30-cm Color WorldView-3/4 Image of the Month – LEGO House



Construction on the LEGO House started in 2014 and was completed in September 2017, which is about a year after this 30-cm WorldView-3 image was collected – but even at this stage it is a pretty amazing building. Built to resemble 21 giant LEGOs, the LEGO House is an experience for the whole family with its 25 million bricks! The other two images featured here are of the surrounding town of Billund which appears to be a quaint tourist destination as well. This 30-cm WorldView-3 was collected on September 26, 2016 and has been processed by Apollo Mapping for improved clarity and colors. (Satellite Imagery © 2021 Maxar Technologies)

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 March we checked out one of the tallest towers in the world located in China, and for the April edition of the 30-cm Color WorldView-3/4 Image of the Month we head to Billund, Denmark for some views of the LEGO House!

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.
  • 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.
