Global DEMs vary from one to another: an evaluation of newly released Copernicus, NASA and AW3D30 DEM on selected terrains of China using ICESat-2 altimetry data

International Journal of Digital Earth, 2022
A good understanding of the quality of digital elevation model (DEM) is a perquisite for various applications. This study investigates the accuracy of three most recently released 1-arcsec global DEMs (GDEMs, Copernicus, NASA and AW3D30) in five selected

Topographic Analysis of Landslide Distribution Using AW3D30 Data

Geosciences, 2020
Landslides cause serious damage to society, and some occur as reactivations of old landslides in response to earthquakes and/or rainfall. Landslide distributions are therefore useful when siting engineering projects such as road and tunnel constructions.

Synching with seasonality: Predicting roe deer parturition phenology across its distributional range. [PDF]

J Anim Ecol
Using an unprecedentedly large data set on roe deer parturition dates, our study shows that elevation and Colwell's metrics of environmental predictability enhance the prediction of the timing of parturition across Europe, compared to using latitude and elevation alone.
