Just catching up on the week’s email that I had no time to answer, and noticed that the Earth Observatory‘s pictures of the week included one of London. If you know where to look, you can see Portman Square where the conference was held this week — a little square of greenery just to the northeast of Hyde Park.
You can subscribe to a weekly email that contains links to some very cool satellite images from the home page of the Earth Observatory site. I used to write software for analyzing satellite images so find this a particularly good distraction, but some of my non-remote-sensing friends also enjoy it.
