Documented History (by the NGS)
|01/12/1999 by NGS (MONUMENTED)
|DESCRIBED BY NATIONAL GEODETIC SURVEY 1999 (CSM)
RECOVERED AS DESCRIBED.
- ITRF positions are available for this station. The horizontal coordinates were established by GPS observations and adjusted by the National Geodetic Survey in July 1996. The horizontal coordinates are valid at the epoch date displayed above. The epoch date for horizontal control is a decimal equivalence of Year/Month/Day.
- The orthometric height was determined by GPS observations and a high-resolution geoid model.
- The X, Y, and Z were computed from the position and the ellipsoidal ht.
- The Laplace correction was computed from DEFLEC99 derived deflections.
- The ellipsoidal height was determined by GPS observations and is referenced to NAD 83.
- The geoid height was determined by GEOID99.
