Europe's free satellite service just made it easier to track wildfires
TL;DR
Europe's Copernicus Browser has introduced a new wildfire visualization layer, enhancing the tracking of wildfires using Sentinel-2 satellite imagery. This tool allows users to easily identify active fires and burned areas.
✦ Why It Matters
Start using the Copernicus Browser today to monitor wildfire activity in your area.
Key Takeaways
- Access the Copernicus Browser for free satellite imagery.
- Utilize the new wildfire layer for real-time tracking.
- Explore multi-spectral imaging capabilities for detailed analysis.
- Implement the JavaScript script for custom visualization needs.
How It Works
The wildfire visualization layer combines multiple spectral bands from Sentinel-2 imagery. It uses the red visible light band to identify active fires, the near-infrared band to differentiate between healthy and burned vegetation, and the short-wave infrared band to assess soil moisture levels, revealing burned landscapes.
