Signing In

Sign into the GeoCalc Geodetic Registry using your Blue Marble Website account information. If you have not registered for a Blue Marble Website account you may do so here:

Signing in will allow you access to Actions associated with search results (such as viewing the WKT or GML). Signing in while associated with a Geographic Calculator order will also allow you access to the Point to Point Calculator.
If you have a current Calculator license the registry should recognize that by your log in information. If the registry cannot find your order, or if you need assistance linking your registered account to your current Geographic Calculator order, please contact .
