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 checked out one of the world’s tallest buildings located in Southeast Asia, and for this 30-cm Color WorldView-3/4 Image of the Month we travel to the Saharan Desert with a look at one of the best named cities in the world, Timbuktu, Mali.
While Timbuktu has the most iconic name of any city we could think of, admittedly the scenery in the town is, well, not as iconic. Set against a backdrop of reds, beiges and browns that dominate the Saharan landscape, we struggled to find any color in the city as these three images attest too – keep in mind, these are literally the most colorful structures we could find! Either way, these 30-cm WorldView-3 images were collected on August 21, 2015 when it was exceptionally green (at least for the desert) and have been processed by Apollo Mapping for improved clarity and colors.

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.
