Imagery Date: 2024-10-22
Flooded acres were calculated from Sentinel-2 Surface Reflectance imagery using the Earth Engine Python API in a Jupyter notebook. Sentinel-2 (S2) is a wide-swath, high-resolution, multispectral imaging mission with a global 5-day revisit frequency.
The S2 Multispectral Instrument (MSI) samples 13 spectral bands: Visible and NIR at 10 meters, red edge and SWIR at 20 meters, and atmospheric bands at 60 meters spatial resolution. The Near Infrared (NIR) band was used to identify flooded areas by applying a threshold to isolate water.
The flooded extent estimates are validated during routine field checks throughout the seasonal flooding cycle September through April.
