Oakland
From Memory Alpha, the free Star Trek reference
Oakland was a city on the planet Earth.
In 2151, an artist in Oakland was awaiting a decent photograph of Captain Jonathan Archer in order to paint Archer's portrait, which would in turn be hung on the wall in Starfleet Command in the captain's honor. (ENT: "Rogue Planet")
It was not established which Oakland the artist resided in. However, the writers most likely meant the city in California, as it is not only the largest city with that name, but is also the closest location to Starfleet Command in San Francisco.
