The higher resolution looks nice. One of the problems with using modern aerial pics is you want to locate regions where only 65+ year old buildings are visible, which can be a problem, unless you are a local and know what you're looking at; and then you want to go through the pics and remove modern items like brightly coloured cars - in 1940, there were almost entirely only dark colours and blacks, except for the rare roadster. Also, I wonder about the paving - I suspect there weren't a lot of curbs and sidewalks in the suburbs, similar to how it was in north america, where most of that stuff was put in during the 50s and 60s.
To get an idea what things should look like, you can access The RAF WWII Aerial Reconaissance photo Archive, TARA, which is now handled by "Cities Revealed". It has many views of southern England in 1941-3 (in B&W, of course), if you can cope with their bizarre user interface. The site is here:
Click on the "Find Image", then flail helplessly in the face of their boneheaded shockwave-flash map navigation scheme. In my tutorial, I talk very briefly about how to navigate their system. It uses "National Grid Reference" points, but I haven't found a convenient map yet to look up the numbers easily. If you are fortunate enough to stumble on a suburb image, you can get more magnification by using your mouse wheel (if you have one) than they allow with their little + button.
