Herostratus, this is a valuable tool - thank you for giving this information including tutorial.
I used it for narrowing the dates for the Quarry Bay Gasholder. A feature of this size is easily recognisable even from higher flight altitudes. And you need a bit of luck to find the corresponding photos for desired dates and areas. So I was a bit disappointed in connection with houses on the peak after WWII. There are series from 1945, 1949, and 1956 from 20.000ft altitude - not many details to see.

Hi Klaus
Hi Klaus
There is an excellent series form May 1949 taken at 8600 feet which give a very clear view. Here is a sample:
Barker Road
Thank you, Herostratus. I didn't see this series. But again, photos taken from lower altitudes from 1945/46 would be desirable.
Nevertheless, this photo shows interesting details, e.g. that Victoria Hospital still stood in 1949 (althought not in use any more).
