DH3602.The coordinates were established by GPS observations
DH3602.and adjusted by the National Geodetic Survey in June 2020.
DH3602
DH3602.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DH3602.been affixed to the stable North American Tectonic Plate.
DH3602
DH3602.The coordinates are valid at the epoch date displayed above
DH3602.which is a decimal equivalence of Year/Month/Day.
DH3602
DH3602.Due to the release of the International GNSS Service (IGS) 2014
DH3602.realization of the International Terrestrial Reference Frame of 2014
DH3602.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DH3602.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DH3602.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DH3602.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DH3602.currently published epoch of 2010.00.
DH3602
DH3602.Additional information on MYCS2 is available at

DH3602.** This station is in an area of suspected land subsidence, uplift, or
DH3602.** crustal motion. NGS recommends this and all published orthometric
DH3602.** heights in such areas be validated before use as vertical control.
DH3602.** Click here to see a list and map of nearby stations with valid
DH3602.** orthometric heights. Note: While datasheets are updated in real-time,
DH3602.** updates to archived datasheets and the SE TX Valid OH map occur
DH3602.** monthly. NGS discourages the use of scaled, VERTCON, or superseded
DH3602.** heights as vertical control as they are deemed unreliable.
DH3602.**
DH3602.** If an established orthometric height is unavailable in the survey control
DH3602.** section, it should be considered suspect. To view suspect heights,
DH3602.** (in the superseded section), select 'Include suspect heights in vertical
DH3602.** motion areas' box from the datasheet retrieval page.

DH3602.Significant digits in the geoid height do not necessarily reflect accuracy.

DH3602.The PID for the CORS L1 Phase Center is DQ7753.

DH3602.The XYZ, and position/ellipsoidal ht. are equivalent.
DH3602
DH3602.The ellipsoidal height was determined by GPS observations
DH3602.and is referenced to NAD 83.
