DESCRIBED BY F.J. PINTER
- The horizontal coordinates were established by classical geodetic methods and adjusted by the National Geodetic Survey in April 1998.
- The NAVD 88 height was computed by applying the VERTCON shift value to the NGVD 29 height (displayed under SUPERSEDED SURVEY CONTROL.)
- The Laplace correction was computed from DEFLEC99 derived deflections.
- The geoid height was determined by GEOID99.
