North American Vertical Datum of 1988 (NAVD 88)

The orthometric height is the vertical distance H along the plumb line from a point of interest to a reference surface known as the geoid, the vertical datum that approximates mean sea level. Orthometric height is one of the scientific formalizations of a laypersons' "height above sea level", along with other types of heights in Geodesy. In the US, the current NAVD88 datum is tied to a defined elevation at one point rather than to any … WebFor field work in the USA, you will want to select GEOID 18/NAVD88 (NAD83 2011). The geoid model will download to your device. Once downloaded, select the model by simply tapping on it (a selection checkmark will appear to the right). Then, tap Done. Back in your Eos Tools Pro position tab, you will now see your orthometric height. Congratulations! newsmailler
