The Big Picture: Infrared satellite images reveal the true extent of a forest fire
DigitalGlobe's recently launched high-res imaging satellite isn't just in orbit for the sake of creating pretty pictures; it can also uncover things that you might never see at all. As proof, the company has posted before-and-after imagery of a California forest fire that shows off the advantages of WorldView-3's shortwave infrared sensor, which can easily see past clouds and smoke. Suffice it to say that the sensor's effect is dramatic -- areas that would have been completely obscured are suddenly in plain sight, revealing both the perimeter of the blaze and its intensity. The hope is that firefighters will use overhead shots like these to pinpoint areas where they're needed most, saving people and whole regions. It could be a while before emergency teams are pulling up satellite views at a moment's notice, but it won't be surprising if aircraft-based fire recon eventually becomes obsolete.
First satellite with high-resolution public imaging launches on August 13th
If you've been wondering just when a company would take advantage of the US' relaxed rules for accurate satellite imaging, you now have a date to mark on your calendar: Lockheed Martin has set the launch of DigitalGlobe's high-resolution WorldView-3 satellite for August 13th. You won't see results from it right away, but its creators can start selling extra-sharp pictures (with detail down to the 10-inch level) six months after the craft is up and running. The data should lead to much nicer imagery in online mapping services from companies like Google and Microsoft (both of which are DigitalGlobe customers), although it's not just cosmetic. Higher-res photos will help track large farms, spot mineral deposits and otherwise deliver a clearer view of our planet that has previously been limited to the government -- don't be surprised if it's easier to spot landmarks on a map without using markers.
