P. Points Classification
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.
