General InformationTo use this application, first select either the NDVI Explorer or the Burned Area Explorer from the tabs below. Then select your project area and filters in the left panel and click Generate Figure. Hover over a tab for a short description or expand this section for more information.
What is NDVI?
The NDVI Explorer uses the Normalised Difference Vegetation Index (NDVI) to monitor vegetation health over time. NDVI values range from −1 to 1, with higher values indicating healthy vegetation and lower values indicating stressed vegetation or bare surfaces.
Which data source should I use?How to use this section
- NDVI Delta Map — Use the Annual Change view to see spatially where gains and losses are occurring within the project area.
- NDVI Land Cover Explorer — Drill down by land cover class to identify which class (Trees, Crops, Rangeland etc.) is driving any trend you observed.
- NDVI Time Series — Use this view to analyze the selected year's vegetation health compared to historic trends for your area.
What is the Burned Area Explorer?
The Burned Area Explorer uses aggregate satellige image information to identify the so-called burn scar (blackened soil after a fire) and its starting date. It is based on MODIS-data at a 500m resolution.
How to use this section- Burned Area Map Explorer — Use the Monthly View to locate fires, the Interactive Map to explore fire locations, and the Fire Return Period to identify frequently burned areas.
- Burned Area Time Series — Use the Monthly View to compare the selected year with historical trends, and the Annual View to compare burned area across years and analyse fire timing.
