DF5873.The coordinates were established by GPS observations
DF5873.and adjusted by the National Geodetic Survey in June 2019.
DF5873
DF5873.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DF5873.been affixed to the stable North American Tectonic Plate.
DF5873
DF5873.The coordinates are valid at the epoch date displayed above
DF5873.which is a decimal equivalence of Year/Month/Day.
DF5873
DF5873.Due to the release of the International GNSS Service (IGS) 2014
DF5873.realization of the International Terrestrial Reference Frame of 2014
DF5873.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DF5873.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DF5873.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DF5873.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DF5873.currently published epoch of 2010.00.
DF5873
DF5873.Additional information on MYCS2 is available at
DF5873.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml

DF5873.** This station is in an area of suspected land subsidence, uplift, or
DF5873.** crustal motion. NGS recommends this and all published orthometric
DF5873.** heights in such areas be validated before use as vertical control.
DF5873.** Click here to see a list and map of nearby stations with valid
DF5873.** orthometric heights. Note: While datasheets are updated in real-time,
DF5873.** updates to archived datasheets and the SE TX Valid OH map occur
DF5873.** monthly. NGS discourages the use of scaled, VERTCON, or superseded
DF5873.** heights as vertical control as they are deemed unreliable.
DF5873.**
DF5873.** If an established orthometric height is unavailable in the survey control
DF5873.** section, it should be considered suspect. To view suspect heights,
DF5873.** (in the superseded section), select 'Include suspect heights in vertical
DF5873.** motion areas' box from the datasheet retrieval page.

DF5873.Significant digits in the geoid height do not necessarily reflect accuracy.

DF5873.The PID for the CORS L1 Phase Center is DH7237.

DF5873.The XYZ, and position/ellipsoidal ht. are equivalent.
DF5873
DF5873.The ellipsoidal height was determined by GPS observations
DF5873.and is referenced to NAD 83.
