 HV0364.The horizontal coordinates were determined by differentially corrected
 HV0364.hand held GPS observations or other comparable positioning techniques
 HV0364.and have an estimated accuracy of +/- 3 meters.

 HV0364.The orthometric height was determined by differential leveling and
 HV0364.adjusted by the NATIONAL GEODETIC SURVEY
 HV0364.in June 1991.

 HV0364.The dynamic height is computed by dividing the NAVD 88
 HV0364.geopotential number by the normal gravity value computed on the
 HV0364.Geodetic Reference System of 1980 (GRS 80) ellipsoid at 45
 HV0364.degrees latitude (g = 980.6199 gals.).

 HV0364.The modeled gravity was interpolated from observed gravity values.
