Smooth Bathymetric TIN (Maritime)

获得 Maritime Bathymetry 许可后可用。

摘要

Smooths a triangulated irregular network (TIN) dataset in a manner that strictly preserves a shallow bias.

The output is used to generate depth contours used for navigation, so the output TIN nodes will never report a value deeper than the input.

使用情况

• The Smoothing Iterations parameter value should be determined experimentally, based on the scale of the desired output and aesthetics.

  注：

  The iteration count should increase for smaller scale charts to apply more generalization appropriate for the scale.

• The output TIN can be used to generate smoothed depth contours.

参数

对话框

标注	说明	数据类型
Input TIN	The input TIN that will be smoothed with a shallow bias.	TIN Layer
Output TIN	The output smoothed TIN.	TIN
Depth Direction	Specifies how the depth will be captured in the input TIN. Positive Up—The depth will be captured in the input TIN. This is default. Positive Down—The downward depth will be captured in the input TIN.	String
Smoothing Iterations	The number of smoothing passes that will be performed over the TIN.	Long

SmoothBathymetricTIN example (Python window)

The following Python window script demonstrates how to use the SmoothBathymetricTIN tool.

import arcpy
arcpy.CheckOutExtension("Bathymetry")
# Input TIN
inTIN = r"C:\Data\smooth\seattle"
# Output TIN
outputTIN = r"C:\Data\smooth\seattle_smooth"
arcpy.SmoothBathymetricTIN_maritime(inTIN, outputTIN, “POSITIVE_UP”, 25)
arcpy.CheckInExtension("Bathymetry")
