NAVD 88 (The North American Vertical Datum of 1988) is a vertical geodetic datum created in 1991 from measurements in Mexico, the US, and Canada. NAVD 88 was computed due to land distortions over time from the NGVD 29 measurements. Conversion to NGVD 29 is done by interpolating between data points between the two data.
