Scenario: New site. In this case, there are no established coordinates on the site.
Alignment: Choose a point on site and do a one point
alignment. For the local alignment point, enter the coordinates
that you would like to use (ie 5000,5000,100). Under Configure
Field>GPS Settings, The One Pt Align Azimuth option chooses
between using true north (geodetic) or state plane north (grid). To
use real world ground distances, set the Project Scale
Factor under Configure Field>GPS Settings. Otherwise the default
scale factor of 1.0 will collect points on state plane
distances.
Scenario: One known state plane coordinate and you want to work in the state plane coordinate system.
Alignment: Either setup the base over the known state plane coordinate or do a one point alignment on this known state plane point. In Configure Field>GPS Settings, set the One Point Align Azimuth to Grid and set the scale factor to 1.0.
Scenario: Multiple known control points.
Alignment: Choose two or more control points to align to.
It is best to use control points around the perimeter of the site.
Use as many control points as are available or enough to envelope
the site. In Configure Field>GPS Settings, set the
Transformation to Plane Similarity to fit the GPS points onto the
control points and set the Project Scale Factor to 1.0. After
making the alignment, stake out another control point (ideally one
the is not used in the alignment) to make sure the alignment is
good.
