 DH3618.The coordinates were established by GPS observations
 DH3618.and adjusted by the National Geodetic Survey in June 2019.
 DH3618
 DH3618.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has 
 DH3618.been affixed to the stable North American Tectonic Plate. 
 DH3618
 DH3618.The coordinates are valid at the epoch date displayed above
 DH3618.which is a decimal equivalence of Year/Month/Day.
 DH3618
 DH3618.Due to the release of the International GNSS Service (IGS) 2014
 DH3618.realization of the International Terrestrial Reference Frame of 2014
 DH3618.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
 DH3618.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
 DH3618.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
 DH3618.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
 DH3618.currently published epoch of 2010.00.
 DH3618
 DH3618.Additional information on MYCS2 is available at
 DH3618.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml

 DH3618.** This station is in an area of suspected land subsidence, uplift, or
 DH3618.** crustal motion. NGS recommends this and all published orthometric
 DH3618.** heights in such areas be validated before use as vertical control.
 DH3618.** Click here to see a list and map of nearby stations with valid
 DH3618.** orthometric heights.  Note: While datasheets are updated in real-time,
 DH3618.** updates to archived datasheets and the SE TX Valid OH map occur
 DH3618.** monthly. NGS discourages the use of scaled, VERTCON, or superseded
 DH3618.** heights as vertical control as they are deemed unreliable.
 DH3618.**
 DH3618.** If an established orthometric height is unavailable in the survey control
 DH3618.** section, it should be considered suspect. To view suspect heights,
 DH3618.** (in the superseded section), select 'Include suspect heights in vertical
 DH3618.** motion areas' box from the datasheet retrieval page.

 DH3618.Significant digits in the geoid height do not necessarily reflect accuracy.

 DH3618.The PID for the CORS L1 Phase Center is DK3565.

 DH3618.The XYZ, and position/ellipsoidal ht. are equivalent.
 DH3618
 DH3618.The ellipsoidal height was determined by GPS observations
 DH3618.and is referenced to NAD 83.
