 JS4673.ITRF positions are available for this station.
 JS4673.The horizontal coordinates were established by GPS observations
 JS4673.and adjusted by the National Geodetic Survey in February 2007.
 JS4673
 JS4673.The datum tag of NAD 83(2007) is equivalent to NAD 83(NSRS2007).
 JS4673.See National Readjustment for more information.
 JS4673.The horizontal coordinates are valid at the epoch date displayed above.
 JS4673.The epoch date for horizontal control is a decimal equivalence
 JS4673.of Year/Month/Day.
 JS4673
 JS4673.The orthometric height was determined by GPS observations and a
 JS4673.high-resolution geoid model.
 JS4673
 JS4673.Photographs are available for this station.
 JS4673
 JS4673.The X, Y, and Z were computed from the position and the ellipsoidal ht.
 JS4673
 JS4673.The Laplace correction was computed from DEFLEC09 derived deflections.
 JS4673
 JS4673.The ellipsoidal height was determined by GPS observations
 JS4673.and is referenced to NAD 83.
 JS4673
 JS4673.The geoid height was determined by GEOID09.

 JS4673'TAHOE AND 5 MI (8.0 KM)  SOUTHWEST OF THE DAM AT SILVER LAKE.
 JS4673'TO REACH THE STATION FROM THE DAM AT SILVER LAKE, GO SOUTHWESTERLY FOR
 JS4673'4.3 MI (6.9 KM)  ON STATE HIGHWAY 88 TO DEVILS GARDEN VISTA POINT.
 JS4673'CONTINUE FOR 0.35 MI (0.56 KM)  ON HIGHWAY 88 TO A ROAD CONNECTION
 JS4673'AND THE STATION ON THE RIGHT.  THE ROAD CONNECTION LOOPS BACK
 JS4673'APPROXIMATELY PARALLEL TO HIGHWAY 88 TO THE EAST.
 JS4673'THE STATION IS A 3.5 IN DIAMETER CADT BRASS DISK SET AT THE WESTERLY
 JS4673'END OF A BEDROCK OUTCROPPING ABOUT 1 X 2 FOOT AND ABOUT 0.5 FT
 JS4673'(0.2 M)  ABOVE GROUND.  LOCATED 57.8 FT (17.6 M)  NORTH OF THE
