Calculating the Volume Data Between Two
Existing Ground Surfaces
The Surface Volume ä Existing Ground command prompts for two surface
names: the match surface and the datum surface. The match surface is the one
that will be used as the original existing ground surface, and the datum surface
is used as the new surface to compare against the match surface.
To calculate the volume data between two existing ground surfaces
1 From the Cross Sections menu, choose Surface Volume Output ä Existing
Ground to display the Select Match Surface dialog box. This dialog box displays
the names of all existing ground cross section surfaces that are defined for the
current alignment.
NOTE
If there is only one existing ground surface, the Select Match Surface dialog
box does not display. Instead, the following prompt is displayed:
Only one existing ground surface exists. Nothing to do.
2 Pick the Match surface name, and then click OK. The match surface is the initial
existing ground surface.
The Select Datum Surface dialog box is displayed, showing the same list of
surface names.
3 Select the Datum surface name, and then click OK. The datum surface is
compared against the match surface to calculate the volumes.
The following prompt is displayed:
Volume region limits (Row/Catch/Extents) <Catch>:
4 Specify which option to use for the volume region limits.
The outer limits of the volume areas are determined either by the right-of-way
(Row) offsets, the Catch points of the match slopes, or the Extents of the cross
section. The Extents option uses the complete existing ground sections limits
defined by swath widths in calculating the volume.
The following prompt is displayed:
