Eyes on Earth Episode 84 - Hurricane Disturbance Mapping
When disaster strikes, near-real-time images of its effects can be invaluable. In this episode of Eyes on Earth, we learn about how a newly developed system using the Harmonized Landsat Sentinel-2 dataset and artificial intelligence was put to the test when Hurricane Ian tore through Florida in late September 2022. By comparing pre-storm and post-storm imagery, the system quickly flagged anomalies statewide such as brightness, which could indicate exposed sand or bare land after a hurricane. Harmonized Landsat Sentinel-2 data is available through the Land Processes Distributed Active Archive Center, or LP DAAC for short, located at EROS, which is also home to the entire Landsat archive.
