30-cm Color WorldView-3/4 Image of the Month – Washington, D.C.

Every time we look at WorldView-3 and WorldView-4 (WV3/4) imagery, we are blown away. And we hope you are equally impressed with the data! In June, we stopped in one of world’s most colorful towns with one of its tallest buildings, and for this 30-cm Color WorldView-3/4 Image of the Month we keep our patriotic Fourth of July theme alive with a stop in our nation’s capital, the District of Columbia or Washington, D.C.



If you haven’t visited Washington, D.C. before, we suggest you make the voyage! The city is full of historic sites and peaceful walks along the Potomac River. In the three 30-cm WorldView-3 images that are featured here, the first is a gorgeous shot of the United States Capital with its iconic blue roof and white dome. We love the amazing globe courtyard in the second image and then how about that crazy geometrically-shaped building (by the way, it’s the National Museum of the American Indian) along the National Mall in the third? This amazing WorldView-3 image was collected on July 30, 2017 and has been processed by Apollo Mapping for improved colors and clarity. (Images Courtesy: DigitalGlobe)

PLEASE NOTE: Effective May 2016, WorldView-3/4 prices dropped again! Are you interested in finding out more about these price drops? If so, send us an email at sales@apollomapping.com.

WorldView-3 launched in late 2014 and WorldView-4 launched in late 2016; taken together they are the most advanced satellite constellation the commercial marketplace has ever had access to. Here are a few of the features that really set these satellites apart from the competition:

  • Improved Resolution
    • Higher resolution means you can see more detail in WV3/4 imagery.
    • Data collected at nadir will have 31-centimeter (cm) panchromatic, 1.24-meter (m) visible and near infrared, 3.7-m SWIR (WV3 only) and 30-m CAVIS (WV3 only) 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 WV3 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!), WV3/4 has no rivals for its enhanced positional accuracy.
  • Daily Revisits
    • At 40 degrees latitude, WV3 is able to image every location daily with 1-meter or better resolution and then every 4.5 days at 34-cm resolution or better.
    • WV4 is no longer collecting new imagery.
  • Increased Collection Capacity
    • WV3/4 feature 13.1-km swath widths (at nadir) with the ability to collect up to 680,000 square kilometer (sq km) of high-resolution data per day per satellite (though WV4 is dead now).
    • 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.
