18 interactive maps of NASA OPERA products: surface water, vegetation disturbance, SAR backscatter, and ground displacement, from 2022 to the floods and fires of 2026. Each one is a GeoLibre project that renders OPERA rasters straight from NASA GIBS or, through titiler-cmr, from the original granules in NASA CMR, the same path the plugin's Display button uses. Click a map to open it live, swipe the before-and-after pairs, or fork it on share.geolibre.app to make it your own.
