 AD1481.This mark is at Charlotte County Airport (PGD)
 AD1481
 AD1481.The horizontal coordinates were scaled from a topographic map and have
 AD1481.an estimated accuracy of +/- 6 seconds.
 AD1481
 AD1481.The orthometric height was determined by differential leveling
 AD1481.and adjusted by the National Geodetic Survey in June 1991.
 AD1481
 AD1481.The geoid height was determined by GEOID99.
 AD1481
 AD1481.The dynamic height is computed by dividing the NAVD 88
 AD1481.geopotential number by the normal gravity value computed on the
 AD1481.Geodetic Reference System of 1980 (GRS 80) ellipsoid at 45
 AD1481.degrees latitude (g = 980.6199 gals.).
 AD1481
 AD1481.The modeled gravity was interpolated from observed gravity values.
