Datum : displays the datum elevation set in the 3D View Settings
screen.
17. Tap the
6HWWLQJ button at the top of the screen to access the 3D
View Setting 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. 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.
The higher this value, the more
exaggeration, where 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 the Difference is checked, the
elevations in the 3D View screen will be distorted
so the reference DTM becomes a flat surface. This will result in any
staked points 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.
When the Display the Difference checkbox is unchecked, the Datum
field can be set to a reference elevation. Cut and fill volumes in the
3D View screen will then be based on the difference of a horizontal
plane at the elevation specified here and the staked points.
The View Direction (from view point to the center) settings allow you
to specify the exact horizontal and vertical angle in which to view the
DTM surface.
