In the first week of July, NOAA’s National Geodetic Survey (NGS) released the results of three major improvements to the National Spatial Reference System (NSRS). The NSRS is the consistent coordinate system that defines latitude, longitude, height, scale, gravity, and orientation throughout the United States and its territories...more
This week, NOAA released a new web application to allow users to view National Geodetic Survey (NGS) geodetic control across the United States and its territories using Google Maps...more

As NGS moves closer to 2022 and replacing the North American Datum of 1983 (NAD 83) and the North American Vertical Datum of 1988 (NAVD 88), NGS is interacting closely with agencies that use the datums to assist in the transition...more

The week of October 22, the National Geodetic Survey (NGS) played a lead role in GeoTech 2012, the annual conference of the American Society for Photogrammetry and Remote Sensing Potomac Region.....more
Historical Topographic Sheets ("T-Sheets") produced by the U.S. Coast and Geodetic Survey are referenced to various horizontal datums in use over the two hundred years since the first Survey of the Coast in 1816. To use these maps to document coastal change, a conversion has to be made from the horizontal datum used at the time the map was published to the datum in which modern data are expressed. Upon successful completion of rigorous testing now underway, the National Geodetic Survey (NGS) will soon provide a free...more
This week, NOAA's National Geodetic Survey (NGS) and Office of Coast Survey (OCS) participated in Know the Coast Day, an educational open house for K-12 students and the general public at the University of New Hampshire (UNH) Joint Hydrographic Center Center for Coastal and Ocean Mapping...more
NGS is representing the United States at the International Symposium on Gravity, Geoid, and Height Systems in Venice, Italy on Oct. 9–12. The symposium will address the creation and maintenance of global vertical height systems, which are critical for many surveying, engineering, and scientific activities...more
