The document summarizes plans by Hawaii state agencies and the National Geodetic Survey to modernize Hawaii's spatial reference systems. Hawaii DOT is funding a 5-phase plan to establish a new digital leveling network, continuous GPS reference station network, and LIDAR data. The NGS has established a new national spatial reference system called NAD 83(2011) based on reprocessing data from over 2000 GPS reference stations from 1994-2011. By 2022, the NGS aims to establish new geometric and vertical datums to further improve positioning accuracy across the United States.
