Smooth Bathymetric TIN (Maritime)

Synthèse

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.

Utilisation

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

  Remarque :

  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 option is checked. A unique name must be used for each TIN generated in a common workspace.

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")
