BASIS OF SURVEY DATUM

This project was surveyed on the Montana State Plane Zone 2500 Coordinate System using RTK GPS. The project was brought to ground at survey control point CP-1. The geodetic datum is NAD83(CONUS). The vertical datum is NAVD 88 (GEOID12B). Horizontal units are International Feet. Vertical units are US Survey Feet.

Project control was established by OPUS Position at point 1. Values for Points 2-4 were determined by redundant RTK GPS observations from Point 1.
