DE5999.The coordinates were established by GPS observations
DE5999.and adjusted by the National Geodetic Survey in April 2022.
DE5999
DE5999.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DE5999.been affixed to the stable North American Tectonic Plate.
DE5999
DE5999.The coordinates are valid at the epoch date displayed above
DE5999.which is a decimal equivalence of Year/Month/Day.
DE5999
DE5999.Due to the release of the International GNSS Service (IGS) 2014
DE5999.realization of the International Terrestrial Reference Frame of 2014
DE5999.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DE5999.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DE5999.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DE5999.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DE5999.currently published epoch of 2010.00.
DE5999
DE5999.Additional information on MYCS2 is available at

DE5999.** This station is in an area of suspected land subsidence, uplift, or
DE5999.** crustal motion. NGS recommends this and all published orthometric
DE5999.** heights in such areas be validated before use as vertical control.
DE5999.** Click here to see a list and map of nearby stations with valid
DE5999.** orthometric heights. Note: While datasheets are updated in real-time,
DE5999.** updates to archived datasheets and the SE TX Valid OH map occur
DE5999.** monthly. NGS discourages the use of scaled, VERTCON, or superseded
DE5999.** heights as vertical control as they are deemed unreliable.
DE5999.**
DE5999.** If an established orthometric height is unavailable in the survey control
DE5999.** section, it should be considered suspect. To view suspect heights,
DE5999.** (in the superseded section), select 'Include suspect heights in vertical
DE5999.** motion areas' box from the datasheet retrieval page.
DE5999
DE5999.The orthometric height was determined by differential leveling and
DE5999.adjusted by the NATIONAL GEODETIC SURVEY
DE5999.in January 2021.
DE5999
DE5999.Significant digits in the geoid height do not necessarily reflect accuracy.

DE5999.The PID for the CORS L1 Phase Center is DO9489.

DE5999.The XYZ, and position/ellipsoidal ht. are equivalent.
DE5999
DE5999.The ellipsoidal height was determined by GPS observations
DE5999.and is referenced to NAD 83.
