This project uses a custom local coordinate system. The coordinate system started as the Montana State Plane Coordinate System, and was brought to ground at CP-1 with a ground scale factor of 1.0005678742. To avoid confusion with true SPC coordinates, project coordinates were truncated 1,300,000 in the northing and 2,500,000 in the easting. The geodetic datum is NAD 1983 (2011) as determined by OPUS. The vertical datum is NAVD88 as determined by GEOID12A. Units: international feet for horizontal, survey feet for vertical.
For the purposes of this project, mapping grid values and distances are equal to true ground distances. The convergence angle at CP-1 is +1°46'59"; the convergence angle at CP-2 is +1°47'07"; the convergence angle at CP-3 is +1°47'10". Complete Cartesian and geodetic control values are shown below.
DOWL established project control with redundant OPUS positions at CP 1. Values for points CP-2and CP-3 were determined by redundant RTK GPS observations from CP-1.
