DF5352.The coordinates were established by GPS observations
DF5352.and adjusted by the National Geodetic Survey in June 2019.
DF5352
DF5352.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DF5352.been affixed to the stable North American Tectonic Plate.
DF5352
DF5352.The coordinates are valid at the epoch date displayed above
DF5352.which is a decimal equivalence of Year/Month/Day.
DF5352
DF5352.Due to the release of the International GNSS Service (IGS) 2014
DF5352.realization of the International Terrestrial Reference Frame of 2014
DF5352.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DF5352.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DF5352.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DF5352.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DF5352.currently published epoch of 2010.00.
DF5352
DF5352.Additional information on MYCS2 is available at

DF5352.** This station is in an area of suspected land subsidence, uplift, or
DF5352.** crustal motion. NGS recommends this and all published orthometric
DF5352.** heights in such areas be validated before use as vertical control.
DF5352.** Click here to see a list and map of nearby stations with valid
DF5352.** orthometric heights. Note: While datasheets are updated in real-time,
DF5352.** updates to archived datasheets and the SE TX Valid OH map occur
DF5352.** monthly. NGS discourages the use of scaled, VERTCON, or superseded
DF5352.** heights as vertical control as they are deemed unreliable.
DF5352.**
DF5352.** If an established orthometric height is unavailable in the survey control
DF5352.** section, it should be considered suspect. To view suspect heights,
DF5352.** (in the superseded section), select 'Include suspect heights in vertical
DF5352.** motion areas' box from the datasheet retrieval page.

DF5352.Significant digits in the geoid height do not necessarily reflect accuracy.

DF5352.The XYZ, and position/ellipsoidal ht. are equivalent.
DF5352
DF5352.The ellipsoidal height was determined by GPS observations
DF5352.and is referenced to NAD 83.
