Coherent Markov Random Field-Based Unreliable DSM Areas Segmentation and Hierarchical Adaptive Surface Fitting for InSAR DEM Reconstruction

open access: yesSensors, 2020
A digital elevation model (DEM) can be obtained by removing ground objects, such as buildings, in a digital surface model (DSM) generated by the interferometric synthetic aperture radar (InSAR) system. However, the imaging mechanism will cause unreliable

Semiautomated classification of units in volcanic terrain based on three morphometric attributes derived from a digital elevation model (DEM)

open access: yesEarth Surface Processes and Landforms, Volume 51, Issue 5, May 2026.
The proposed method better responds to the needs of detailed cartography improving the working scale (local and regional) representation; also roughness attributes facilitate the identification of geomorphological units, and the DEM generation method enhances terrain representation.
