Geoid 2009 Now Available

GEOID09: geoid height

GEOID03 - GEOID09: height
change

The National Geodetic Survey has released
two
new geoid models: gravimetric (USGG2009) and the more commonly used
hybrid (GEOID09). The hybrid model transforms from GPS height
measurements to NAVD88. The new models incorporate information from
satellite gravity and altimetry missions, and improved computation
methods. Kentucky contributed 126 data points which include GPS data on
benchmarks. The quality ellipsoid heights from the NSRS 2007 adjustment
and NAVD88 orthometric heights were used to model the geoid height
undulation for the GEOID09 hybrid geoid model.
