30-cm Color WorldView-3/4 Image of the Month – Lotte World Tower, Seoul, South Korea

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! From our May stop in an urban jungle in the Middle East, we head to Far East with a stop in one of the most vibrant and colorful cities in the world, Seoul, South Korea, focusing on the 5th tallest building in the world, the Lotte World Tower.




We think you will agree that Seoul is by far one of the coolest stops in this regular series both in terms of colors and architecture! The first image features the Lotte World Tower in all its 555-meter (1,821 feet) glory – we particularly love the golden buildings behind the tower, you rarely see that much gold in one location in imagery. The second photo which looks a bit like a collection of enchanted palaces is the amusement park, Lotte World Adventure, located at the foot of Lotte World Tower. The third features the geometric Olympic Gymnastics Arena; and the final image is a dizzying collection of equally-spaced and shaped roofs of all colors. These amazing 30-cm WorldView-3 images were collected on February 4, 2019 and have been processed by Apollo Mapping for improved clarity and colors. (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.

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.
