The bathymetric band combination (4,3,1) uses the red (4), green (3), and coastal bands to peak into water. The coastal band is useful in coastal, bathymetric, and aerosol studies because it reflects blues and violets. This band combination is good for estimating suspended sediment in the...
This derived SST can be used for monitoring salinity variation, chl-a accumulation, coral bleaching, coastal plumes, thermal pollution by factories and power plants, and so on. It is noticed that the Landsat 8 TIRS image with the combination of the visible and near-infrared (VNIR) and short...
Besides, the Sobol' sensitivity analysis was applied to determine the best bands combination from the performance standpoint. The results of the Sobol' sensitivity analysis revealed that band 1-Coastal/Aerosol (0.433-0.453 mu m), band 2-Blue (0.450-0.515 mu m) and band 3-Green (0.525-0. ...

We find the highest correlation between SSCs and Landsat-8 surface reflectance by using the red + NIR band combination (r2 = 0.76). The highest correlation between SSCs and in situ field spectrometer measurements is in the 740–800 nm wavelength range (r2 = 0.85), a spectral range not cur...
�Clear, deep water will be very dark in this combination, if the water is shallow or contains sediments it would appear as shades of lighter blue.�For vegetation studies, the addition of the Mid-IR band increases sensitivity of detecting various stages of plant growth or stress; however...
In the present investigation, lineament mapping was first conducted using Landsat-8 OLI/SRTM images. To enhance the image, various techniques were used, including band combination (BC), PCA, color composition (CC), and spatial directional filtering (SDF). The boundaries between the light and dark...
This and cloud and optically thick smoke obscuration mean that near-daily satellite observations, such as provided by MODIS or by combination of data from the Landsat and Sentinel-2 sensors, are required to reliably map on a systematic basis the area burned and the date of burning (Giglio et...
