%description
The developed function generates soil salinity indices using satellite
data, utilizing multiple spectral bands such as Blue, Green, Red,
Near-Infrared (NIR), and Shortwave Infrared (SWIR1, SWIR2). It computes 24
different salinity indices crucial for monitoring and analyzing
salt-affected soils efficiently. For more details see, Rani, et al.
(2022). <DOI: 10.1007/s12517-022-09682-3>. One of the key features of the
developed function is its flexibility. Users can provide any combination
of the required spectral bands, and the function will automatically
calculate only the relevant indices based on the available data. This
dynamic capability ensures that users can maximize the utility of their
data without the need for all spectral bands, making the package versatile
and user-friendly. Outputs are provided as GeoTIFF file format,
facilitating easy integration with GIS workflows.
