Rotation: The adjusted coordinates can be rotated in one of two ways.
Given Azimuth or Bearing – Enter names of From and To points in the network plus
the azimuth or bearing you want to exist between these two points in the computed
ground file. When units are in DMS, you can enter an azimuth (45-22-33) or a
quadrant bearing (S45-22-33E). When units are in GONS, you can enter an azimuth
only (50.1234).
Given Rotation – Enter the positive or negative rotation you would like applied to
the coordinates. (Examples, 2-35-46.76 in DMS, -15.12457 in GONS.) A positive
rotation value is clockwise.
Translation: The coordinates can be translated using one of two methods.
Coordinates at a Station – Enter the name of a point in the network you want to be
assigned specific coordinates. There are two ways coordinates can be assigned:
1. Use Adjusted Coordinates – Coordinate values computed for the point during the
adjustment run are assigned to the that point in the ground file. The result of this
is that the ground coordinates for the named point will be exactly the same as its
grid coordinates, and the remining ground points will have coordinates slightly
different than their grid coordinates because of the scaling.
2. Use Given Coordinates – Coordinate values that you enter are assigned to that
point in the ground file.
Arbitrary Coordinates – Choose this method if you don’t care what values are
assigned to the ground points. Coordinates in the computed ground file will be
shifted an arbitrary amount so that they will look “different” than the adjusted
network coordinates.
