Introduction

Seafloor can automatically classify points into the following categories:

  • Shoals
  • Deeps
  • Ridges
  • Saddles
  • Valleys

The user can specify the search radius and angle, where applicable. The points will be saved as separate datasets in a classification folder under each chart.

This exercise expects that the project already contains at least one chart and a corresponding Seafloor surface.

Exercises

  1. On the Utilities (2) tab in the Seafloor Main Menu, click Point Classification.

  6. Click Execute.

The resulting datasets can be found in the classification folder under the chart.
