| Name | Type | Complete name | Description | |
|---|---|---|---|---|
| 1. | BRI | Vegetation | Browning Reflectance Index | BRI measures the changes which plants experience during tissue browning and necrotization. Studies show that reflectance spectra experience the most significant changes in the green (near 550 nm) and NIR spectral regions, whereas the red band of Chlorophyll absorption remains much less affected. |
| 2. | NDSI | Snow | Normalized Diference Snow Index | The normalized difference between spectral bands green (G) and the shortwave infrared (SWIR). The NDSI is particularly useful for separating snow from vegetation, soils, and lithology endmembers. |
| 3. | TCI | Other | True Color Image | True Color imagery was designed to display the Earth in colors similar to what we might see with our own eyes. The product is primarily a combination of the three channels that are sensitive to the red, green, and blue visible light. |
| 4. | GVMI | Vegetation | Global Vegetation Moisture Index | Index suitable for retrieving vegetation water content when the LAI is equal to or greater than 2. For sparsely vegetated area, where LAI is less than 2, further research is required to understand the role of soil effects on reflectance measured in the all-optical spectrum |
| 5. | Classifier | Other | Land Cover Classifier | Land Cover Classification based on the NDVI index in the following classes: Water, Non-vegetation and Vegetation. |
| 6. | EVI | Vegetation | Enhanced Vegetation Index | The enhanced vegetation index (EVI) is an 'optimized' vegetation index designed to enhance the vegetation signal with improved sensitivity in high biomass regions and improved vegetation monitoring through a de-coupling of the canopy background signal and a reduction in atmosphere influences. |
| 7. | EVI2 | Vegetation | Two-Band Enhanced Vegetation Index | Two-Band adaptation of EVI (removing the blue band) for greater sensors support. |
| 8. | NDWI | Water | Normalized Difference Water Index | The visible green wavelengths maximize the typical reflectance of the water surface. The near-infrared wavelengths maximize the high reflectance of terrestrial vegetation and soil features, while minimizing the low reflectance of water features. The result of the NDWI equation is positive values for water features and negative ones (or zero) for soil and terrestrial vegetation. |
| 9. | MNDWI | Water | Modification of Normalised Difference Water Index | Modification of NDWI where the contrast between water and built‐up land of the MNDWI will be considerably enlarged owing to increasing values of water feature and decreasing values of built‐up land from positive down to negative |
| 10. | OSAVI | Vegetation | Optimized Soil Adjusted Vegetation Index | Derivative from NDVI that uses a transformation technique to minimize soil brightness influences from spectral vegetation indices involving red and near-infrared (NIR) wavelengths. |
| 11. | NDVI | Vegetation | Normalized Diference Vegetation Index | Simple graphical indicator that can be used to analyze remote sensing measurements assessing whether or not the target being observed contains live green vegetation. |
| 12. | NDYI | Vegetation | Normalized Diference Yellow Index | Captures the increasing yellowness of vegetation due to flowering, originally develop to capture the phenological development of oilseed rape flowering. |
| 13. | NDRE | Vegetation | Normalized Difference Red-Edge | Is a method of measuring the amount of chlorophyll in the plants. The best timing to apply NDRE is mid-to-late growing season when the plants are mature and ready to be harvested. At this point, other indices would be less effective to use. |
| 14. | BSI | Soil | Bare Soil Index | Indicator that combines blue, red, near infrared and short wave infrared spectral bands to capture soil variations. These spectral bands are used in a normalized manner. The short wave infrared and the red spectral bands are used to quantify the soil mineral composition, while the blue and the near infrared spectral bands are used to enhance the presence of vegetation. |
