30-cm Color WorldView-3/4 Image of the Month – Shanghai, China

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 January, we found ourselves in a coastal South African town, and for this WorldView-3/4 Image of the Month we travel to the Far East with a stop in the rapidly modernizing and expanding city of Shanghai, China.

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.

The downtown high-rise district of Shanghai is a site to see! So breaking with tradition this month, we feature a full resolution image of the entire (or nearly the entire) district with tall skyscrapers – enjoy! This 30-cm imagery was collected by WorldView-4 on November 1, 2017 and has been processed by Apollo Mapping for improved colors and clarity. (Images Courtesy: © 2018 DigitalGlobe)

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, WV3/4 will each be able to image every location daily with 1-meter or better resolution and then every 4.5 days at 34-cm resolution or better.
  • 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.
    • 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.

If you are interested in WorldView-3 and/or WorldView-4 imagery for your next project, please let us know by phone, 303-993-3863, or by email, sales@apollomapping.com.
