Place you base near the monument (somewhere appropriate).You have the horizontal and vertical datum downloaded in the Reachview3 app.You know the ortho elevation but not sure how and what to do with the ellipsoid.
#Vertical datum conversion how to
You know the coordinates of the monument but can not feed it directly into the base without a transformation or you dont know how to.At least now in the current firmware version This is a great scenario for the base shift feature. The tie sheets also show latitude and longitude. Our survey monuments use NAD83 Utah state plane (North, Central, or South) as the coordinate system and WGS84 datum with ortho feet (NAVD88 (Geoid18). Using this on the Rover how should the Base be set up?
PROGRAM = datasheet95, VERSION = 8.12.5.14ġ National Geodetic Survey, Retrieval Date = OCTOBER 20, 2021 See file dsdata.pdf for more information about the datasheet. Using the partial DS shown below you would take the “*NAVD 88 ORTHO HEIGHT” (1668.001 m) and add the “GEOID HEIGHT” (-17.521 m) will give you a ellipsoid height of 1650.480 m. The NGS Data Sheet (DS) that you probably already have, gives you the information you need.
