Google Maps Readabilty
I'm a big fan of Justin O'Beirne's 41Latitude blog about maps, technology and usability. Justin's two posts on the Google Maps Styled Maps feature, Styled Maps Using Google Maps API Version 3 and Additional Examples of Styled Maps Using Google Maps API V3 are essential reading for anyone who wants to add a little style to their Google Maps creations.
Justin has posted a new article today on the readability of the major online map providers. The article provides some excellent analysis of the variety of techniques and visual tricks used by Google Maps to make its city labels much more readable than those of its competitors. The article is illustrated throughout with some excellent comparisons between Google Maps and its competitors, such as Bing Maps and Yahoo Maps.
Friday Fun with Google Maps
The problem with living in a major city is that light pollution ruins your appreciation of the stars. That's why urban stag-gazing has been invented.
Mapping a Day in Twitter
Chris McDowall has used Matplotlib with the Basemap extension to animate 25 hours of Tweets on a world map.
Streeview Names
Now that Street View blurs faces Google has decided to start adding name tags to people so that you can know who they are. Unfortunately, for those who want to be named, you have to have the name of a nearby store.

Google Earth continues to reveal strange sights from above
Over the years, we've seen a variety of interesting items revealed as result of Google Earth.
One of the most popular was the Swastika-shaped Navy Barracks that Frank first told you about in 2007. For years it was a simple building, but it gained fame once viewed from above, as it was clearly (though certainly unintentionally) shaped like a Nazi swastika.
Another great example was the huge scale model of China that was discovered. It represented an area that was occupied by China but claimed by India and was in dispute, and the model itself was nearly a square kilometer in size.
The latest example is the Star of David being discovered on the roof of the Iran Air headquarters. The building was constructed in 1979, and it seems that no one noticed the symbol until now. Unlike the Navy swastika building, this symbol was clearly intentional, though it's unclear who placed it there.
Iranian government officials are quite upset by this, and plan to have it removed quickly. However, it may stay in Google Earth for a few years, or at least until the imagery in that area is updated again. If you'd like to see it for yourself, you can fly there using this KML file.
If you enjoy seeing strange items like this, there are a few categories full of fun items like this over at Google Earth Hacks: Crop Circles, Huge Man-Made Structures and Huge Symbols. You can also check out the great "20 Awesome Images Found in Google Maps" post by Search Engine Land,

Google Earth Engine, an amazing tool for scientists and researchers, released at COP 16
Yesterday at the International Climate Change Conference, Google released a mountain of data for scientists around the world to analyze and use. Known as "Google Earth Engine", it gives researchers access to this huge pile of data, along with computing power to deal with all of it.
The data includes Landsat satellite data and "trillions of scientific measurements" covering the past 25 years.
So what can be done with all of this data? Thanks to some launch partners, there are already a handful of projects underway. For example, below is a map showing the loss of forest cover in the Congo for the past 10 years, taken from the Earth Engine Map Gallery.
To go along with this, Google is also donating 10 million CPU-hours for each of the next two years, to help developing nations track the state of their forests. This is in anticipation forREDD (Reducing Emissions from Deforestation and Forest Degradation in Developing Countries), which offers financial incentives for tropical nations that protect their forests.
Do you plan to use Google Earth Engine? If not, what would you use it for if you had the chance?
