DF4375.The coordinates were established by GPS observations
DF4375.and adjusted by the National Geodetic Survey in June 2019.
DF4375
DF4375.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DF4375.been affixed to the stable North American Tectonic Plate.
DF4375
DF4375.The coordinates are valid at the epoch date displayed above
DF4375.which is a decimal equivalence of Year/Month/Day.
DF4375
DF4375.Due to the release of the International GNSS Service (IGS) 2014
DF4375.realization of the International Terrestrial Reference Frame of 2014
DF4375.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DF4375.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DF4375.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DF4375.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DF4375.currently published epoch of 2010.00.
DF4375
DF4375.Additional information on MYCS2 is available at
DF4375.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml

DF4375.** This station is in an area of suspected land subsidence, uplift, or
DF4375.** crustal motion. NGS recommends this and all published orthometric
DF4375.** heights in such areas be validated before use as vertical control.
DF4375.** Click here to see a list and map of nearby stations with valid
DF4375.** orthometric heights. Note: While datasheets are updated in real-time,
DF4375.** updates to archived datasheets and the SE TX Valid OH map occur
DF4375.** monthly. NGS discourages the use of scaled, VERTCON, or superseded
DF4375.** heights as vertical control as they are deemed unreliable.
DF4375.**
DF4375.** If an established orthometric height is unavailable in the survey control
DF4375.** section, it should be considered suspect. To view suspect heights,
DF4375.** (in the superseded section), select 'Include suspect heights in vertical
DF4375.** motion areas' box from the datasheet retrieval page.

DF4375.Significant digits in the geoid height do not necessarily reflect accuracy.

DF4375.The PID for the CORS L1 Phase Center is DF4376.

DF4375.The XYZ, and position/ellipsoidal ht. are equivalent.
DF4375
DF4375.The ellipsoidal height was determined by GPS observations
DF4375.and is referenced to NAD 83.
