NDBI

Parameter Setting

  • Input hyperspectral image data: Input the hyperspectral image data file. The format supports tif, tiff, img, dat. The data must have wavelength information.
  • Band: Select the band participating in the calculation and can automatically match the band according to the wavelength.
  • ROI: After selection, only the minimum external rectangle in the ROI area is calculated exponentially.
  • Mask: Only the effective area of ​​the mask is calculated exponentially after selection.
  • Output path: The generated tif path.
