; Survey with True Azimuths : automates the process of adjusting
the circle on the total station when traversing so that you can survey
with azimuths rather than horizontal angles (see Page R-127).
; Use Scale Factor : when checked, horizontal distances to all new
points will be scaled by the factor entered here. (Elevations are not
affected.) This defaults to unchecked when a new job is created.
Calc. Scale : allows you to automatically compute the scale factor
from a selected map projection. If a mapping plane is not already
selected, you will first be prompted to select one.
; Prompt to Reset Scale on New Setups : if checked when a map
projection is selected and you set up over a new location, the specified
scale factor is compared to the scale factor defined for your current
location in the mapping plane. If the scale factor is different, you will
be prompted to use the new scale factor.
