## Long Description

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.

## Parameters

- [param] -out <string> Radiometric indices output image. Mandatory: True. Default Value: ""
- [param] -ram <int32> Available memory for processing (in MB). Mandatory: False. Default Value: "128"
- [param] -channels <string> Channels selection. Mandatory: True. Default Value: "0"
