DN4506.The coordinates were established by GPS observations
DN4506.and adjusted by the National Geodetic Survey in April 2022.
DN4506
DN4506.NAD 83(2011) refers to NAD 83 coordinates where the reference frame has
DN4506.been affixed to the stable North American Tectonic Plate.
DN4506
DN4506.The coordinates are valid at the epoch date displayed above
DN4506.which is a decimal equivalence of Year/Month/Day.
DN4506
DN4506.Due to the release of the International GNSS Service (IGS) 2014
DN4506.realization of the International Terrestrial Reference Frame of 2014
DN4506.(ITRF2014), NGS reprocessed all NOAA CORS Network and some IGS stations
DN4506.using data collected between 1/1/1996 and 1/30/2017. The resulting ITRF2014
DN4506.epoch 2010.00 coordinates, referred to as Multi-Year CORS Solution 2
DN4506.(MYCS2), were transformed to NAD 83 (2011/PA11/MA11) maintaining the
DN4506.currently published epoch of 2010.00.
DN4506
DN4506.Additional information on MYCS2 is available at
DN4506.https://geodesy.noaa.gov/CORS/news/mycs2/mycs2.shtml

DN4506.** This station is in an area of suspected land subsidence, uplift, or
DN4506.** crustal motion. NGS recommends this and all published orthometric
DN4506.** heights in such areas be validated before use as vertical control.
DN4506.** Click here to see a list and map of nearby stations with valid
DN4506.** orthometric heights. Note: While datasheets are updated in real-time,
DN4506.** updates to archived datasheets and the SE TX Valid OH map occur
DN4506.** monthly. NGS discourages the use of scaled, VERTCON, or superseded
DN4506.** heights as vertical control as they are deemed unreliable.
DN4506.**
DN4506.** If an established orthometric height is unavailable in the survey control
DN4506.** section, it should be considered suspect. To view suspect heights,
DN4506.** (in the superseded section), select 'Include suspect heights in vertical
DN4506.** motion areas' box from the datasheet retrieval page.
DN4506
DN4506.The orthometric height was determined by GPS observations and a
DN4506.high-resolution geoid model using precise GPS observation and
DN4506.processing techniques.
DN4506
DN4506.Significant digits in the geoid height do not necessarily reflect accuracy.
DN4506.GEOID18 height accuracy estimate available here.

DN4506.The PID for the CORS L1 Phase Center is DR7785.

DN4506.The XYZ, and position/ellipsoidal ht. are equivalent.
DN4506
DN4506.The ellipsoidal height was determined by GPS observations
DN4506.and is referenced to NAD 83.
