NOAA's modernised positioning system key to improved mapping, emergency and land planning

NOAA's National Geodetic Survey - the official U.S. government source for determining precise latitude, longitude and elevation - is undergoing a modernisation effort that takes into account advances in GPS and other technologies. The effort is important to all activities requiring accurate positioning information including levee construction projects, the design of evacuation routes in hurricane-prone areas and the forecast of sea-level rise in coastal communities. The modernised National Spatial Reference System will take even greater advantage of newer technologies and better track changes in position and elevation over time to improve and update digital maps...
