GOM - the Global Overlay Mapping System

The About Button & Popup Window

To view the popup 'About' window, click on the 'About' button located to the right of the upper toolbar. The 'About' window contains information about the Global Overlay Mapping System, including Software Version, Overlay Version, Licensee Callsign, Registered Position of your station, and Licensee Serial Number.

Your Callsign and Registered Position are encoded into the software when you purchased it. If you wish to change your Registered Position, send an email to the address on the Contact Page containing the new position, your Callsign, and the Licensee Serial Number. Position changes are limited to 1 per year, unless other terms are agreed on with the author. Callsign changes are not possible.
