NASA's OPERA Land Surface Disturbance Alert product (Version 1) maps vegetation and generic disturbance alerts at 30-meter spatial resolution. It is derived from harmonized data collected by Landsat 8/9 and Sentinel-2A/B/C satellites, providing high temporal frequency for detecting land changes. The product contains 19 layers in Cloud Optimized GeoTIFF format, including disturbance status, confidence, date, and vegetation cover metrics.
Contains modified Copernicus Sentinel data (2020-2025). Users must review Section 5 of the Algorithm Theoretical Basis Document (ATBD) for additional usage constraints.
