A primary goal of many remote sensing projects is to characterize the type, size and condition of vegetation present within a region. By combining data from two or more spectral bands we obtain what is commonly known as a vegetation index (VI), which enhances the vegetation signal, while minimizing solar irradiance and soil background effects. This study addresses the computation of Normalized ...

Aerosol Optical Thickness (AOT) is an important parameter in Radiative Transfer Models (RTMs) used for atmospheric correction of remotely-sensed data. It is often estimated from horizontal visibility measurements by use of the Koschmieder formula or other related methods built into RTMs. This paper assesses the accuracy of this estimation, in the context of atmospheric correction, by comparing ...

Annualy, SARS occupy a leading position in terms of morbidity and the magnitude economic damage caused both world Russian Federation. Currently, most widespread pandemics are by influenza A (H1N1) pdm09 virus new SARS-CoV-2 coronavirus, which common ecological niche require studying manifestations epidemic process ARVI for further development measures to improve epidemiological surveillance thi...

Accurate and up-to-date mapping and monitoring of rubber plantations is challenging. In this study, we presented a simple method for rapidly and accurately mapping rubber plantations in the Xishuangbanna region of southwest China using phenology-based vegetation index differencing. Temporal profiles of the Normalized Difference Vegetation Index (NDVI), Enhanced Vegetation Index (EVI), Atmospher...
