The cooperative network upgrading program began in tennessee in 1986.Understanding the difference between wgs84 and nad83 as a digital nomad, i often come across various geodetic datums and coordinate systems.
The national spatial reference system (nsrs), managed by the national geodetic survey (ngs), is a coordinate system that includes latitude, longitude, elevation, and other values.the nsrs consists of a national shoreline, the noaa cors network (a system of global positioning system continuously operating reference stations), a network of permanently marked points, and a set of models that.While they may seem similar, they serve slightly different purposes and have different applications …The north american datum of 1983 (nad 83) is the united states horizontal or geometric datum.

The primary distinction between these systems lies in the ellipsoid they use.Nad 83 and navd 88, although still the official horizontal and vertical datums of the national spatial reference system (nsrs), have been identified as having shortcomings that are best addressed through defining new horizontal and vertical datums.
This difference is known as a datum shift.Ngs coordinate conversion and transformation tool (ncat) (noaa.gov) autodesk have a labeled nad83 (2011) as nsrs11.The north american datum of 1983 corrected some of the.

Outside linebacker LaVar Arrington II, the son of former Penn State All-American and seven-year NFL veteran LaVar Arrington, announced his commitment to the Nittany Lions on Thursday.
Arrington II hails from Covina, California, and is a two-way standout at Charter Oak High School where he totaled 65 tackles and 12 sacks during his junior season last fall. The 6-foot-2, 210-pound defender held offers from the likes of Michigan, Washington and Colorado, and commits to his father's alma mater following spring visits to Penn State, Tennessee and UCLA.
The elder Arrington authored a career worthy of the College Football Hall of Fame with the Nittany Lions from 1997-99, where he emerged as one the nation's fiercest linebackers and became known for the "LaVar Leap." Arrington tallied 173 total tackles, 19 sacks and 3 interceptions on the way to back-to-back All-America selections, including unanimous honors in the 1999 season. That same year, Arrington took home the Butkus and Bednarik Awards, along with the Jack Lambert Trophy, while finishing ninth in Heisman Trophy voting.
Arrington was later selected by the Washington Redskins with the No. 2 pick in the 2000 NFL Draft and earned three Pro Bowl selections across seven seasons in the pros. In retirement, Arrington has launched a successful media career with footholds in television and radio.
With his pledge, Arrington II becomes the 21st member of James Franklin's 2025 class at Penn State, a group headlined by 10 ESPN prospects including Mater Dei cornerback Daryus Dixson, No. 90 in the 2025 ESPN 300. The Nittany Lions' incoming class ranks eighth in ESPN national team rankings for the 2025 class.
