DTM Stakeout
117
Note: The cut/fill values accessed from the Volume button are total
volume differences between the DTM surface being staked and either
the reference DTM surface, or a reference elevation (plane). The
cut/fill values displayed in the Result card of the second Stake DTM
screen are vertical distances between the current stake point and the
reference DTM surface at the same horizontal coordinates.
The button toggles to display or hide the point names and
descriptions in the 3D view.
Datum: displays the datum elevation set in the 3D View Settings
screen.
18. Tap the Settings button to access the 3D View
Settings screen to configure the information
displayed in the 3D View screen.
When Height Exaggerated to the Maximum is
checked, the height exaggeration is automatically set to a
high value to more clearly display elevation differences
in the 3D view. When unchecked, the height
exaggeration can be set manually in the next field.
Height Exaggeration Ratio: is the value that the height
is multiplied by in the 3D view. Higher values mean
more exaggeration; a value of 1.0 would result in no
exaggeration.
When Hidden-line Removal is checked, all the lines that
occur behind other surfaces in the 3D View screen will be
hidden. The image shown here is identical to the image
shown in the screen above except the hidden lines are not
removed.
When Display Difference from Ref. DTM is checked, the vertical
portion (z-axis) of the 3D View screen is computed by the
elevation differences between the non-reference DTM surface
and the reference DTM surface. This will result in any objects
that occur above or below the reference DTM to clearly stand
out as hills and valleys and the volume information provided
in the 3D View screen will be between the staked points and
the reference DTM.
