Every capture session is entered into the vmCapture table and, therefore, you cannot make any
changes using the Grid Manager during a session without saving the current vmCapture table.
Changes include adding or removing other grid files or making existing ones active or inactive.
Vertical Mapper always prompts you to save the current vmCapture table to another name.
The Cursor Tracking check box enables you to continually update the Grid Info dialog box with
values from the active grids in the Grid Manager by moving the mouse cursor.
You cannot use the Capture Data and the Cursor Tracking options at the same time.
Using the Region Info Tool
The Region Info tool displays a statistical summary of the data within a selected region. The values
displayed are for the grid highlighted in the Grid Manager. To display statistical information for a
large number of regions contained in the same table, use the Region Inspection function. For more
information about region inspection, see
The Region Inspection Function on page 132 .
1. On the Vertical Mapper toolbar, click the Region Info button .
2. Select a region in the Map window.
Note The Volume calculation is the sum of all the values found in the region multiplied by the cell
dimensions. This value is only meaningful when the z-unit is a linear measurement. The %
null value indicates how much of the enclosed area contains null values.
