I don't know whether to be amazed or in fact even a little creeped out (not that you didn't know they could do this, but just to see yourself nonetheless)

Search on, say, your postal code. Click on satellite imagery and then zoom in all the way.
The Calgary map is a little old. Near as I can figure it's about 3, maybe 4 years old. It predates the Shawnessy Drive interchange anyhow. It shows my new house as being in a farmer's field. However I scrolled over to my old house, and there it was. I can see my house, my old birch tree, even my shed and my wife's car parked out in front.
I scrolled over to my work and one of those little cars parked in the lot must be my car...
A little surreal how detailed. Scroll over Fish Creek. Wow. Over to Glenmore Reservoir. You can see boats. You can see the SS. Moyie.
