Layers
- True Color
- False Color Bands 8, 4, 3
- SWIR Short Wave Infrared (Bands 12,8A,4) Burn scar and fire detection.
- NDVI Normalized Difference Vegetation Index Indicator for vegetation health, where healthy vegetation generally falls between values of 0.3 to 0.8.
- EVI Enhanced Vegetation Index Indicator for vegetation health for dense canopies, where healthy vegetation generally falls between values of 0.2 to 0.8.
- SAVI Soil-adjusted Vegetation Index Indication of plant growth vigour A vegetation index that less affected by exposed soil background reflectace (e.g. when crops are grown in rows and unplanted soils are exposed to the satellite) and less succeptible to saturation (e.g. when crops are fully grown and form a closed canopy).
- AVI Advanced Vegetation Index Indicator for vegetation health. Similar to NDVI, but reacts more sensitively to vegetation quantity and is able to highlight subtle differences in canopy density.
- SRI Simple Ratio Index Vegetation Health, where healthy vegetation generally falls between values of 2 to 8.
- TVI Triangular Vegetation Index Biomass estimation for dense canopies.
- NDRE Normalized Difference Red Edge Index
- LAI (EVI) Leaf Area Index (Enhanced Vegetation Index)
- BSI Bare Soil Index.
- NDWI 20m Normalized Difference Water Index (Gao, 1996) Moisture condition of vegetation canopies, drought stress indicator.
- NDMI Normalized Difference Moisture Index. Indication of moisture content.
- MSI Moisture Stress Index This index is inverted relative to other water vegetation indices; higher values indicate greater water stress and less water content. The common range for green vegetation is 0.4 to 2.
- MNDWI Modified Normalized Difference Water Index Water body mapping.
- True Color (30m)
- False Color (30m)
- SWIR Short Wave Infrared (Bands 7,5,4) Burn scar and fire detection.
- NDVI Normalized Difference Vegetation Index (30m)
- EVI Enhanced Vegetation Index Indicate total chlorophyll content of the leaves.
- SRI Simple Ratio Index Vegetation Health, where healthy vegetation generally falls between values of 2 to 8.
- NRI Nitrogen Reflectance Index

About S2 Viewer beta
The S2 Viewer beta is an interactive platform to view and analyse data from the Sentinel-2 and Landsat 8 satellites.
The platform provides a range of multispectral indices, derived from the satellite data, to assist and inform users with the monitoring of various aspects of crop and plant health.
