Site Information
Assessment & Recommendations
↑ Back to topKey Findings
- ▸ Magnitude: 2.9% vegetation cover loss detected across 76.32 hectares
- ▸ Detection Date: Disturbance first detected on October 06, 2024
- ▸ Latest Observation: Most recent satellite data from December 30, 2024
📋 Recommended Actions
- Conduct a site inspection to confirm satellite findings and assess current conditions
- Photograph and document the extent of disturbance and any visible causes
- Determine the cause of disturbance (clearing, fire, disease, etc.)
- Update monitoring logs and notify relevant stakeholders
- Verify any required permits or authorizations if clearing was intentional
- Maintain regular satellite observation to track any further changes

This report uses vegetation disturbance data from NASA's OPERA DIST-ALERT (Observational Products for End-Users from Remote Sensing Analysis - Disturbance Alert) product. OPERA DIST-ALERT provides near real-time detection of land surface disturbances using Harmonized Landsat Sentinel-2 (HLS) data at 30-meter resolution.
