Calculate Transformed Chlorophyll Absorption in Reflectance Index Over Optimised Soil-Adjusted Vegetation Index
1 | TCARI_over_OSAVI(df, outp_fname = NULL, ...)
|
df |
A data frame where columns represent measurements in a single wavelength, and columns are named following Quantalab's conventions |
outp_fname |
In case the input is raster data, this is the optional output filename to write the result to |
... |
Arguments to be passed to get_band_of_wavelength, particularly band_txt, splitter, and i. |
A vector with the value of the index
TCARI is mostly pigment related but, at least in crops, is also sensitive to structure. Hence TCARI/OSAVI estimates chlorohyll content better in eg mais crops over a range of LAI values
