A strip of 20th-century landscape woodland planted alongside a 17th to mid-18th century ancient and semi-natural (ASNW) was investigated by applied aerial spectroscopy using an unmanned vehicle (UAV) with multispectral image camera (MSI). simple classification approach normalized difference spectral index (NDSI), derived principal component analysis (PCA), enabled the identification non-native ...

Moderate Resolution Imaging Spectroradiometer (MODIS) snow cover product is one of the prevailing datasets for global monitoring, but cloud obscuration leads to discontinuity ground coverage information in spatial and temporal. To solve this problem, a novel spatial-temporal missing reconstruction model based on U-Net with partial convolutions (PU-Net) proposed recover gaps MODIS Normalized Dif...

“Snow gone” (SGN) stage is one of the critical variables that describe the start of the official forest fire season in the Canadian Province of Alberta. In this paper, our objective is to evaluate the potential of MODIS-based indices for determining the SGN stage. Those included: (i) enhanced vegetation index (EVI), (ii) normalized difference water index (NDWI) using the shortwave infrared (SWI...

snow cover area is one of the most important criteria to calculate snow melt runoff. this can have an effect on the biology of the plant and the environment of a region. using the catchment basin physical characteristic to calculate snow cover area is a conventional method, though its accuracy is not good enough. most of the useful methods in calculating snow cover area are based on satellite i...

The article presents the analysis of widespread spectral indexes results Earth remote sensing data thematic processing to reveal most representative one for applying under conditions critical increase groundwater level and salinity as well salinized soil. Long-term monitoring multispectral images LandSat-8 satellite were collected Golodnostepsky irrigation land. Sites with disturbing ameliorati...

Global warming has accelerated climate and weather changes, impacting the regional water cycle. This study assesses temporal trends of seasonal annual runoff in Chitral River Basin (CRB) its responses to climatic factors (i.e., temperature, precipitation, Normalized Difference Vegetation Index (NDVI)) oceanic indices at large scales El Nino Southern Oscillation (ENSO), Indian Ocean Dipole (IOD)...
