This is the same information as in the table above but broken down by each sensor. On board Landsat-8, OLI generates 9 spectral bands (Band 1 to 9).Landsat 8 bands from the OLI sensorare coastal, blue, green, red, NIR, SWIR-1, SWIR-2 and cirrus. These 8 bands have a ground res...

Band 9 Image of the desert to the west of Fayum, Egypt.Band 10 and 11 are Thermal InfraRed bands and they can see heat. Unlike meteorological stations which can monitor the air temperature, these bands combination reflects the temperature mapping of the ground surface which is usually hotter ...

In addition, Sentinel-2 exhibits significant multivariety classification ability compared to the pan-sharpened Landsat-9, despite the improved resolution of the latter. Lastly, the best classification performances were recorded for the combination Sentinel-2/SVM classifier. At last, machine learning ...
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...
Computes a simple cloud-likelihood score in the range [0,100] using a combination of brightness, temperature, and NDSI. This is not a robust cloud detector, and is intended mainly to compare multiple looks at the same point for *relative* cloud likelihood. ...
被引量: 9发表: 2017年 A Harmonized Landsat-Sentinel-2 Surface Reflectance product: a resource for Agricultural Monitoring The combination of Landsat and Sentinel-2 data offers a unique opportunity to observe globally the land every 2-3 days at medium (<30m) spatial resolution... JG Masek,M ...
Results showed that the B456 brand which OIF value was 27.842 was the best band combination among 35 kinds of combinations of 7 bands.Qualitative and quantitative accuracy assessment before and after merging image showed that each index of OLI image was the dominated for PCA algorithm, which had...
Here, the OIF calculation rendered the combination of bands corresponding to short-wavelength infrared (6), visible red (4), and visible violet-blue (1) as optimal for an RGB colour composite. 3.3.2 Band ratioing Band ratioing is a common spectral enhancement technique used to highlight ...
