 NK0285.This mark is at Iowa Fall Municipal Airport (IFA)
 NK0285
 NK0285.The horizontal coordinates were established by GPS observations
 NK0285.and adjusted by the National Geodetic Survey in June 2012.
 NK0285
 NK0285.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has 
 NK0285.been affixed to the stable North American tectonic plate. See 
 NK0285.www.ngs.noaa.gov/web/surveys/NA2011 for more information. 
 NK0285
 NK0285.The horizontal coordinates are valid at the epoch date displayed above
 NK0285.which is a decimal equivalence of Year/Month/Day.
 NK0285
 NK0285.The orthometric height was determined by differential leveling and
 NK0285.adjusted by the NATIONAL GEODETIC SURVEY
 NK0285.in June 1991.
 NK0285
 NK0285.Significant digits in the geoid height do not necessarily reflect accuracy.
 NK0285.GEOID18 height accuracy estimate available here.

 NK0285.Click photographs - Photos may exist for this station.
 NK0285
 NK0285.The X, Y, and Z were computed from the position and the ellipsoidal ht.
 NK0285
 NK0285.The Laplace correction was computed from DEFLEC18 derived deflections.
 NK0285
 NK0285.The ellipsoidal height was determined by GPS observations
 NK0285.and is referenced to NAD 83.
 NK0285
 NK0285.The dynamic height is computed by dividing the NAVD 88
 NK0285.geopotential number by the normal gravity value computed on the
 NK0285.Geodetic Reference System of 1980 (GRS 80) ellipsoid at 45
 NK0285.degrees latitude (g = 980.6199 gals.).
 NK0285
 NK0285.The modeled gravity was interpolated from observed gravity values.

 MH0207
 MH0207.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has 
 MH0207.been affixed to the stable North American tectonic plate. See 
 MH0207.www.ngs.noaa.gov/web/surveys/NA2011 for more information. 
 MH0207
 MH0207.The horizontal coordinates are valid at the epoch date displayed above
 MH0207.which is a decimal equivalence of Year/Month/Day.
 MH0207
 MH0207.No horizontal observational check was made to the station.
 MH0207
 MH0207.The orthometric height was determined by differential leveling and
 MH0207.adjusted by the NATIONAL GEODETIC SURVEY

 OP1149
 OP1149.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has 
 OP1149.been affixed to the stable North American tectonic plate. See 
 OP1149.www.ngs.noaa.gov/web/surveys/NA2011 for more information. 
 OP1149
 OP1149.The horizontal coordinates are valid at the epoch date displayed above
 OP1149.which is a decimal equivalence of Year/Month/Day.
 OP1149
 OP1149.The orthometric height was determined by GPS observations and a
 OP1149.high-resolution geoid model.
 OP1149
 OP1149.GPS derived orthometric heights for airport stations designated as
 OP1149.PACS or SACS are published to 2 decimal places.  This maintains
 OP1149.centimeter relative accuracy between the PACS and SACS.  It does
 OP1149.not indicate centimeter accuracy relative to other marks which are
 OP1149.part of the published vertical control network.

 NL0856
 NL0856'RECOVERY NOTE BY COAST AND GEODETIC SURVEY 1948 (MEW)
 NL0856'STATION WAS RECOVERED AS DESCRIBED AND ALL MARKS WERE FOUND
 NL0856'IN GOOD CONDITION.
 NL0856'
 NL0856'DUE TO ROAD CONSTRUCTION PLANNED BY THE SAC COUNTY HIGHWAY
 NL0856'DEPARTMENT DURING 1948 THE STATION MARK AND BOTH REFERENCE
 NL0856'MARKS WOULD HAVE BEEN DESTROYED.  AS A RESULT THE STATION MARK
 NL0856'WAS LOWERED TO A DEPTH WHERE THE SURFACE MARK WILL BE
 NL0856'APPROXIMATELY 12 INCHES BELOW THE SURFACE OF THE DITCH WHEN THE
 NL0856'NEW ROAD IS FINISHED.  STATION MARK WILL BE APPROXIMATELY 30
 NL0856'FEET WEST OF THE CENTERLINE OF NEW ROAD.  NO OTHER
 NL0856'MEASUREMENTS WERE TAKEN TO THE STATION AS ALL OBJECTS
 NL0856'WILL BE MOVED BECAUSE OF THE ROAD CONSTRUCTION.  STATION AND
 NL0856'UNDERGROUND MARKS ARE DESCRIBED.  THE NEW
 NL0856'MARKS WERE STAMPED ARNDT 1934.
 NL0856'
 NL0856'TWO NEW REFERENCE MARKS WERE ESTABLISHED AND THE OLD ONES
 NL0856'WERE DESTROYED.
 NL0856'
 NL0856'REFERENCE MARK NO. 3 IS 87.54 FEET NORTHEAST OF THE STATION,
 NL0856'APPROXIMATELY 42 FEET EAST OF THE CENTERLINE OF NEW ROAD
 NL0856'AND 2 FEET WEST OF THE EAST R.O.W. FENCE.  THE MARK PROJECTS 4

 NL0856'APPROXIMATELY 53 FEET EAST OF THE CENTERLINE OF NEW ROAD, 9
 NL0856'FEET EAST OF THE EAST R.O.W. FENCE AND 1 FOOT NORTH OF THE
 NL0856'NORTH DRIVEWAY FENCE TO MR. G.F. ARNDTS FARM HOUSE.  THE MARK
 NL0856'PROJECTS 4 INCHES AND THE DISC IS STAMPED ARNDT NO 4 1934.
 NL0856'
 NL0856'THE DIRECTIONS TO THE NEW REFERENCE MARKS WERE OBTAINED BY
 NL0856'INITIALING ON REFERENCE MARK NO. 1 AND MEASURING THE ANGLES
 NL0856'TO THE NEW REFERENCE MARKS AND REFERENCE MARK NO. 2.  THE
 NL0856'ANGLE MEASURED BETWEEN THE OLD REFERENCE MARKS NO. 1 AND NO. 2
 NL0856'CHECKED THE ANGLE MEASURED IN 1934.  THE AZIMUTH MARK WAS NOT
 NL0856'USED AS THE INITIAL AS IT WAS NOT VISIBLE FROM THE GROUND.
 NL0856'A GROUP OF TREES NEAR THE STATION OBSTRUCTED THE LINE OF
 NL0856'SIGHT.  THIS GROUP OF TREES WILL BE REMOVED BY THE NEW ROAD
 NL0856'CONSTRUCTION AND THE AZIMUTH MARK WILL BE VISIBLE FROM THE
 NL0856'GROUND.

 OO0914'THE SURFACE STATION MARK, REFERENCE MARKS 1 AND 2 WERE RECOVERED IN
 OO0914'GOOD CONDITION.  THE AZIMUTH MARK WAS FOUND TILTED AND THE DISK WAS
 OO0914'SALVAGE.  AN AZIMUTH MARK 2 WAS ESTABLISHED.  THE DIRECTION TO
 OO0914'REFERENCE MARK 1 AGREED WITH 1934 DATA BUT THE DISTANCE WAS 3 FT (0.9
 OO0914'M) LONGER.  THE DIRECTION TO REFERENCE MARK 2 FAILED TO AGREE BUT THE
 OO0914'DISTANCE AGREED.  A FAVORABLE CHECK ANGLE WAS OBTAINED BETWEEN TWO OLD
 OO0914'DISTANT OBJECTS, THEREFORE, THE UNDERGROUND MARK WAS NOT INSPECTED.  A
 OO0914'NEW DESCRIPTION IS REQUIRED.
 OO0914'THE STATION IS ABOUT 6 MILES (9.7 KM) EAST OF NEW HAMPTON, 2-1/2 MILES

 NL0708'RECOVERY NOTE BY NATIONAL GEODETIC SURVEY 1978 (CLN)
 NL0708'STATION UNDERGROUND MARK, REFERENCE MARKS 1, 3 AND 4 WERE RECOVERED IN
 NL0708'GOOD CONDITION.  THE SURFACE STATION MARK HAD BEEN DISLODGED BY FARM
 NL0708'OPERATIONS.  A NEW SURFACE MARK WAS ESTABLISHED HOLDING THE EXACT
 NL0708'POSITION OF THE UNDERGROUND MARK AFTER THAT MARKS POSITION WAS
 NL0708'CHECKED FROM THE REFERENCE MARKS.  THE NEW SURFACE MARK WAS LEFT 14
 NL0708'INCHES BELOW THE GROUND SURFACE TO ALLOW FOR FARMING OPERATIONS.  THE
 NL0708'DISTANCE TO REFERENCE MARK 1 WAS 0.002 METER LONGER AND THE DISTANCE
 NL0708'TO REFERENCE MARK 3 WAS ALSO 0.002 METER LONGER WHILE THE DISTANCE
 NL0708'BETWEEN THE MARKS WAS ALSO 0.002 METER LONGER THAN 1972 DATA.  THE
 NL0708'DIRECTION FROM REFERENCE MARK 4 TO REFERENCE MARK 1 WAS 26 SECONDS
 NL0708'LARGER AND TO REFERENCE MARK 3 WAS 12 SECONDS LARGER THAN 1972 DATA.

 MH0466'RECOVERY NOTE BY COAST AND GEODETIC SURVEY 1969 (JWC)
 MH0466'THE STATION MARK WAS RECOVERED AND FOUND TO BE IN GOOD
 MH0466'CONDITION.  REFERENCE MARKS 1, 2 AND 3 WERE DESTROYED AS DESCRIBED
 MH0466'IN 1963.  DUE TO THE STATION BEING IN A CULTIVATED FIELD OF CORN,
 MH0466'PERMISSION COULD NOT BE OBTAINED TO ERECT A STEEL TOWER OVER
 MH0466'IT.  REFERENCE MARKS 4 AND 5 WERE ESTABLISHED AT THIS TIME AND
 MH0466'REFERENCE MARK 5 WAS OCCUPIED.  THE STATION MARK WAS NOT
 MH0466'OCCUPIED AND REFERENCE MARK 4 WAS NOT MEASURED AT THIS TIME
 MH0466'BECAUSE OF THE AMOUNT OF CROP DAMAGE INVOLVED.  A GEODIMETER
 MH0466'MEASUREMENT WAS MADE FROM THE STATION TO THE TOP OF THE TOWER
 MH0466'OVER REFERENCE MARK 5, THE DISTANCE REDUCED TO SEA LEVEL
 MH0466'BEING 144.552 METERS OR 474.251 FEET.

 DP1227.The coordinates were established by GPS observations
 DP1227.and adjusted by the National Geodetic Survey in April 2025.
 DP1227
 DP1227.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has 
 DP1227.been affixed to the stable North American Tectonic Plate. 
 DP1227
 DP1227.The coordinates are valid at the epoch date displayed above
 DP1227.which is a decimal equivalence of Year/Month/Day.
 DP1227
 DP1227.NGS completed the third reprocessing of daily RINEX data from 1996 to 2022
 DP1227.for all stations in the NOAA CORS Network (NCN).  The reprocessed solution,
 DP1227.known as the Multi-Year CORS Solution 3 (MYCS3), is aligned with the
 DP1227.ITFR2020 global frame, epoch 2020.00.  The resulting MYCS3 coordinates
 DP1227.were then transformed to NAD83(2011/MA11/PA11), maintaining the currently
 DP1227.published epoch of 2010.00.

 MJ1426
 MJ1426.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has 
 MJ1426.been affixed to the stable North American tectonic plate. See 
 MJ1426.www.ngs.noaa.gov/web/surveys/NA2011 for more information. 
 MJ1426
 MJ1426.The horizontal coordinates are valid at the epoch date displayed above
 MJ1426.which is a decimal equivalence of Year/Month/Day.
 MJ1426
 MJ1426.The orthometric height was determined by GPS observations and a
 MJ1426.high-resolution geoid model.
 MJ1426
 MJ1426.GPS derived orthometric heights for airport stations designated as
 MJ1426.PACS or SACS are published to 2 decimal places.  This maintains
 MJ1426.centimeter relative accuracy between the PACS and SACS.  It does
 MJ1426.not indicate centimeter accuracy relative to other marks which are
 MJ1426.part of the published vertical control network.

 AE2133.The horizontal coordinates are valid at the epoch date displayed above
 AE2133.which is a decimal equivalence of Year/Month/Day.
 AE2133
 AE2133.The orthometric height was determined by GPS observations and a
 AE2133.high-resolution geoid model.
 AE2133
 AE2133.GPS derived orthometric heights for airport stations designated as
 AE2133.PACS or SACS are published to 2 decimal places.  This maintains
 AE2133.centimeter relative accuracy between the PACS and SACS.  It does
 AE2133.not indicate centimeter accuracy relative to other marks which are
 AE2133.part of the published vertical control network.

 MJ1134'DESCRIBED BY COAST AND GEODETIC SURVEY 1934 (CAS)
 MJ1134'THIS STATION IS THE LOW SQUAT BLACK MUNICIPAL TANK IN THE
 MJ1134'VILLAGE OF DEDHAM, IOWA.  IT IS LOCATED ON THE E SIDE OF TOWN
 MJ1134'ON A PROMINENCE SOMEWHAT HIGHER THAN THE REST OF THE VILLAGE.
 MJ1134'IT IS ABOUT 120 YARDS E OF STATE HIGHWAY 46 FROM A POINT 110
 MJ1134'YARDS S OF THE POINT WHERE HIGHWAY 46 TURNS FROM E TO S IN
 MJ1134'DEDHAM.  IT IS IN SECTION 20, T 82 N, R 34 W.  IT WAS
 MJ1134'ERECTED IN 1921.  IT IS NOT VERY PROMINENT, BEING OBSCURED
 MJ1134'ON THE W AND S BY HIGH TREES.
 MJ1134'
 MJ1134'THE TANK HAS FOUR TRUSS-WORK LEGS 40 FEET HIGH.  THE OVAL
 MJ1134'SECTION EXTENDS DOWNWARD ABOUT 15 FEET, FROM WHICH A FEED PIPE
 MJ1134'JACKET EXTENDS TO THE GROUND.  THE VERTICAL SECTION IS ABOUT
 MJ1134'15 FEET HIGH.  THE LEGS, OVAL SECTION, VERTICAL SECTION,
 MJ1134'AND FEEDPIPE JACKET ARE BLACK IN COLOR.  THE FLAT CONICAL
 MJ1134'ROOF IS WHITE, ABOUT 2 FEET HIGH AND HAS A WHITE BALL AT ITS
 MJ1134'APEX.  THE TOTAL HEIGHT IS ABOUT 58 FEET.

 MJ1177
 MJ1177'DESCRIBED BY NATIONAL GEODETIC SURVEY 1981 (CLN)
 MJ1177'THE STATION IS LOCATED ABOUT 2 MILES NORTH AND 4 MILES WEST OF
 MJ1177'DEFIANCE, ON THE RIGHT-OF-WAY OF COUNTY ROUTE R.  IT IS 48 FEET SOUTH
 MJ1177'OF THE CENTER OF WHERE COUNTY ROUTE R CROSSES A NORTH-SOUTH OIL TOP
 MJ1177'ROAD, 8 FEET WEST-NORTHWEST OF A TELEPHONE POLE WITH A TRIANGLE BLAZE,
 MJ1177'6 FEET EAST-NORTHEAST OF A FENCE CORNER, AND 4 FEET NORTH OF A FENCE.
 MJ1177'
 MJ1177'THE SURFACE STATION MARK AND REFERENCE MARK 2 WERE FOUND BUT HAD
 MJ1177'OBVIOUSLY BEEN DISTURBED.  REFERENCE MARK 1 WAS FOUND DESTROYED.  THE
 MJ1177'AZIMUTH MARK WAS FOUND IN APPARENT GOOD CONDITION, HOWEVER, THE
 MJ1177'DIRECTION TO THE MARK WAS 10 DEGREES SMALLER THAN 1950 DATA.  A CHECK
 MJ1177'OF 6.1 SECONDS LARGER WAS OBTAINED BETWEEN THE WESTPHALIA ST BONIFACE
 MJ1177'CHURCH AND THE EARLING CATHOLIC CHURCH.  STATION MARK, REFERENCE MARK
 MJ1177'1 AND THE AZIMUTH MARK WERE IN THE WAY OF ROAD CONSTRUCTION,
 MJ1177'THEREFORE, STATION--DEFIANCE 2--, REFERENCE MARKS 3, 4 AND ANOTHER
 MJ1177'AZIMUTH MARK WERE ESTABLISHED.  REFERENCE MARK 2, ALTHOUGH VERY POOR,
 MJ1177'IS NOW A SHELBY COUNTY BENCH MARK AND WAS LEFT IN PLACE.  THE
 MJ1177'UNDERGROUND WAS ALSO LEFT IN PLACE BUT WILL PROBABLY BE DESTROYED.
 MJ1177'ALL 1981 OBSERVATIONS WERE TAKEN FROM THE UNDERGROUND MARK.  DISKS
 MJ1177'WERE SALVAGED FROM THE OLD SURFACE MARK, REFERENCE MARK 1 AND THE
 MJ1177'AZIMUTH MARK.

 MJ1177
 MJ1177'RECOVERY NOTE BY NATIONAL GEODETIC SURVEY 1982 (CLN)
 MJ1177'THE UNDERGROUND STATION MARK, DEFIANCE 2 AND DEFIANCE 2 AZ MK WERE
 MJ1177'RECOVERED IN GOOD CONDITION.  REFERENCE MARK 2 WAS RECOVERED IN POOR
 MJ1177'CONDITION AND WAS NOT USED.  SHELBY COUNTY USES THE MARK AS A BENCH
 MJ1177'MARK, THEREFORE IT WAS LEFT IN PLACE.  DUE TO GRADING CHANGES, THE NEW
 MJ1177'STATION WAS SITUATED IN A CULTIVATED FIELD, INSTEAD OF ON COUNTY ROAD
 MJ1177'RIGHT-OF-WAY.  THIS WAS NOT AGREEABLE WITH THE PROPERTY OWNER AND HE
 MJ1177'REQUESTED THAT DEFIANCE 2 AND DEFIANCE 2 RM 3 BE REMOVED.  THE
 MJ1177'POSITION OF THE ORIGINAL UNDERGROUND MARK WAS HELD AND A NEW
 MJ1177'UNDERGROUND MARK AND A NEW SURFACE MARK WERE THEN ESTABLISHED, AS THE
 MJ1177'ORIGINAL UNDERGROUND MARK WAS FOUND ONLY 0.15 M (0.49 FT) BELOW THE
 MJ1177'SURFACE.  REFERENCE MARK 5 WAS ALSO ESTABLISHED AND DEFIANCE 2
 MJ1177'REFERENCE MARK 4 NOW SERVES THE ORIGINAL STATION.  THE ARROW ON THIS
 MJ1177'MARK POINTS TOWARD DEFIANCE 2 UNDERGROUND MARK, WHICH WAS LEFT IN
 MJ1177'PLACE.  SATISFACTORY CHECKS ANGLES TO DISTANT OBJECTS WERE OBTAINED.

 MH0802'A 6-HOUR GPS SESSION OVER THE DISK FOUND EXCESSIVE MULTIPATH AND GAVE
 MH0802'A LOOSE RESULT SUGGESTING THE MARK WAS SIGNIFICANTLY HIGHER THAN THE
 MH0802'LEVELED NAVD88 VALUE OF 261.06 M (856.5 FT).  A 4.6-HOUR OPUS-S
 MH0802'SESSION AT AN OFFSET POINT UNDER CLEAR SKY AND LEVELED TO THE MARK
 MH0802'GAVE A NAD83 ELLIPSOIDAL HEIGHT OF 229.021 M (751.4 FT) AND USING
 MH0802'GEOID12B ORTHO=261.311 M.
 MH0802'
 MH0802'IF THE RESET CALCULATION WAS IN ERROR BY EXACTLY 1.00 FT (0.305 M),
 MH0802'THE DIFFERENCE (GPS-GEOID12B)-LEVELED WOULD BE TYPICAL FOR THE AREA.

 NL0663'RECOVERY NOTE BY US ARMY CORPS OF ENGINEERS 1937
 NL0663'FOUND, MO. R.C. STATION KENNEBEC DIRECTLY UNDER YOUR STATION
 NL0663'HATHOWAY.  IT IS A STONE 18 IN X 18 IN X 3 IN WITH A COPPER
 NL0663'BOLT SET IN CENTER OF STONE.  THERE IS NO INDICATION THAT
 NL0663'THE STONE OF THE ORIGINAL STATION KENNEBEC HAS BEEN DISTURBED.
 NL0663'THE ORIGNAL PIPE PLACED OVER THIS STONE HAS BEEN REMOVED AND
 NL0663'WAS FOUND AT THE FOOT OF THE HILL.  THE CONCRETE OF YOUR
 NL0663'MONUMENT FOR STATION HATHOWAY EXTENDS DOWN TO THE FACE OF THE
 NL0663'STONE MARKING THE POSITION OF THE MO. R.C. STATION
 NL0663'KENNEBEC.  IT IS NOT POSSIBLE TO LOCATED THE MARK ON THIS
 NL0663'STONE WITHOUT CHIPPING AWAY THE CONCRETE AND DISTURBING
 NL0663'YOUR MONUMENT.  HOWEVER, BY MEASURMENTS TO CORNERS OF THE STONE,
 NL0663'IT IS APPARENT THAT THE STATION HATHOWAY IS WITHIN 0.1
 NL0663'FOOT OF A POINT DIRECTLY OVER THE CENTER OF THE STONE OF
 NL0663'THE ORIGINAL STATION KENNEBEC.  THE ORIGINAL POINT MAY NOT BE
 NL0663'AT THE EXACT CENTER OF THE STONE.
 NL0663'
 NL0663'STATION IS IN GOOD CONDITION AND THERE IS NO CHANGE IN THE
 NL0663'ORIGINAL DESCRIPTION EXCEPT THAT NO REFERENCE WAS MADE TO

 NL0663'THE STATION WAS RECOVERED AND ALL MARKS FOUND IN GOOD CONDITION.
 NL0663'A NEW DESCRIPTION FOLLOWS.
 NL0663'
 NL0663'THE STATION IS LOCATED ABOUT 5.5 MILES E AND 3.0 MILES N
 NL0663'OF THE VILLAGE OF ONAWA ON THE OLD HATHOWAY FARM WHICH IS
 NL0663'NOW VACANT.  NOTHING IS LEFT OF THE OLD HATHOWAY HOME SITE
 NL0663'EXCEPT A LONE WINDMILL TOWER.  THE STATION IS ABOUT 300
 NL0663'YARDS E OF THE OLD TOWER ON THE HIGHEST POINT OF THE BLUFF.
 NL0663'
 NL0663'THIS STATION WAS RECOVERED IN AN EFFORT TO TRAVERSE TO MO.
 NL0663'R.C. STATION KENNEBEC AND A THOROUGH SEARCH WAS MADE WITHOUT
 NL0663'RESULTS.  A BENCH WAS ESTABLISHED OVER STATION HATHOWAY AND
 NL0663'A POINT SET DIRECTLY OVER THE SURFACE MARK, THEN THE SURFACE
 NL0663'MARK WAS REMOVED IN ORDER TO INVESTIGATE THE SUBSURFACE
 NL0663'MARK.
 NL0663'
 NL0663'THE SUBSURFACE MARK WAS FOUND TO BE A BRONZE STATION DISK
 NL0663'SET IN THE CENTER OF AN 18-INCH SQUARE LIMESTONE BLOCK AND
 NL0663'THE DISK WAS STAMPED HATHOWAY 1934.  THIS SUBSURFACE MARK
 NL0663'WAS FOUND TO BE PLUMB WITH THE SURFACE MARK.  THE SURFACE
 NL0663'MARK WAS REESTABLISHED IN THE EXACT LOCATION AS ORIGINALLY
 NL0663'FOUND.
 NL0663'
 NL0663'MR. LAURENCE H. HART, CHIEF OF SURVEYS, U.S. ENGINEERS OFFICE
 NL0663'OF ONAWA, IOWA WAS CONTACTED AND THE FOLLOWING DATA WAS
 NL0663'OBTAINED--IN JUNE 1937 MR. HART VISITED STATION HATHOWAY
 NL0663'AND FOUND THE MO. R.C. KENNEBEC STATION SURFACE MARK HAD
 NL0663'BEEN REMOVED AND WAS FOUND ON THE SLOPE ON THE W SIDE OF
 NL0663'THE HILL UPON WHICH THE STATION IS LOCATED.

 DM2686.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has 
 DM2686.been affixed to the stable North American Tectonic Plate. 
 DM2686
 DM2686.The coordinates are valid at the epoch date displayed above
 DM2686.which is a decimal equivalence of Year/Month/Day.
 DM2686
 DM2686.NGS completed the third reprocessing of daily RINEX data from 1996 to 2022
 DM2686.for all stations in the NOAA CORS Network (NCN).  The reprocessed solution,
 DM2686.known as the Multi-Year CORS Solution 3 (MYCS3), is aligned with the
 DM2686.ITFR2020 global frame, epoch 2020.00.  The resulting MYCS3 coordinates
 DM2686.were then transformed to NAD83(2011/MA11/PA11), maintaining the currently
 DM2686.published epoch of 2010.00.
 DM2686
 DM2686.Additional information on MYCS is available at:
 DM2686.https://geodesy.noaa.gov/CORS/index.shtml
 DM2686
 DM2686.The orthometric height was determined by GPS observations and a
 DM2686.high-resolution geoid model using precise GPS observation and
 DM2686.processing techniques.

 DP1316.NGS completed the third reprocessing of daily RINEX data from 1996 to 2022
 DP1316.for all stations in the NOAA CORS Network (NCN).  The reprocessed solution,
 DP1316.known as the Multi-Year CORS Solution 3 (MYCS3), is aligned with the
 DP1316.ITFR2020 global frame, epoch 2020.00.  The resulting MYCS3 coordinates
 DP1316.were then transformed to NAD83(2011/MA11/PA11), maintaining the currently
 DP1316.published epoch of 2010.00.

 DP1237.NGS completed the third reprocessing of daily RINEX data from 1996 to 2022
 DP1237.for all stations in the NOAA CORS Network (NCN).  The reprocessed solution,
 DP1237.known as the Multi-Year CORS Solution 3 (MYCS3), is aligned with the
 DP1237.ITFR2020 global frame, epoch 2020.00.  The resulting MYCS3 coordinates
 DP1237.were then transformed to NAD83(2011/MA11/PA11), maintaining the currently
 DP1237.published epoch of 2010.00.

 DP1247.NGS completed the third reprocessing of daily RINEX data from 1996 to 2022
 DP1247.for all stations in the NOAA CORS Network (NCN).  The reprocessed solution,
 DP1247.known as the Multi-Year CORS Solution 3 (MYCS3), is aligned with the
 DP1247.ITFR2020 global frame, epoch 2020.00.  The resulting MYCS3 coordinates
 DP1247.were then transformed to NAD83(2011/MA11/PA11), maintaining the currently
 DP1247.published epoch of 2010.00.

 OO1635.The horizontal coordinates were established by GPS observations
 OO1635.and adjusted by the National Geodetic Survey in June 2012.
 OO1635
 OO1635.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has 
 OO1635.been affixed to the stable North American tectonic plate. See 
 OO1635.www.ngs.noaa.gov/web/surveys/NA2011 for more information. 
 OO1635
 OO1635.The horizontal coordinates are valid at the epoch date displayed above
 OO1635.which is a decimal equivalence of Year/Month/Day.
 OO1635
 OO1635.The orthometric height was determined by differential leveling and
 OO1635.adjusted by the NATIONAL GEODETIC SURVEY
 OO1635.in November 1998.

 DL3589.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has 
 DL3589.been affixed to the stable North American Tectonic Plate. 
 DL3589
 DL3589.The coordinates are valid at the epoch date displayed above
 DL3589.which is a decimal equivalence of Year/Month/Day.
 DL3589
 DL3589.NGS completed the third reprocessing of daily RINEX data from 1996 to 2022
 DL3589.for all stations in the NOAA CORS Network (NCN).  The reprocessed solution,
 DL3589.known as the Multi-Year CORS Solution 3 (MYCS3), is aligned with the
 DL3589.ITFR2020 global frame, epoch 2020.00.  The resulting MYCS3 coordinates
 DL3589.were then transformed to NAD83(2011/MA11/PA11), maintaining the currently
 DL3589.published epoch of 2010.00.
 DL3589
 DL3589.Additional information on MYCS is available at:
 DL3589.https://geodesy.noaa.gov/CORS/index.shtml
 DL3589
 DL3589.The orthometric height was determined by GPS observations and a
 DL3589.high-resolution geoid model using precise GPS observation and
 DL3589.processing techniques.

 AE9184.This is a reference station for the NORTH LIBERTY
 AE9184.National Continuously Operating Reference Station (NLIB).
 AE9184
 AE9184.The horizontal coordinates were established by GPS observations
 AE9184.and adjusted by the National Geodetic Survey in June 2012.
 AE9184
 AE9184.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has 
 AE9184.been affixed to the stable North American tectonic plate. See 
 AE9184.www.ngs.noaa.gov/web/surveys/NA2011 for more information. 
 AE9184
 AE9184.The horizontal coordinates are valid at the epoch date displayed above
 AE9184.which is a decimal equivalence of Year/Month/Day.
 AE9184
 AE9184.The orthometric height was determined by differential leveling and
 AE9184.adjusted by the NATIONAL GEODETIC SURVEY
 AE9184.in July 2002.
 AE9184
 AE9184.Significant digits in the geoid height do not necessarily reflect accuracy.
 AE9184.GEOID18 height accuracy estimate available here.
 AE9184
 AE9184.Click photographs - Photos may exist for this station.
 AE9184
 AE9184.The X, Y, and Z were computed from the position and the ellipsoidal ht.
 AE9184
 AE9184.The Laplace correction was computed from DEFLEC18 derived deflections.
 AE9184
 AE9184.The ellipsoidal height was determined by GPS observations
 AE9184.and is referenced to NAD 83.
 AE9184

 MG0916.This is a reference station for the NORTH LIBERTY
 MG0916.National Continuously Operating Reference Station (NLIB).
 MG0916
 MG0916.The horizontal coordinates were established by GPS observations
 MG0916.and adjusted by the National Geodetic Survey in June 2012.
 MG0916
 MG0916.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has 
 MG0916.been affixed to the stable North American tectonic plate. See 
 MG0916.www.ngs.noaa.gov/web/surveys/NA2011 for more information. 
 MG0916
 MG0916.The horizontal coordinates are valid at the epoch date displayed above
 MG0916.which is a decimal equivalence of Year/Month/Day.
 MG0916
 MG0916.The orthometric height was determined by differential leveling and
 MG0916.adjusted by the NATIONAL GEODETIC SURVEY
 MG0916.in July 2002.
 MG0916
 MG0916.Significant digits in the geoid height do not necessarily reflect accuracy.

 MG0916
 MG0916.The X, Y, and Z were computed from the position and the ellipsoidal ht.
 MG0916
 MG0916.The Laplace correction was computed from DEFLEC18 derived deflections.
 MG0916
 MG0916.The ellipsoidal height was determined by GPS observations
 MG0916.and is referenced to NAD 83.
 MG0916
 MG0916.The dynamic height is computed by dividing the NAVD 88
 MG0916.geopotential number by the normal gravity value computed on the
 MG0916.Geodetic Reference System of 1980 (GRS 80) ellipsoid at 45
 MG0916.degrees latitude (g = 980.6199 gals.).
 MG0916
 MG0916.The modeled gravity was interpolated from observed gravity values.

 AF9523.NGS completed the third reprocessing of daily RINEX data from 1996 to 2022
 AF9523.for all stations in the NOAA CORS Network (NCN).  The reprocessed solution,
 AF9523.known as the Multi-Year CORS Solution 3 (MYCS3), is aligned with the
 AF9523.ITFR2020 global frame, epoch 2020.00.  The resulting MYCS3 coordinates
 AF9523.were then transformed to NAD83(2011/MA11/PA11), maintaining the currently
 AF9523.published epoch of 2010.00.

 AF9524.NGS completed the third reprocessing of daily RINEX data from 1996 to 2022
 AF9524.for all stations in the NOAA CORS Network (NCN).  The reprocessed solution,
 AF9524.known as the Multi-Year CORS Solution 3 (MYCS3), is aligned with the
 AF9524.ITFR2020 global frame, epoch 2020.00.  The resulting MYCS3 coordinates
 AF9524.were then transformed to NAD83(2011/MA11/PA11), maintaining the currently
 AF9524.published epoch of 2010.00.

 AE9293.This is a reference station for the OMAHA 1
 AE9293.National Continuously Operating Reference Station (OMH1).
 AE9293
 AE9293.The horizontal coordinates were established by GPS observations
 AE9293.and adjusted by the National Geodetic Survey in June 2012.
 AE9293
 AE9293.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has 
 AE9293.been affixed to the stable North American tectonic plate. See 
 AE9293.www.ngs.noaa.gov/web/surveys/NA2011 for more information. 
 AE9293
 AE9293.The horizontal coordinates are valid at the epoch date displayed above
 AE9293.which is a decimal equivalence of Year/Month/Day.
 AE9293
 AE9293.The orthometric height was determined by differential leveling and
 AE9293.adjusted by the NATIONAL GEODETIC SURVEY
 AE9293.in July 2002.

 AJ8304.The horizontal coordinates were established by GPS observations
 AJ8304.and adjusted by the National Geodetic Survey in June 2012.
 AJ8304
 AJ8304.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has 
 AJ8304.been affixed to the stable North American tectonic plate. See 
 AJ8304.www.ngs.noaa.gov/web/surveys/NA2011 for more information. 
 AJ8304
 AJ8304.The horizontal coordinates are valid at the epoch date displayed above
 AJ8304.which is a decimal equivalence of Year/Month/Day.
 AJ8304
 AJ8304.The orthometric height was determined by GPS observations and a
 AJ8304.high-resolution geoid model.
 AJ8304
 AJ8304.GPS derived orthometric heights for airport stations designated as
 AJ8304.PACS or SACS are published to 2 decimal places.  This maintains
 AJ8304.centimeter relative accuracy between the PACS and SACS.  It does
 AJ8304.not indicate centimeter accuracy relative to other marks which are
 AJ8304.part of the published vertical control network.
 AJ8304
 AJ8304.Significant digits in the geoid height do not necessarily reflect accuracy.

 MH0654'RECOVERY NOTE BY COAST AND GEODETIC SURVEY 1958 (REW)
 MH0654'THE STATION MARK AND REFERENCE MARK 2 WERE RECOVERED AND FOUND
 MH0654'TO BE IN GOOD CONDITION.  A ROUGH DISTANCE CHECK WAS MADE FROM
 MH0654'REFERENCE MARK 2 TO THE STATION TO ENABLE THE RECOVERY OF
 MH0654'THE STATION MARK, WHICH WAS EASILY FOUND.  REFERENCE MARK 1
 MH0654'WAS DESTROYED DURING ROAD IMPROVEMENTS.  THE DISK WAS REMOVED
 MH0654'FROM THE POST AND BROUGHT IN.  AN INSTRUMENT SET UP WAS
 MH0654'NOT MADE SO THE DIRECTION TO REFERENCE MARK 2 WAS NOT VERIFIED.
 MH0654'THE OLD ROUTE TO THE STATION IS NOW OBSOLETE AND A NEW ONE
 MH0654'FOLLOWS.

 MH0654'RECOVERY NOTE BY NATIONAL GEODETIC SURVEY 1979 (CLN)
 MH0654'THE STATION SIGHT WAS VISITED BUT THE FIELD WAS STILL IN CROPS AND THE
 MH0654'PROPERTY OWNER, MR. CHARLES CRAIG, COULD NOT BE LOCATED.  REFERENCE
 MH0654'MARK 2 WAS SEARCHED FOR BUT NOT FOUND.  THE STATE SURVEY TRAVERSE

 NL0877'RECOVERY NOTE BY COAST AND GEODETIC SURVEY 1952 (RLP)
 NL0877'THIS STATION WAS RECOVERED AS DESCRIBED, AND ALL MARKS WERE
 NL0877'FOUND IN GOOD CONDITION, EXCEPT THE AZIMUTH MARK WHICH WAS
 NL0877'DESTROYED WHEN STATE HIGHWAY 17 WAS REBUILT IN ABOUT 1937

 NL0877'AZIMUTH MARK FROM THE REFERENCE MARKS, AND A THOROUGH SEARCH
 NL0877'WAS MADE ON BOTH SIDES OF HIGHWAY, BUT NO EVIDENCE COULD
 NL0877'BE FOUND.  AS ORIGINALLY DESCRIBED, THE MARK WOULD BE IN THE
 NL0877'MIDDLE OF THE DITCH, AND, THEREFORE, SHOULD BE LISTED AS
 NL0877'DESTROYED.

 AE9311
 AE9311.The dynamic height is computed by dividing the NAVD 88
 AE9311.geopotential number by the normal gravity value computed on the
 AE9311.Geodetic Reference System of 1980 (GRS 80) ellipsoid at 45
 AE9311.degrees latitude (g = 980.6199 gals.).
 AE9311
 AE9311.The modeled gravity was interpolated from observed gravity values.

 DI8416.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has 
 DI8416.been affixed to the stable North American Tectonic Plate. 
 DI8416
 DI8416.The coordinates are valid at the epoch date displayed above
 DI8416.which is a decimal equivalence of Year/Month/Day.

 DI8416.NGS completed the third reprocessing of daily RINEX data from 1996 to 2022
 DI8416.for all stations in the NOAA CORS Network (NCN).  The reprocessed solution,
 DI8416.known as the Multi-Year CORS Solution 3 (MYCS3), is aligned with the
 DI8416.ITFR2020 global frame, epoch 2020.00.  The resulting MYCS3 coordinates
 DI8416.were then transformed to NAD83(2011/MA11/PA11), maintaining the currently
 DI8416.published epoch of 2010.00.

 LF1496.The horizontal coordinates were established by GPS observations
 LF1496.and adjusted by the National Geodetic Survey in June 2012.
 LF1496
 LF1496.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has 
 LF1496.been affixed to the stable North American tectonic plate. See 
 LF1496.www.ngs.noaa.gov/web/surveys/NA2011 for more information. 
 LF1496
 LF1496.The horizontal coordinates are valid at the epoch date displayed above
 LF1496.which is a decimal equivalence of Year/Month/Day.
 LF1496
 LF1496.The orthometric height was determined by GPS observations and a
 LF1496.high-resolution geoid model.
 LF1496
 LF1496.GPS derived orthometric heights for airport stations designated as
 LF1496.PACS or SACS are published to 2 decimal places.  This maintains
 LF1496.centimeter relative accuracy between the PACS and SACS.  It does
 LF1496.not indicate centimeter accuracy relative to other marks which are
 LF1496.part of the published vertical control network.

 NM0113.The horizontal coordinates were established by GPS observations
 NM0113.and adjusted by the National Geodetic Survey in June 2012.
 NM0113
 NM0113.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has 
 NM0113.been affixed to the stable North American tectonic plate. See 
 NM0113.www.ngs.noaa.gov/web/surveys/NA2011 for more information. 
 NM0113
 NM0113.The horizontal coordinates are valid at the epoch date displayed above
 NM0113.which is a decimal equivalence of Year/Month/Day.
 NM0113
 NM0113.The orthometric height was determined by differential leveling and
 NM0113.adjusted by the NATIONAL GEODETIC SURVEY
 NM0113.in June 1991.
 NM0113
 NM0113.Significant digits in the geoid height do not necessarily reflect accuracy.

 NM0113.The X, Y, and Z were computed from the position and the ellipsoidal ht.
 NM0113
 NM0113.The Laplace correction was computed from DEFLEC18 derived deflections.
 NM0113
 NM0113.The ellipsoidal height was determined by GPS observations
 NM0113.and is referenced to NAD 83.
 NM0113
 NM0113.The dynamic height is computed by dividing the NAVD 88
 NM0113.geopotential number by the normal gravity value computed on the
 NM0113.Geodetic Reference System of 1980 (GRS 80) ellipsoid at 45
 NM0113.degrees latitude (g = 980.6199 gals.).

 MJ1109'RECOVERY NOTE BY COAST AND GEODETIC SURVEY 1960 (FAR)
 MJ1109'ALL THE MARKS HAVE BEEN DESTROYED WHEN STATE HIGHWAY 148 WAS
 MJ1109'REBUILT IN ABOUT 1949.  ONE CONCRETE BLOCK WAS FOUND ALONG
 MJ1109'THE HIGHWAY RIGHT-OF-WAY NEAR THE SITE OF THE STATION.  THE
 MJ1109'DISK HAD BEEN REMOVED.  ADDITIONAL RIGHT-OF-WAY WAS SECURED WHEN
 MJ1109'THE HIGHWAY WAS REBUILT ACCORDING TO THE ADJOINING LANDOWNERS.
 MJ1109'THERE IS A TWELVE TO FIFTEEN FOOT CUT IN THE AREA OF THE
 MJ1109'STATION AND USING THE REFERENCES TO LOCAL OBJECTS, IT IS
 MJ1109'DOUBTFUL IF ANY MARKS REMAIN, INCLUDING THE UNDERGROUND MARK
 MJ1109'FOR THE STATION.  ABOUT TWO HOURS WAS SPENT PROBING FOR THE
 MJ1109'UNDERGROUND STATION MARK.  BUT NO EVIDENCE WAS FOUND.  IT IS
 MJ1109'BELIEVED THAT THIS STATION SHOULD BE LISTED AS COMPLETELY
 MJ1109'DESTROYED.

 NL0937
 NL0937.The horizontal coordinates were established by GPS observations
 NL0937.and adjusted by the National Geodetic Survey in June 2012.
 NL0937
 NL0937.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has 
 NL0937.been affixed to the stable North American tectonic plate. See 
 NL0937.www.ngs.noaa.gov/web/surveys/NA2011 for more information. 
 NL0937
 NL0937.The horizontal coordinates are valid at the epoch date displayed above
 NL0937.which is a decimal equivalence of Year/Month/Day.
 NL0937
 NL0937.The orthometric height was determined by GPS observations and a
 NL0937.high-resolution geoid model.
 NL0937
 NL0937.GPS derived orthometric heights for airport stations designated as
 NL0937.PACS or SACS are published to 2 decimal places.  This maintains
 NL0937.centimeter relative accuracy between the PACS and SACS.  It does
 NL0937.not indicate centimeter accuracy relative to other marks which are
 NL0937.part of the published vertical control network.
 NL0937
 NL0937.Significant digits in the geoid height do not necessarily reflect accuracy.

 NJ0544'THE RAILROAD DISTANCE FROM V 80 INDICATES THE BLAIRS FERRY ROAD
 NJ0544'CROSSING. THE TRACKS WERE RECENTLY TORN OUT FROM THIS LOCALITY AND
 NJ0544'CONSIDERABLE RE-GRADING HAS BEEN DONE IN CONNECTION WITH WIDENING
 NJ0544'BLAIRS FERRY, EXPANDING BUSINESSES ALONG THE OLD RR RIGHT OF WAY, AND
 NJ0544'ADDING A SIDEWALK ALONG BLAIRS FERRY.
 NJ0544'
 NJ0544'ABOUT 70 YARDS FROM THE CROSSING ENE ALONG THE OLD RAILROAD ROUTE, AND
 NJ0544'DOWN THE RE-GRADED BANK ON THE NORTHERLY SIDE, IS THE END OF AN OLD 2
 NJ0544'FOOT CAST IRON CULVERT. THE SOUTHERLY END CAN BE SEEN THROUGH A
 NJ0544'MANHOLE ACCESS IN A NEW CONCRETE BOX ADJACENT TO BLAIRS FERRY ROAD
 NJ0544'WHICH CONNECTS TO A CULVERT UNDER THE ROAD. THE OLD CULVERT TERMINATES
 NJ0544'FLUSH WITH THE INSIDE OF THE BOX ABOUT 6 FEET BELOW THE SURFACE.
 NJ0544'
 NJ0544'THE OLD CONCRETE HEADWALL IS OR WAS JUST NORTH OF THE NEW BOX. THE
 NJ0544'DISK COULD BE BURIED THERE, BUT IS MOST LIKELY GONE GIVEN THE BROKEN
 NJ0544'CONDITION OR NEAR LACK OF CONCRETE ON OTHER CULVERTS ALONG THIS RAIL
 NJ0544'LINE.

 MG0914
 MG0914.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has 
 MG0914.been affixed to the stable North American tectonic plate. See 
 MG0914.www.ngs.noaa.gov/web/surveys/NA2011 for more information. 
 MG0914
 MG0914.The horizontal coordinates are valid at the epoch date displayed above
 MG0914.which is a decimal equivalence of Year/Month/Day.
 MG0914
 MG0914.The orthometric height was determined by GPS observations and a
 MG0914.high-resolution geoid model.
 MG0914
 MG0914.GPS derived orthometric heights for airport stations designated as
 MG0914.PACS or SACS are published to 2 decimal places.  This maintains
 MG0914.centimeter relative accuracy between the PACS and SACS.  It does
 MG0914.not indicate centimeter accuracy relative to other marks which are
 MG0914.part of the published vertical control network.
