Wow, there has been a lot of ink spilt on North Arrows and projection declarations for jobs based on GPS data.
Since I am not a licensed surveyor, my opinion does not count. But I get asked all the time. So here is an example of what I might do as a minimum:
I, Joe Blow, do hereby certify that I am a Professional Land Surveyor, holding certificate 99999 as prescribed by the State of Chaos. I further certify that I have prepared the diagram represented herein and that the same is an accurate representation of a survey, and was conducted under my direct supervision. Benchmark The Benchmark for this project is CP201 Coordinate System and Projection Information Horizontal Datum = NAD83, North American Datum 1983, 2011 Realization 2010.0 Epoch GPS Control = Maine DOT Virtual Reference System (VRS) Vertical Datum = NAVD88, North American Vertical Datum of 1988, GPS Derived GEOID (used for GPS Derived Heights) = GEOID12B (NGS) Ellipsoid = GRS1980 Projection = Maine West NAD83 State Plane Coordinates Distance = US Survey Feet (1 Meter = 3937/1200 US Survey Feet) Distances Distances are Grid distances converted to Ground using a Combined Scale Factor The Combined Scale Factor (0.99996067) for this project was derived at Control Point 201 CP201 = 44 2 55.34000 N 69 58 23.05000 W NAD83 Ellipsoid Height 215.562 ft GEOID -57.100 ft Ortho Height 272.662 ft [NAVD88 (Computed using GEOID12B)] Example: 9,857.824 SFeet Grid = 9,858.206 SFeet Ground Bearings Bearings are with respect to State Plane Grid North Declination at TN-SP 0° 8’ 4.57” TN-MN 15° 36’ 37” (2017 Estimate)
