Dubai is undergoing what could be called some 'serious' development work in the last few years. They are building entire new islands in a variety of funky shapes for the mega rich to buy holiday homes on. A downside of this is that the geographical layout changes very quickly, too quickly is seems for any of the internet mapping tools to keep up.
I was disappointed when looking at Dubai for some client Google Earth work to see how out of date all the maps are. I expected them to be updated regularly just because of how amazing the Dubai developments are, but alas this is not the case. For example take a look at the Google Earth current coverage.
You can see the 2 new 'palm island' developments on the map, however since then they have built the 'World' and another palm. I've found a Google Earth overlay that shows the updated development, but the overlay is a bit rough. Here is a screenshot.
