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.

; Hidden-line Removal: When checked, will hide

all the lines that occur behind other surfaces in the

3D View. The image shown here is identical to the

image shown on Page R-89 except the hidden lines

are n

ot removed.

; Display the Difference: This applies only to DTM

stakeout. When 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.

When 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

non-reference DTM surface.

Datum: When the Display the Difference checkbox is unchecked, cut

and fill volumes will be computed in the 3D View

screen based on the

difference of a horizontal plane at the elevation specified here and the

staked points.

View Direction (from view point to the center): allows you to

specify the exact horizontal and vertical angle in which to view the

DTM.
