Based on DGPS and CORS, America needs nationwide implementation of a standardized vertical reference datum as the legal basis for elevation data. 6-2 6.3 Finding #3. America needs high accuracy, high resolution Digital Elevation Models (DEMs) based on NAVD 88. 6-2 6.4 Finding #4. Based on NAVD 88, America needs a Nationwide Differential GPS (NDGPS) system for real-time accurate 3-D positioning; for navigation, tracking, public safety, precision farming, and construction 6-4 6.5 Finding #5.
