This study investigates the accuracy of various DEMs (SRTM DEM, ASTER GDEM, and ALOS PALSAR DEM) for area designing Pskom water reservoir (recommended to construction in River, Tashkent region. are compared using Global Mapper application selection Ground Control Points (GCP). The RMSE we calculate is most easily interpreted statistic as square root mean error because it has same units quantity...

Since the end of 20th century, use geographic information systems and digital elevation models has reduced time required for improved quality morphometric analysis relief within river basins. However, researchers are constantly faced with problem choosing most accurate suitable terrain model their task. Many global, regional, local available. In this study, we comparatively analyzed accuracy AS...

In many arid mountains, dwarf shrubs represent the most important fodder and firewood resources; therefore, they are intensely used. For the Eastern Pamirs (Tajikistan), they are assumed to be overused. However, empirical evidence on this issue is lacking. We aim to provide a method capable of mapping vegetation in this mountain desert. We used random forest models based on remote sensing data ...

Drainage basin/watershed analysis based on morphometric parameters has an essential role in watershed management and planning. Reliable delineation of watersheds drainage networks is critical for hydrological geomorphological studies. Since access to high-resolution digital elevation models (DEMs) surface (DSMs) costly, many researchers need evaluate low-resolution open-source products. Several...
