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! Last month we were down-under with a look at one of the greenest cities in the world, and for the April edition of the 30-cm Color WorldView-3/4 Image of the Month we head to one of the USA’s island territories with a look at Yauco, Puerto Rico.
When we picked out this location, we had hoped the selected 30-cm WorldView-3 image would show Yauco and all of its colorful houses. Unfortunately, as you can see in the first image, the colorful houses do not look so colorful when viewed from top-down, that’s too bad! But we still feature a few interesting WV3 images here, particularly the image of the (cell?) tower next to the remote storage building. This 30-cm WorldView-3 imagery was collected on May 15, 2019 and has been processed by Apollo Mapping for improved clarity and colors. (Satellite Imagery © 2022 Maxar Technologies)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.
- Improved Resolution
- 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.
