VERTCON for Google Earth (VERGE)
Requires Google Earth Version 5.0 or later.
VERGE is a graphical front end for the NGS online tool, VERTCON.
It eliminates the need to input geodetic coordinates and displays the converted
height and datum shift in a placemark balloon.
-
Position the point of interest (POI) in the center of the view. One way to
do this is to double-click an unmarked location. To precisely position the
POI in the center of the view, add a placemark at the desired location;
then edit the properties of that placemark and reset the view.
-
Check the box beside the Orthoheight Conversion network link.
A form will be presented with read-only coordinates corresponding to
the view center and input fields for height and datum. Converted height
and datum shift are displayed when the Convert button is pressed.
-
On subsequent uses, reposition the POI and ensure that the network link
is checked and selected. Then choose Refresh from the Edit menu, or right-click
and select Refresh in the context menu.
