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

• Input Image (in): Input image

• Output Image (out): Radiometric indices output image

• Available RAM (Mb) (ram): Available memory for processing (in MB)

• Channels selection (channels): Channels selection

  • Blue Channel (channels.blue): Blue channel index

  • Green Channel (channels.green): Green channel index

  • Red Channel (channels.red): Red channel index

  • NIR Channel (channels.nir): NIR channel index

  • Mir Channel (channels.mir): Mir channel index




• Available Radiometric Indices (list): List of available radiometric indices with their relevant channels in brackets:
  Vegetation:NDVI - Normalized difference vegetation index (Red, NIR)
  Vegetation:TNDVI - Transformed normalized difference vegetation index (Red, NIR)
  Vegetation:RVI - Ratio vegetation index (Red, NIR)
  Vegetation:SAVI - Soil adjusted vegetation index (Red, NIR)
  Vegetation:TSAVI - Transformed soil adjusted vegetation index (Red, NIR)
  Vegetation:MSAVI - Modified soil adjusted vegetation index (Red, NIR)
  Vegetation:MSAVI2 - Modified soil adjusted vegetation index 2 (Red, NIR)
  Vegetation:GEMI - Global environment monitoring index (Red, NIR)
  Vegetation:IPVI - Infrared percentage vegetation index (Red, NIR)
  
  Water:NDWI - Normalized difference water index (Gao 1996) (NIR, MIR)
  Water:NDWI2 - Normalized difference water index (Mc Feeters 1996) (Green, NIR)
  Water:MNDWI - Modified normalized difference water index (Xu 2006) (Green, MIR)
  Water:NDPI - Normalized difference pond index (Lacaux et al.) (MIR, Green)
  Water:NDTI - Normalized difference turbidity index (Lacaux et al.) (Red, Green)
  
  Soil:RI - Redness index (Red, Green)
  Soil:CI - Color index (Red, Green)
  Soil:BI - Brightness index (Red, Green)
  Soil:BI2 - Brightness index 2 (NIR, Red, Green)
