Question:

A remote sensing instrument measures only in Green, Red and Near-Infrared frequency bands. The remote sensing index/indices that CANNOT be derived using data of this instrument is/are:

Show Hint

EVI and ARVI require the Blue band. Without it, only indices based on Red and NIR like NDVI and SAVI can be computed.

The Correct Option is B, D

Solution and Explanation

NDVI and SAVI require only Red and Near-Infrared bands, which are available. ARVI requires the Blue band, and EVI uses Blue for atmospheric resistance and soil adjustment. Since Blue is not available, ARVI and EVI cannot be calculated.
