Publicly available Digital Elevation Models (DEM) derived from various space-based platforms (Satellite/Space Shuttle Endeavour) have had a tremendous impact on the quantification of landscape characteristics, and related processes products. The accuracy elevation data six major public domain satellite-derived (a 30 m grid size—ASTER GDEM version 3 (Ast30), SRTM (Srt30), CartoDEM V3R1 (Crt30)—a...

Geological mapping undoubtedly plays an important role in several studies and remote sensing data are of great significance geological mapping, particularly poorly mapped areas situated inaccessible regions. In the present study, Principal Component Analysis (PCA), Band Rationing (BR) Minimum Noise Fraction (MNF) algorithms applied to map lithological units extract lineaments Amezri-Amassine ar...

Anthropogenic stressors have altered the hydromorphological characteristics of rivers worldwide. Environmental guiding principles are essential for planning sustainable river restoration measures. The alpine Biya, located in Russian Altai mountains, originates from Lake Teletskoye and joins Katun near Biysk, forming Ob. Biya represents a reference system anthropogenically ‘least-disturbed’ cond...

Hongjiannao groundwater exchange was the largest desert freshwater lake in China (57.25 km2 1986). However, it shrank sharply over past 34a (1986–2019), with smallest area 31.41 2015. The objective of this study to use Landsat images, ASTER GDEM V2 data, and meteorology statistics combination water balance model calculate dynamics elements, quantify characterize interannual variations lake-grou...

Slope has obvious scale-dependent characteristics and it changes with the change in DEM resolution, which brings uncertainty to evaluation process of regional resource environment. In this paper, one typical county each six water erosion regions China was selected as sample area, respectively. Based on data ALOS DEM, ASTER GDEM SRTM different spatial resolutions, slope characteristics, such gra...

In this study, we comparison of NDVI of ground measurement, atmospheric corrected ASTER LIB data and ASTER surface reflectance product (AST07) data to evaluate the accuracy of the ATCOR software atmospheric correction of Terra/ASTER data (Jun 30, 2002), using ground radiometric measurement data (ASD's FieldSpec® Pro). Our research selected the study area Sarobetsu Marsh located in coastal area ...
