AJ8805.The coordinates were established by GPS observations
AJ8805.and adjusted by the National Geodetic Survey in June 2019.
AJ8805
AJ8805.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
AJ8805.been affixed to the stable North American Tectonic Plate.
AJ8805
AJ8805.The coordinates are valid at the epoch date displayed above
AJ8805.which is a decimal equivalence of Year/Month/Day.
AJ8805
AJ8805.Due to the release of the International GNSS Service (IGS) 2014
AJ8805.realization of the International Terrestrial Reference Frame of 2014
AJ8805.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
AJ8805.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
AJ8805.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
AJ8805.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
AJ8805.currently published epoch of 2010.00.
AJ8805
AJ8805.Additional information on MYCS2 is available at
AJ8805.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml

AJ8805.** This station is in an area of suspected land subsidence, uplift, or
AJ8805.** crustal motion. NGS recommends this and all published orthometric
AJ8805.** heights in such areas be validated before use as vertical control.
AJ8805.** Click here to see a list and map of nearby stations with valid
AJ8805.** orthometric heights. Note: While datasheets are updated in real-time,
AJ8805.** updates to archived datasheets and the SE TX Valid OH map occur
AJ8805.** monthly. NGS discourages the use of scaled, VERTCON, or superseded
AJ8805.** heights as vertical control as they are deemed unreliable.
AJ8805.**
AJ8805.** If an established orthometric height is unavailable in the survey control
AJ8805.** section, it should be considered suspect. To view suspect heights,
AJ8805.** (in the superseded section), select 'Include suspect heights in vertical
AJ8805.** motion areas' box from the datasheet retrieval page.
AJ8805
AJ8805.The orthometric height was determined by GPS observations and a
AJ8805.high-resolution geoid model using precise GPS observation and
AJ8805.processing techniques.
AJ8805
AJ8805.Significant digits in the geoid height do not necessarily reflect accuracy.
AJ8805.GEOID18 height accuracy estimate available here.

AJ8805.The PID for the CORS L1 Phase Center is DQ9066.

AJ8805.The XYZ, and position/ellipsoidal ht. are equivalent.
AJ8805
AJ8805.The ellipsoidal height was determined by GPS observations
AJ8805.and is referenced to NAD 83.
