)
Image_Path |
character. Path of the image to be processed |
Mask_Path |
character. Path of the mask corresponding to the image |
Output_Dir |
character. Path for output directory |
TypePCA |
character. Type of PCA: choose either "PCA" or "SPCA" |
NDVI_Thresh |
numeric. NDVI threshold applied to produce a mask (select pixels with NDVI>NDVI_Thresh) |
Blue_Thresh |
numeric. Blue threshold applied to produce a mask (select pixels with Blue refl < Blue_Thresh –> filter clouds) refl expected between 0 and 10000 |
NIR_Thresh |
numeric. NIR threshold applied to produce a mask (select pixels with NIR refl > NIR_Thresh) refl expected between 0 and 10000 |
Blue |
numeric. central wavelength corresponding to the blue spectral band (in nanometers) |
Red |
numeric. central wavelength corresponding to the red spectral band (in nanometers) |
NIR |
numeric. central wavelength corresponding to the NIR spectral band (in nanometers) |
MaskPath = updated mask file
