There&#x27;s a site where you can see this really clearly, <a href="http:&#x2F;&#x2F;www.historicaerials.com&#x2F;" rel="nofollow">http:&#x2F;&#x2F;www.historicaerials.com&#x2F;</a> ... it&#x27;s a pretty bad site but the only one I know that actually presents the data in this way.<p>The first image:  <a href="http:&#x2F;&#x2F;historicaerials.com:?layer=T1963&amp;zoom=16&amp;lat=34.09750190321817&amp;lon=-118.35163593292235" rel="nofollow">http:&#x2F;&#x2F;historicaerials.com:?layer=T1963&amp;zoom=16&amp;lat=34.09750...</a> ... if you go to the compare drop-down, select slide, then do 2012, you can clearly see this.
