Table 3 Integrated relationships of band index/ ratio / combination used for Estimation of SSC (mg/L).
Relationships | x | y | R2 | |
|---|---|---|---|---|
Spectral Integration of R-NDSSI | y = -2.535 × 2 + 1.8752x + 0.1739 | R-NDSSI Sentinel −2 | Estimated R-NDSSI Spectro | 0.81 |
y = 289.64 × 2 − 380.19x + 143.95 | Estimated R-NDSSI Spectro | Estimated SSC (mg/L) | 0.78 | |
Spectral Integration of (Red + Green + Red Edge 1)/3 | y = 0.0105 × 2 + 0.1825x + 0.5068 | (Red + Green + Red Edge 1)/3 Sentinel − 2 | Estimated (Red + Green + Red Edge 1)/3 Spectro | 0.87 |
y = -3.9145 × 2 + 48.303x − 24.774 | Estimated (Red + Green + Red Edge 1)/3 Spectro | Estimated SSC (mg/L) | 0.82 | |
Spectral Integration of (Green × Red Edge 1)/Red | y = 0.4241 × 0.8319 | [(Green × Red Edge 1)/Red Sentinel – 2 | (Green × Red Edge 1)/Red Spectro | 0.75 |
y = -1.9781 × 2 + 33.124x − 15.289 | (Green × Red Edge 1)/Red Spectro | Estimated SSC (mg/L) | 0.86 |
