Assessment of FABDEM on the Different Types of Topographic Regions in India Using Differential GPS Data

Engineering Proceedings, 2022
The Forest and Buildings removed Copernicus DEM (FABDEM) represents a global DEM generated through the elimination of height biases arising due to buildings and trees in the Copernicus global 30 m (GLO-30) digital elevation model (DEM). Copernicus GLO-30

Kvalitetsundersökning av de globala höjdmodellerna Copernicus GLO-30 DEM och FABDEM över tre områden i Sverige

, 2022
Höjddata är fundamentala inom en mängd applikationer. Genom att skapa en digital höjdmodell (DEM), d.v.s. en matematisk modell av terrängens fysiska form, kan höjddata nyttjas på ett effektivt sätt.

Applicability Assessment of Multi-Source DEM-Assisted InSAR Deformation Monitoring Considering Two Topographical Features

Land, 2023
The high-precision digital elevation model (DEM) is of great significance for improving the accuracy of InSAR deformation monitoring. In today’s free opening of multi-source DEM, there is no consensus on how to select suitable DEMs to assist InSAR in ...

Validation of FABDEM, a global bare-earth elevation model, against UAV-lidar derived elevation in a complex forested mountain catchment

Environmental Research Communications, 2023
Space-based, global-extent digital elevation models (DEMs) are key inputs to many Earth sciences applications. However, many of these applications require the use of a ‘bare-Earth’ DEM versus a digital surface model (DSM), the latter of which may include

ON THE EFFECT OF DEM QUALITY FOR LANDSLIDE SUSCEPTIBILITY MAPPING [PDF]

ISPRS Annals of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2022
Generating precise and up-to-date landslide susceptibility maps (LSMs) in landslide-prone areas is important to identify hazard potential in the future. The data quality and the method selection affect the accuracy of the LSMs.
