How did you all do in the quiz? As you were browsing around the globe trying to find the answers, did you happen to notice that the coastlines look a lot prettier than before? If so, you've earned some extra credit. One of the features of this update was a 'Global Coastline Mask' for the coastlines. Before this, you would see jagged edges from multiple images at the coastlines. With this update, we have made the coastlines more realistic and cleaner. Here is a before and after shot of some islands and coastlines showing you the effect of this change.

We have tried to ensure that we retain all the significant ocean features and structures, but if you think you've spotted any area where we have accidentally masked out an important feature, please report it to us via this form. (select 'blacked out' category).

New 2.5m base imagery for: The Galapagos, The Falkland Islands, Yemen, Oman, Bulgaria, and Albania

Sometimes our imagery updates are much broader than this brief list indicates. Our satellite partners give us tons of fantastic data, often spread out over a very diverse set of locales, so it can be hard to translate that into a condensed list of city names. To highlight some of these areas, we decided to have some fun putting together a KML this month that details some of the updates. We hope that this encourages everyone to explore the new imagery and find interesting and exciting discoveries. You can download the KML here.
