After updating Google Earth, I decided to have a quick play with the new version to see if I could spot any new views. Elgin has a nice break in the cloud that still obscures most of the north east of Scotland, maybe one days the Americans will notice (I even emailed 'The Team' to complain').

Like an idiot, I thought I might try and identify the remains of an old flying school I found up there, near an ROC post, without checking out the lat/lon first. Pointless, but I did happen across some interesting ground formations, a little to the west of a disused airfield there that is now an antenna farm...

As I couldn't work out whether or not it was something interesting, I next fired up Multimap so I could shoot the same spot, but with OS mapping so that anything interesting would hopefully be identified....

I've set the zoom on the Multimap view to the max that you can hit the Map button for, and still select the OS view.

What's interesting about this is actually the vast difference between the Google aerial view and the Multimap aerial view. Doubtless both taken at different times, both show similar features, but in completely different locations.

Without having seen these two differing views together, I would have said that either might have been antenna masts, with their guy ropes radiating out to ground anchors, but that seem unlikely, unless they are part of some sort of temporary array, installed as required, and removed when not needed, possibly because they would not be robust enough to survive a decent wind.

Whatever the reason, it's still a handy reminder to give the other maps/aerial views a look since their imaging is always under review, and the current tiles may differ between each source at any given time.
