Smooth Bathymetric TIN

Zusammenfassung

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.

Verwendung

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

    Hinweis:

    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.

Syntax

SmoothBathymetricTIN(in_tin, out_tin, depth_direction, smoothing_iterations)
ParameterErklärungDatentyp
in_tin

The input TIN that will be smoothed with a shallow bias.

TIN Layer
out_tin

The output smoothed TIN.

TIN
depth_direction

Specifies how the depth will be captured in the input TIN.

  • POSITIVE_UPThe depth will be captured in the input TIN. This is default.
  • POSITIVE_DOWNThe downward depth will be captured in the input TIN.
String
smoothing_iterations

The number of smoothing passes that will be performed over the TIN.

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")
