Inclination is the angle measured from the horizon to the line of sight at either the viewing
location or the focus point, depending on the selected viewing mode. If the From and To mode is
chosen, the Inclination setting is applicable. When the From Your Location mode is chosen, the
inclination is the angle from the horizon to the line of sight at the viewing location. When the To
Your Location mode is chosen, the inclination is the angle from the horizon to the line of sight at
the focus point.
•
Distance is the distance between the viewing location and the focus point and is expressed in
the coordinate units of the master grid. You can modify this value by entering a new value in the
edit dialog box or by moving the slider bar to the left or right. When the slider bar is in use
(indicated by the dashed line around it), the arrow keys can be used to modify this value. This
setting is only available for the To Your Location viewing mode.
The Looking To section defines the x-, y- and z- coordinates of the location the viewer is looking
towards. The x, y coordinate pair specifies the surface position, and the z-value specifies the
distance above or below the surface elevation. These values must be expressed in the units of the
coordinate system being used by the master grid. The default x-, y-coordinate pair corresponds to
the geographic centre of the master grid. The default z-value is the lowest value in the master grid.
You can modify these settings by entering a new value in the edit dialog box or by moving the slider
bar to the left or right. When the slider bar is in use (indicated by the dashed line around it), the arrow
keys can be used to modify this value.
In the From Your Location mode, the
azimuth is the direction the viewer is
looking toward in relation to the
viewing location.
In the To Your Location mode, the
azimuth is the direction the viewer is
looking toward in relation to the focus
point.
