Every time we look at WorldView-3 (WV3) imagery, we are blown away. So we have decided to make this article a monthly feature for the viewing joy of our valued readers. This month, we feature four color 40-cm WV3 images collected over Santiago, Chile.
If you have not heard of the recently-launched satellite, WorldView-3, here are the features that really set it apart from the competition:
- Improved Resolution
- Higher resolution means you can see more detail in WV3 imagery.
- Data collected at nadir will have 31-centimeter (cm) panchromatic, 1.24-meter (m) visible and near infrared, 3.7-m short-wave infrared and 30-m CAVIS bands.
- At 20 degrees off-nadir, the resolution is 34-cm panchromatic, 1.38-m visible and near infrared and 4.1-m short-wave infrared.
- With the easing of US government regulations, we will be able to provide WV3 imagery at a maximum of 30-cm resolution during Q1 2015.
- 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; 8 shortwave infrared bands which are crucial for geological studies; and 12 CAVIS bands to detect water vapor, dissolved aerosols, snow, clouds and more.
- Better Positional Accuracy
- With accuracies of 3.5-m CE90% or better (without ground control even!), WV3 has no rivals for its enhanced positional accuracy.
- Daily Revisits
- At 40 degrees latitude, WV3 will be able to image each location daily with 1-meter or better resolution and then every 4.5 days at 34-cm resolution or better.
- Increased Collection Capacity
- WV3 features a 13.1-km swath width (at nadir) with the ability to collect up to 680,000 square kilometer (sq km) of high-resolution data per day.
- 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.
