Smooth Bathymetric TIN (Maritime)

Disponible con licencia de Maritime Bathymetry.

Resumen

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

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

Uso

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

  Nota:

  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.

• The output TIN cannot be overwritten even when the Allow geoprocessing tools to overwrite existing datasets check box is checked on the Geoprocessing tab on the Options dialog box. A unique name must be used for each TIN generated in a common workspace.

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

SmoothBathymetricTIN example (Python window)

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

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