Summary
The SPOT HRV XS-based Redness Index 4 (RI4XS) is a soil spectral index intended for multispectral sensing. It was introduced in 1998; its source is cited as Renaud Mathieu, Marcel Pouget, Bernard Cervelle, & Richard Escadafal (1998). Relationships between Satellite-Based Radiometric Indices Simulated Using Laboratory Reflectance Data and Typic Soil Color of an Arid Environment. Remote Sensing of Environment, 66(1). https://doi.org/10.1016/s0034-4257(98)00030-3 .
Based on the latest citation data, this index is in the 43.45th percentile overall, ranking 180 out of 313 indices with citation data.
