The image processing was performed in ArcMap and used 6-5-4 band combination for Landsat 8 to visually inspect healthy vegetation and the green spaces. The near-infrared (NIR) panchromatic band for PlanetScope was merged with Landsat 8 image using the Create Pan-Sharpened raster tool in Arc...
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...
(combination of days with heat wave and tropical night condition) has on average the most counts of emergencies/admissions in both plots. NoHD - Number of heat days (Number of heat days; i.e. days with maximum temperature ≥ 30 °C), NoHW - Number of heatwaves, i.e. number of ...
Forest aboveground biomass (AGB) plays an important role in the study of the carbon cycle and climate change in the global terrestrial ecosystem. AGB estimation based on remote sensing is an effective method for regional scale. In this study, Landsat 8 O
Forest dynamics are also highly relevant to land hydrology, climate (Band 1993, Sahin and Hall 1996, Giambelluca et al. 2000) and biodiversity (e.g. Kinnaird et al. 2003). Deforestation, for example, can have complex but often adverse impacts on biological conservation by threatening the ...
Spectral Band Combination Water Band 1, 4 & 7 / Band 1, 2 & 3 Urban Band 1,4 & 7 Farmland Band 1, 2 & 3 Forest Band 1, 4 & 7 Salt Scald Band 1, 2 & 3 Remnant Vegetation Band 1, 4 & 7 Irrigated Vegetation Band 1, 4 & 7 Terrain Feature Reflectance Response Water Bodies ...
The mutual information regression (MIR) method shows a slight increase in accuracy when considering individual sensor datasets, but its accuracy decreases when all features are taken into account for all models. Overall, the combination of features from the Landsat 8, ALOS PALSAR backscatter, and ...
Landsat 7's Enhanced Thematic Mapper Plus (ETM+)improved on the TM sensor by adding a 15 m resolution panchromatic band.Landsat's 8 Operational Land Imager (OLI) and Thermal Infrared Sensor (TIRS)further improved spectral resolution by adding an aerosol, cirrus, and additional infrared bands. ...
They occur in each of the five African biomes (tropical savanna, temperate savanna, deserts and xeric shrublands, tropical forest, Mediterranean) defined by Olson et al. (2001). This pre-existing Landsat-8 burned area reference data set has several benefits for this study: (i) they were ...
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...
