DEFLEC12A and USDOV2012 Models Released
The National Geodetic Survey has released both the DEFLEC12A and USDOV2012 models. These models are companion products to the GEOID12A and USGG2012 models, respectively. They are intended for use in determining the angular difference of the plumbline relative to a specific reference frame (NAD 83 and IGS08/GRS-80, respectively).

NGS requests your patience while we update the "bluebooking" process for GPS projects.
While we update the adjust guidelines, submissions for all GPS projects are being postponed until the new "bluebooking" processes are posted. A notice will be posted here when this is accomplished. Thank you for your cooperation.
NOTICE: NGS Update, September 11, 2012
GEOID12A Model Released
The National Geodetic Survey has released the GEOID12A model. Analysis of the underlying control data has been completed and a number of corrections were made to the original data used in making GEOID12. Changes impacted regions in the states of Alabama, Mississippi, Louisiana, Texas, Oklahoma, and Wisconsin. GEOID12A is now available for production and use.The National Geodetic Survey Improves the National Spatial Reference System with Simultaneous Major Product Releases
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

NGS Releases Final Report for Floodplain Mapping Pilot Project
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
A 2009 independent study shows the benefits to the U.S. economy from NOAA's positioning products and services are in the billions of dollars.

10/18/2012 - Enabling Historical "T-Sheets" to be Accurately and Efficiently Geo-referenced
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
