Measurement data for the article Uncertainty caused by incidence angle effects on vegetation spectral indices from multispectral lidar, including angle and incidence data and resulting model fitting parameters.
| Variable | Description |
|---|---|
| Measurements | 10×1 cell array of matrices. Each cell array elements contains the measurements for a single sample. For the matrices, the first column contains the measurement angle, while the remaining 8 columns contain the measured intensities corresponding to the angle. One column for each of the 8 laser wavelengths. |
| DataNames | Descriptive names for the 10 leaf and needle samples. |
| WaveLengths | Wavelengths for the measurements. 3 different sets (rows) were used, with minor differences. |
| WaveIndex | Vector of indices for the WaveLengths matrix, describing which row of wavelength was used for which sample. |
| KD | Lambertian-Beckmann fitting results. KD(i,j) is the fraction of the diffuse component (kd) for the sample i and wavelength j. |
| M | Lambertian-Beckmann fitting results. M(i,j) is the surface roughness parameter (m) for the sample i and wavelength j. |
| FourierCoeffs | Parameters for the second-order Fourier series fitting. FourierCoeffs(i,j,:) contains the parameters for the Fourier series fitted to sample i and wavelength j. In order the parameters are a0, a1, b1, a2, b2, w as returned by the fit-function of MATLAB. |
