Qimera Filter Out Soundings in Lonely Cells Dialog

How to Start

Select the Filter Out Soundings in Lonely Cells...  option of the Dynamic Surface  menu of the Main Menu toolbar. 

What it Does

This tool searches the dynamic surface for small groups of cells detached from the main body of the dynamic surface and removes them. This can be a very useful clean up as it can significantly simplify the results of operations like contouring or survey area calculation.

Upon finding a "lonely island" containing fewer than the given number of cells, all soundings in those cells are rejected and marked as filtered, causing the cells to be removed from the dynamic surface.
