My Googling skills may be bad, but I have found no map or reference for the Spacex landing pad location. Probably somewhere near Cape Canaveral, but where?
The new Landing Zone 1, is the old LC-13, at the south end of Missile Row. Interestingly the initial SpaceX name was Landing Complex 1 (LC-1) which was confusing and just before this landing the sign was renamed to Landing Zone 1, LZ-1, less confusing.
Wikipedia has been updated, so that Launch Complex 13 now redirects to Landing Zone 1, which is kind of fun!
Here is a link on Google Maps, which is not yet updated with imagery showing the LZ-1 configuration.
Here is an image of the various launch complexes at Cape Canaveral. You can see down at the bottom end that LC-13 is shown as Inactive in 2003, which is true.
The launch was from LC-40, further north, and SpaceX has a lease on LC-39A, for manned launches and Falcon Heavy launches.
