The National Geodetic Survey has released updated models for transforming heights between ellipsoidal coordinates and physical height systems that relate to water flow. These models cover regions including the conterminous United States (CONUS), Alaska, Hawaii, Guam and the Commonwealth of the Northern Mariana Islands, and American Samoa. Models for Puerto Rico and the U.S. Virgin Islands are being held back pending release of final control data for the USVI but will likely be released later this Fall. GEOID09 transforms to NAVD 88 in CONUS and Alaska and to the respective datums for all the other regions (each having its own datum point). Models for the Deflection of the Vertical have also been released for these same regions mainly for aid in navigation systems.
