Compute radiometric indices.
This application computes radiometric indices using the relevant channels of the input image. The output is a multi band image into which each channel is one of the selected indices.
This section describes in details the parameters available for this application. Table 5.47, page 581 presents a summary of these parameters and the parameters keys to be used in command-line and programming languages. Application key is RadiometricIndices.
