ASTER GLOBAL DEM VERSION 3, AND NEW ASTER WATER BODY DATASET [PDF]

The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2016
In 2016, the US/Japan ASTER (Advanced Spaceborne Thermal Emission and Reflection Radiometer) project released Version 3 of the Global DEM (GDEM). This 30 m DEM covers the earth’s surface from 82N to 82S, and improves on two earlier versions by ...

Quality assessment of open sourced digital elevation models in southeast coast of India

Egyptian Journal of Remote Sensing and Space Sciences, 2021
Digital elevation model (DEM) provides elevation values of the terrain. At present several open source DEMs are available and its vertical accuracy varies from place to place. The present study assessed the vertical accuracy of 1 arc-sec data of Advanced

Global digital elevation model (GDEM) product generation by correcting ASTER GDEM elevation with ICESat-2 altimeter data [PDF]

Earth System Science Data
Advancements in scientific inquiry and practical applications have created a higher demand for the accuracy of global digital elevation models (GDEMs), especially for GDEMs whose main data source is optical imagery. To address this challenge, integrating

Local and Tele‐Coupling Coordination Relationships Between Urban Resilience and Ecosystem Health in the Beijing‐Tianjin‐Hebei Region and Analysis of Their Influencing Factors

Land Degradation &Development, EarlyView.
ABSTRACT Urban resilience and ecosystem health are essential foundations for regional sustainable development, yet their coupled and coordinated relationships remain insufficiently explored at the urban‐agglomeration scale. Taking the 13 prefecture‐level cities in the Beijing‐Tianjin‐Hebei urban agglomeration as the study area and using panel data for ...

Revealing Dust Source Changes in East Asia From Past to Future: An Interpretable Deep Learning Approach

Land Degradation &Development, EarlyView.
ABSTRACT Aeolian dust source areas are controlled by climate and human activities and are closely associated with land degradation, yet their long‐term evolution under global warming remains insufficiently quantified. An integrated framework that couples a U‐Net segmentation model with Shapley Additive Explanations (SHAP) was built to map and attribute

Fine‐scale spatio‐temporal niche partitioning enables coexistence of wild ungulates and livestock in a resource‐limited Himalayan landscape, India

Wildlife Biology, EarlyView.
Understanding how wild ungulates share space with domestic livestock is central to conservation planning in Himalayan multi‐use landscapes. This study focuses on multi‐axis niche relationships among six wild ungulates: hangul Cervus hanglu hanglu, Kashmir musk deer Moschus cupreus, Himalayan goral Naemorhedus goral, kashmir markhor Capra falconeri ...

Productivity and Human Disturbance Shape Contrasting Distribution Patterns of Core and Occasional Bird Species in a Subtropical Forest Reserve in Southern China

Integrative Zoology, EarlyView.
Bird diversity hot spots in a recovering subtropical forest do not align with protected area zoning, instead occurring in experimental zones with low‐intensity human activity. This mismatch is driven by contrasting responses: Abundant core species are supported by productivity, while many species of low frequency are attracted to the habitat ...
