NASA Releases New High-Definition Image of Earth

Posted by timothy on from the texas-centric-view dept.

New submitter klchoward writes "Working for NOAA, I have been really pleased to see the weather data from the new Suomi NPP satellite coming into our computer models already but have been blown away by its capability to take stunning high-definition images of our planet. See the article at Huffington Post or go straight to the image at NASA's website." Reader derekmead has some images from further afield, too: these beautiful images of Mars come from NASA's High Resolution Imaging Science Experiment camera, mounted on the Mars Reconnaissance Orbiter.

      The overall(presumably composite) pic is pretty cool looking; but does anybody know if they have the data available in the less-immediately-elegant-but-rather-more-useful georectified form?

      As wallpaper, the press shot can hardly be beat. If they have the GeoTIFFs somewhere, though, that would have much broader application...

      I'm not sure I'm following where you're leading. This is a composite; it's a composite of Earth-view swaths of a sun-synchronous polar orbiting earth observation satellite. The "native geolocation space" of the images is a swath approximately 3000 km wide and tracking under the orbital path of the spacecraft (i.e., ground-track Mercator). This image is based on reprojecting those swaths to the geoid, so it looks like you're floating above the Equator and looking down at Earth.

      As to anti-aliasing, I dunno. This isn't a standard product of Suomi's ground system, so whatever aesthetic and technical decisions are reflected in this image are entirely on the NASA folks who did this.

  7. Looks like it is photoshopped. by 140Mandak262Jamuna · · Score: 5, Funny

    Looks like they have done some serious photoshopping. I could not see any of the lines showing the state borders. May be they erased it for security reasons. Also I did not see the pink tear drop like thingie with A, B etc written on it. Simply put, it does not look anything like the satellite images I have seen in maps.google.com.

  11. Re:Too Large by Sockatume · · Score: 3, Informative

    Actually on further inspection it seems that this was electronically generated from sweeps of the Earth, and therefore they could've chosen any perspective they wanted, but the horizon distance in the image is correct for someone looking from 500 miles above that spot.

  12. It's not a photograph by Guspaz · · Score: 4, Informative

    It's pretty, but it's not a photograph of the earth. It's CG; a rendering of a sphere texturemapped with images of the surface of the planet that they captured. Neither NASA nor huffpost are misrepresenting what it is, but there's something special about the original blue marble, which is an actual *photograph* of the entire planet, not something thrown together in 3ds max.

      It's a little sad that the last time any human was able to see the entire earth at once was December 1972. That's like traveling across the ocean and then coming home and sitting on your front porch for the next 30 years.

      Apparently, it was named after Verner Suomi, so it's not a direct reference to our country, but there is a Finnish ancestry nevertheless.
