arcpy.GetMessages()
except:
    # Get the traceback object
    tb = sys.exc_info()[2]
    tbinfo = traceback.format_tb(tb)[0]
    # Concatenate error information into message string
    pymsg = 'PYTHON ERRORS:\nTraceback info:\n{0}\nError Info:\n{1}'\
          .format(tbinfo, str(sys.exc_info()[1]))
    msgs = 'ArcPy ERRORS:\n {0}\n'.format(arcpy.GetMessages(2))
    # Return python error messages for script tool or Python Window
    arcpy.AddError(pymsg)
    arcpy.AddError(msgs)
