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.
