Point of origin

From The Stargate Omnipedia


Term given to the final symbol on a Stargate address (the shape of which is often denoted by a characteristic of the planet in question). Without a point of origin, Stargate coordinates are incomplete and therefore useless. The symbol is often unique to the planet, and so may not appear on Stargates elsewhere in the galaxy.
