View NGS VERTCON for Google Earth

National Geodetic Survey (NGS) calculates the datum shift between NGVD 1929 and NAVD 1988 at http://www.ngs.noaa.gov/cgi-bin/VERTCON/vert_con.prl.  NGS calculates this datum shift using Latitude and Longitude.  This web application simply reports the datum shift as a placemark within Google Earth.  Google Earth needs be be installed (http://earth.google.com) before successfully using the link below.

Open the NGS_Vertcon.kml file in Google Earth.  It will dynamically query NGS's database based on the center coordinates of Google Earth.  It will display a placemark with the datum shift.
