30-cm Color WorldView-3 Image of the Month

Every time we look at WorldView-3 (WV3) imagery, we are blown away. And we hope you are equally impressed with the data! From the United States, we travel north to Norway with a 30-cm color look at Stavanger – a historic Nordic city located on the shores of the North Sea.

Stavanger_Norway_4_19_2015_WV3_30cmcolor_ENHANCE_IIIThree 30-cm natural color WorldView-3 images collected over Stavanger, Norway on April 19, 2015. In the first image, check out those small round picnic tables you can see by the football pitch. In the second, you can see purple detail on the circular roof by the Ferris wheel, purple is unusual in imagery. And in the final one, the pagoda in the park is quite cool! These images have been processed by Apollo Mapping to improve colors and clarity. (Images Courtesy: DigitalGlobe)

WorldView-3 was launched in late 2014 and is the most advanced satellite the commercial marketplace has ever had access to. Here are a few of the features that really set it apart from the competition:

  • Improved Resolution
    • Higher resolution means you can see more detail in WV3 imagery.
    • Data collected at nadir will have 31-centimeter (cm) panchromatic, 1.24-meter (m) visible and near infrared, 3.7-m shortwave infrared (SWIR) and 30-m CAVIS bands.
    • At 20 degrees off-nadir, the resolution is 34-cm panchromatic, 1.38-m visible and near infrared and 4.1-m shortwave infrared.
    • Per US government regulation, all SWIR orders are produced at a maximum resolution of 7.5-m. CAVIS bands are not available for purchase at this time.
  • Additional Spectral Bands
    • If spectral analysis is part of your project, then no other satellite can match WV3 with its: 8 bands of visible and near-infrared data; and 8 shortwave infrared bands which are crucial for geological studies.
  • Better Positional Accuracy
    • With accuracies of 3.5-m CE90% or better (without ground control even!), WV3 has no rivals for its enhanced positional accuracy.
  • Daily Revisits
    • At 40 degrees latitude, WV3 will be able to image each location daily with 1-meter or better resolution and then every 4.5 days at 34-cm resolution or better.
  • Increased Collection Capacity
    • WV3 features a 13.1-km swath width (at nadir) with the ability to collect up to 680,000 square kilometer (sq km) of high-resolution data per day.
    • Improved control movement gyros translate into larger maximum contiguous collection areas per pass, with up to ~7,500 sq km of mono imagery and ~3,000 sq km of stereo possible.
