Vegetation Indices
Mavis can be used to calculate vegetation indices for dual and single camera setups.

The following indices can be derived:
- DVI, Difference Vegetation Index, Tucker, 1979
- NDVI, Normalized Difference Vegetation Index, Rouse et al., 1973
- GNDVI, Normalized Difference Vegetation Index, Rouse et al., 1973
- SAVI, Soil Adjusted Vegetation Index, Huete, 1988
- OSAVI, Optimized Soil Adjusted Vegetation Index, Rondeaux et al., 1996
- MSAVI2, Modified Soil Adjusted Vegetation Index, Qi et al., 1994
For single camera setups the filter type can be selected depending on the camera setup. Blue is for filters like the Schott BG3 or the Event38 NGB filter glass. Select Red if you are using a Wratten 25, a MidOpt 660/850 dual band or similar filters.
All indices are provided as TIF files with a specific color scheme applied as well as raw datasets in SAGA GIS grid format for further processing.
