DP2490.The coordinates were established by GPS observations
DP2490.and adjusted by the National Geodetic Survey in March 2022.
DP2490
DP2490.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DP2490.been affixed to the stable North American Tectonic Plate.
DP2490
DP2490.The coordinates are valid at the epoch date displayed above
DP2490.which is a decimal equivalence of Year/Month/Day.
DP2490
DP2490.Due to the release of the International GNSS Service (IGS) 2014
DP2490.realization of the International Terrestrial Reference Frame of 2014
DP2490.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DP2490.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DP2490.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DP2490.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DP2490.currently published epoch of 2010.00.
DP2490
DP2490.Additional information on MYCS2 is available at

DP2490.** This station is in an area of suspected land subsidence, uplift, or
DP2490.** crustal motion. NGS recommends this and all published orthometric
DP2490.** heights in such areas be validated before use as vertical control.
DP2490.** Click here to see a list and map of nearby stations with valid
DP2490.** orthometric heights. Note: While datasheets are updated in real-time,
DP2490.** updates to archived datasheets and the SE TX Valid OH map occur
DP2490.** monthly. NGS discourages the use of scaled, VERTCON, or superseded
DP2490.** heights as vertical control as they are deemed unreliable.
DP2490.**
DP2490.** If an established orthometric height is unavailable in the survey control
DP2490.** section, it should be considered suspect. To view suspect heights,
DP2490.** (in the superseded section), select 'Include suspect heights in vertical
DP2490.** motion areas' box from the datasheet retrieval page.

DP2490.Significant digits in the geoid height do not necessarily reflect accuracy.

DP2490.The XYZ, and position/ellipsoidal ht. are equivalent.
DP2490
DP2490.The ellipsoidal height was determined by GPS observations
DP2490.and is referenced to NAD 83.
