Can Optical Satellites Keep Tracking Floods When Clouds Block the View?
In brief: Landsat and Sentinel-2 can capture flood details well, but they are most vulnerable to the very condition that often accompanies major flooding: cloud cover. Rather than trying to generate a visually plausible cloud-free optical image, this study directly reconstructs whether the surface beneath the clouds is water or non-water. The researchers combined Harmonized…

From Imaging to Intelligence: How Smart Remote-Sensing Satellites Are Changing the Market
Several smart remote-sensing satellites have recently been launched in China and other countries, entering a rapidly expanding applications market and attracting growing industry attention. But what does it mean for a remote-sensing satellite to become “smart”? What benefits could onboard intelligence provide, and how might it help satellite operators reach new markets and deliver services…

Can SAR Map Floods Without Manual Labels or Threshold Tuning?
In brief: Conventional SAR-based flood mapping often runs into two obstacles: thresholds must be adjusted repeatedly by hand, while supervised learning requires large volumes of labeled data. This paper proposes Felz-CNN, also known as the adaptive unsupervised Felz-CNN segment system (AUFCS). The method first uses Felzenszwalb superpixels to divide a SAR image into many internally…

What Really Caused Pakistan’s 2022 Floods: Extreme Rainfall, Snowmelt, or Glacial Lake Outburst Floods?
In brief: Published in Remote Sensing of Environment, this study does more than use Sentinel-1 data to map Pakistan’s catastrophic 2022 floods. It seeks to answer three broader questions: How much of the country was flooded? Why was the disaster so severe? And was it worse than the major flood of 2010? The authors developed…
