Start GPS Survey - Solve Localization
The Start GPS Survey Solve Localization screen is
displayed when you need a horizontal adjustment to
solve your coordinate system. A horizontal adjustment is
required to solve your coordinate system any time you
begin a survey from an autonomous base position. This
is always the case when your projection mode is Ground
– TDS Localization
, since your first base setup is always
from an autonomous GPS position. This may be the case
when your projection mode is Mapping Plane, when you
set your first base on a new point. A vertical adjustment
is often desired, although not required before data
collection can begin.
The horizontal and vertical adjustments are usually
solved together. First, tap Collect Control> to occupy
some existing local points as GPS Control points. Next,
tap Solve Localization … to open the Solve Localization wizard to
calculate the horizontal and vertical adjustment parameters (Page
288).
After you successfully solve the localization adjustment, the Start
GPS Survey wizard will close, and the GPS Data Collection screen
will open (Page 301). You are now ready to measure and store new
points in this job.
You can also choose to start the survey without solving the
localization, and complete the required adjustment later. Tap Start
Survey Now > to apply a temporary localization and begin data
collection. Any time during the survey, you can occupy the required
control points and solve the localization parameters. The GPS data
collected points will be updated to the proper local coordinate after
the localization is solved.
