Ballmer and Co. have loaded up Bing Maps with yet another batch of images, and though they're staying quiet about the update's file size this time, they say it includes 13,799,276 square kilometers of fresh high-res satellite shots and a better view of the ocean floor. Brand-new "straight down" photos give the base map a resolution of 15 meters per pixel, and the introduction of bathymetric imagery changes the ocean's hue depending on its depth. The refresh even contains fewer clouds, giving users a less obstructed view of Earth. Thanks to additional aerial photos covering 203,271 square kilometers, Microsoft's map service now covers the entirety of the US and 90 percent of Western Europe with pictures taken from aircraft. Armchair cartographers ready to explore the world remotely can find the revamped visuals already baked into Bing Maps online and within the service's Windows 8 app.
