3.3 Principal component analysis of Landsat imagery The Landsat 8 imagery of the study area acquired on 2019-04-05 was used for deriving the correlation between the heavy metal concentration and the reflectance values. Empirical models developed using reflectance calibrated Landsat imageries and water ...
本研究采用美国陆地卫星计划(Landsat)的第八颗卫星(Landsat8)、开源地图(open street map,OSM)、可见光红外成像辐射仪(visible infrared imaging radiometer,VIIRS)-日夜波段(day/night band,DNB)夜间灯光数据、第七次人口普查数据(含乡镇街道级别)、Worldpop数据以及行政边界数据。由于使用的数据源不同,因此,首先要对...
Active fire detection in satellite imagery is of critical importance to the management of environmental conservation policies, supporting decision-making and law enforcement. This is a well established field, with many techniques being proposed over the years, usually based on pixel or region-level ...

The panchromatic band spans are a longer range of wavelengths and can generate 15m panchromatic images. By pansharpening imagery with the panchromatic band, you can sharpen your imagery producing a crisper product. Vegetation Index The vegetation index leverages the properties of the red (which vegeta...
The study was conducted using Landsat 8 OLI multispectral imagery covering the areas of Andaman Is, Bhitarkanika and Indian Sundarbans. Three bands (Red Band, Green Band and Near Infra-Red Band) out of the eight bands (Coastal Aerosol, Blue, Green, Red, NIR, SWIR 1, SWIR 2 and Cirrus)...
