But in the last few days, Bing Maps - Microsoft's answer to Google Maps - seems to have plugged this gap with a lot of new high res coverage not available on Google. Select "Aerial" and zoom close in - you can't get an overview of where there is high res on Bing (because it's not universal) like you can on GE but there are areas where it seems like Bing takes over from where GE left off.
For example, GE does the south of Raasay well and Bing does the north and Rona. GE also does most of Coll but not Tiree whereas Bing does vice versa. Alas, neither does Oban yet (which is verging on criminal in my book). Anyway, here's Breacachadh Castle on Coll casting long shadows courtesy of Bing never before seen on GE as a taster:-
And here's a picture of the castle courtesy of my friend Doogie Greer:-
A minor niggle about Bing is you don't seem to be able to switch off the road map overlay over the aerial photos as you can in GE (which I found frustrating in Scarinish) but I'll let them off with that (for now).
