The orthometric height was determined by differential leveling and adjusted in June 1991.

The geoid height was determined by GEOID09.

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

The horizontal coordinates were established by GPS observations and adjusted by the National Geodetic Survey in February 2007.

The datum tag of NAD 83(2007) is equivalent to NAD 83(NSRS2007). See www.ngs.noaa.gov/NationalReadjustment for more information. 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 differential leveling and adjusted in September 1998. WARNING-GPS observations at this control monument resulted in a GPS derived orthometric height which differed from the leveled height by more than one decimeter (0.1 meter).

The X Y and Z were computed from the position and the ellipsoidal ht.

The Laplace correction was computed from USDV2009 derived deflections.

The ellipsoidal height was determined by GPS observations and is referenced to NAD 83.

The geoid height was determined by GEOID09.

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

STATION DESCRIPTION

DESCRIBED BY US GEOLOGICAL SURVEY 1950 (RLE) THE STATION IS LOCATED ABOUT 1-1/2 MILES NORTHWEST OF IDA ON THE SOUTH SIDE OF THE LOUISIANA-ARKANSAS STATE LINE AND IN THE NORTHWEST CORNER OF A PASTURE ON THE EAST SIDE OF A NORTH-SOUTH GRADED ROAD. IT IS 115 FEET SOUTHEAST OF THE SOUTHEAST CORNER OF HOUSE 48 FEET EAST OF THE CENTER OF CURVE IN ROAD 35 FEET SOUTH OF EAST-WEST FENCE LINE AND 7 FEET EAST OF WITNESS POST AND FENCE LINE. IT IS A U.S.G.S. BENCH MARK DISK SET IN A 6 BY 6 INCH CONCRETE POST PROJECTING 4 INCHES AND STAMPED TT 120 1932.

REFERENCE MARK NO 2 IS WEST-NORTHWEST OF THE STATION 20 FEET NORTH OF THE CENTER OF ROAD AND 1 FOOT EAST OF FENCE CORNER IN THE SOUTHWEST CORNER OF THE YARD. IT IS STAMPED TT 120 NO 2 1950 AND SET FLUSH WITH THE GROUND SURFACE.

REFERENCE MARK NO 1 IS NORTH-NORTHEAST OF THE STATION SET IN THE OPEN PASTURE 94 FEET EAST OF THE EAST SIDE OF HOUSE. IT IS STAMPED TT 120 NO 1 1950 AND SET FLUSH WITH THE GROUND SURFACE.

THE DISTANCE BETWEEN REFERENCE MARK NO 1 AND REFERENCE MARK NO 2 IS 149.30 FEET.

THE AZIMUTH MARK IS ABOUT 0.3 MILE SOUTH-SOUTHEAST OF THE STATION 20 FEET SOUTH OF THE CENTER OF ROAD 1 FOOT EAST OF FENCE CORNER AND 1 FOOT NORTH OF WITNESS POST. IT IS STAMPED TT 120 1950 AND PROJECTS 4 INCHES.

TO REACH THE STATION FROM THE JUNCTION OF STATE ROUTE 991 AND U.S. HIGHWAY NO 71 GO WEST ON STATE ROUTE 991 FOR 0.45 MILE TO FORKS BEAR RIGHT AND FOLLOW STATE LINE ROAD FOR 1.15 MILES TO THE AZIMUTH MARK ON THE LEFT AS DESCRIBED CONTINUE NORTH ON GRADED ROAD FOR 0.3 MILE TO WHERE ROAD MAKES A LEFT TURN AND STATION ON RIGHT IN FENCE CORNER AS DESCRIBED.

THE STATION SURFACE MARK AND REFERENCE MARK NO. 2 WERE FOUND TO BE DISTURBED. THE STATION SURFACE MARK WAS PLUMBED IN OVER THE UNDERGROUND STATION MARK. A NEW REFERENCE MARK NO. 3 AND AN AZIMUTH MARK WERE ESTABLISHED.

FOLLOWING IS A NEW AND COMPLETE DESCRIPTION--

THE STATION IS LOCATED ON THE HIGHEST POINT OF A HILL ABOUT 3.5 MILES NORTHEAST OF RODESSA 3.5 MILES WEST OF IDA AND ABOUT 0.5 OF A MILE SOUTH OF THE LOUISIANA-ARKANSAS STATE LINE. IT IS 21.0 FEET SOUTH OF THE CENTER OF A TRACK ROAD AND 4.0 FEET EAST OF A WITNESS POST. THE SURFACE STATION MARK HAD BEEN TILTED BY GRADING MACHINERY AND WAS PLUMBED IN OVER THE UNDERGROUND STATION MARK. IT PROJECTS 3 INCHES AND IS STAMPED SPEARMAN 1930 1950.

REFERENCE MARK NO. 1 IS LOCATED ON THE NORTHEAST SLOPE OF THE HILL ABOUT 5.0 FEET BELOW THE ELEVATION OF THE STATION. IT IS 210.0 FEET NORTH OF THE CENTER OF A TRACK ROAD. IT PROJECTS 4 INCHES AND IS STAMPED SPEARMAN NO 1 1930.

REFERENCE MARK NO. 3 IS ABOUT THE SAME ELEVATION AS THE STATION. IT IS 178.0 FEET SOUTH OF A TRACK ROAD. IT PROJECTS 5 INCHES AND IS STAMPED SPEARMAN NO 3 1950.

THE AZIMUTH MARK IS 19.0 FEET WEST OF THE CENTER OF A GRADED ROAD 2.0 FEET NORTH OF A FENCE CORNER AND 1.0 FOOT NORTH OF AN EAST-WEST FENCE AND 1.0 FOOT NORTH OF A WITNESS POST. IT PROJECTS 4 INCHES AND IS STAMPED SPEARMAN 1950.

TO REACH THE STATION FROM THE JUNCTION OF U.S. HIGHWAY NO. 71 AND STATE HIGHWAY NO. 991 IN IDA GO WESTERLY ON STATE HIGHWAY NO. 991 FOR 3.1 MILES TO A CROSSROAD TURN RIGHT AND GO NORTHERLY ON A DIRT ROAD FOR 0.85 MILE TO A FENCE CORNER ON THE LEFT AND THE AZIMUTH MARK ON THE LEFT AS DESCRIBED CONTINUE NORTHERLY ON DIRT ROAD FOR 0.2 MILE TO A FORK TAKE LEFT FORK FOR 0.15 MILE TURN LEFT AND GO 0.1 MILE TO A TRACK ROAD RIGHT TURN RIGHT ON TRACK ROAD AND GO 0.1 MILE TO THE TOP OF THE HILL AND THE STATION AS DESCRIBED.

The horizontal coordinates were established by GPS observations and adjusted by the National Geodetic Survey in September 1999.

The orthometric height was determined by differential leveling and adjusted in June 1991.

The X Y and Z were computed from the position and the ellipsoidal ht.

The Laplace correction was computed from USDV2009 derived deflections.

The ellipsoidal height was determined by GPS observations and is referenced to NAD 83.

The geoid height was determined by GEOID09.

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

The modeled gravity was interpolated from observed gravity values.

The orthometric height was determined by differential leveling and adjusted in June 1991.

The geoid height was determined by GEOID09.

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

The modeled gravity was interpolated from observed gravity values.

STATION DESCRIPTION

DESCRIBED BY COAST AND GEODETIC SURVEY 1950 (RLE) THE STATION IS LOCATED ABOUT 2-1/2 MILES NORTH AND 2.0 MILES WEST OF PLAIN DEALING AND 2.0 MILES WEST OF BOLINGER ON THE HIGHEST POINT OF A PROMINENT TIMBERED RIDGE ON THE NORTH SIDE OF AN EAST-WEST GRADED ROAD NEAR THE BOLINGER FIRE TOWER AND ON LAND OWNED BY MR. M.R. BOLINGER. IT IS 49 FEET NORTH OF THE CENTER OF THE ROAD AND 52 FEET EAST OF THE CENTER OF THE FIRE TOWER. IT IS STAMPED BOLINGER 1950 AND PROJECTS 5 INCHES.

REFERENCE MARK NO 1 IS SOUTHEAST OF THE STATION 48 FEET SOUTH OF THE CENTER OF EAST-WEST GRADED ROAD AND ON ABOUT THE SAME ELEVATION AS THE STATION MARK. IT IS STAMPED BOLINGER NO 1 1950 AND PROJECTS 4 INCHES.

REFERENCE MARK NO 2 IS SOUTHWEST OF THE STATION 33 FEET SOUTH OF THE CENTER OF EAST-WEST GRADED ROAD AND ON ABOUT THE SAME ELEVATION AS THE STATION MARK. IT IS STAMPED BOLINGER NO 2 1950 AND PROJECTS 4 INCHES.

THE DISTANCE BETWEEN R.M. NO 1 AND R.M. NO 2 IS 251.07 FEET.

THE AZIMUTH MARK IS ABOUT 0.45 MILE EAST OF THE STATION 10 FEET SOUTH OF THE CENTER OF EAST-WEST GRADED ROAD AND 2 FEET WEST OF WITNESS POST. IT IS STAMPED BOLINGER 1950 AND PROJECTS 2 INCHES.

TO REACH THE STATION FROM THE RAILROAD STATION IN PLAIN DEALING GO WEST FOR 0.2 MILE TURN RIGHT AND GO NORTH FOR 2.7 MILES TO SIDE ROAD LEFT TURN LEFT AND FOLLOW GRADED ROAD WESTERLY KEEPING STRAIGHT AHEAD AT ALL SIDE ROADS FOR 1.85 MILES TO THE AZIMUTH MARK ON THE SOUTH SIDE AS DESCRIBED CONTINUE WEST ON GRADED ROAD KEEPING STRAIGHT AHEAD AT ALL SIDE ROADS FOR 0.45 MILE TO THE BOLINGER FIRE TOWER ON THE RIGHT AND STATION JUST EAST AS DESCRIBED.

The horizontal coordinates were scaled from a topographic map and have an estimated accuracy of +/- 6 seconds.

The orthometric height was determined by differential leveling and adjusted in March 2001.

The geoid height was determined by GEOID09.

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

The modeled gravity was interpolated from observed gravity values.

The horizontal coordinates were scaled from a topographic map and have an estimated accuracy of +/- 6 seconds.

The orthometric height was determined by differential leveling and adjusted in June 1991.

The geoid height was determined by GEOID09.

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

The modeled gravity was interpolated from observed gravity values.
