Quantitative geomorphic research depends on accurate topographic data often collected via
remote sensing. Lidar, and photogrammetric methods like structure-from-motion, provide the …

Several global digital elevation models (DEMs) have been developed in the last two
decades. The most recent addition to the family of global DEMs is the TanDEM-X DEM. The …

Open‐source, satellite‐based digital elevation models (DEMs) are widely used for flood
modeling. However, studies on effectiveness of these DEMs in depicting local‐level flood …

In this contribution, we assess the vertical accuracy of the Advanced Land Observing
Satellite (ALOS) World 3D 30 m (AW3D30) digital elevation model (DEM) using the runway …

From an extensive search of papers related to the comparison of Global Digital Elevation
Models (hereinafter GDEMs), an analysis is carried out that aims to answer several …

Abstract Glacial Lake Outburst Floods (GLOFs) have become increasingly common over the
past century in response to climate change, posing risks for human activities in many …

Much of geomorphology depends on accurate topographic data. Satellites have transformed
our ability to capture such data from planetary surfaces over the last 2 decades. Truly global …

Many biochemical processes and dynamics are strongly controlled by terrain topography,
making digital elevation models (DEM) a fundamental dataset for a range of applications …

The floods that struck lower Tagus valley in February 1979 correspond to the most intense
floods in this river and affected the largest number of people in a river flow event in Portugal …

Many geoscientific computations are directly influenced by the resolution and accuracy of
digital elevation models (DEMs). Therefore, knowledge about the accuracy of DEMs is …
