30-cm Color WorldView-3/4 Image of the Month – Lake Pehoé, Chile



Bienvenido to the stunning Lake Pehoé in Chile. Pehoe (Pronounced “pay-oh-way”) is a Tehuelche word meaning ‘hidden’.  This turquoise, glacial lake is set against the grandeur of the Andes Mountains. It is located in Torres del Paine National Park, in the Magallanes Region of southern Chile. This park is one of the most popular tourist destinations in the region, known for its hiking, backpacking and peaceful campsites. In 2013, the area was elected the fifth most beautiful place in the world by National Geographic Magazine. These WorldView-3 images of Lake Pehoé were collected on January 18, 2016, and truly showcase the stunning, ethereal blue shade of the water. This 30-cm WorldView-3 imagery has been processed by Apollo Mapping for improved perspective, clarity and colors. (Satellite Imagery © 2022 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 October we took a look at Lake Como in Italy, and for this edition of the 30-cm Color WorldView-3/4 Image of the Month we’re heading to nearly the other side of the world with a look at the lovely Lake Pehoé in Chile.

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
