Google Map Escher Style

Look at the image I just copied from Google Map. We are in the very heart of Rome, where via Arenula crosses river Tiber.

Notice that on the left of the street you can see the northern façade of the buildings (shaded), while on the right you can see the southern (in full sunlight). This “Escher style” effect would be possible if buildings were bending in different directions due to a strong motion earthquake, or if the satellite were approaching the surface at almost the speed of light. Another explanation is that geeks at Google juxtapose images from different geostationary satellites (look at the tracks near the blue car turning on the bridge, they are slightly displaced). That’s real hard work guys, I appreciate it, but the result is a mess!
