Qimera Create Clipped Grid

Create Clipped Dynamic Grid

Starting Qimera v2.7.0 the Create Clipped Dynamic Grid feature has been eclipsed by the Duplicate Dynamic Grid. This feature will no longer be required and the documentation will be removed.

How to Start

• Create Clipped Surrface option from Dynamic Grid menu of Main Menu bar

What it Does

This dialog allows you to create a clipped grid of the currently selected grid.  You are able to select the depth range that you desire in the final dynamic grid that is created.

General Description

This feature will clone the currently selected grid and run a clipping filter on all the cells for the grid.  This occurs for all layers within the grid (shallow, deep, average, CUBE).  If the cell depth is outside the clipping range, the cell will be marked as invalid.  It should be noted that no soundings are rejected during this operation.  This capability can be used to aid in cleaning data within a certain depth range.  All exports, including those of CUBE grid, will only export the remaining valid cells of your clipped grid.

Editing Clipped Grids

Clipped grids are in reality just another Dynamic Grid.  When they are created, the Update option for the grid is set to Always.  What this means is that if you edit soundings that are part of the original clipped grid, this grid will update and Re-Clip itself.  If you don't want this grid to continually update during edit operations, simply change the Update option to Manual.   However, if you need to update soundings that are part of the clipped grid, you can allow Qimera to perform an update operation or use the right-click context menu of the grid to request Update Dynamic grid From Edits. After any type of update operation, automatic or manual, Qimera will re-clip the grid to the originally specified depth range.
