The primary goal of the German TanDEM-X mission is the generation of a highly accurate
and global Digital Elevation Model (DEM) with global accuracies of at least 10 m absolute …

Abstract Digital Elevation Model is imperative to many earth surface process analyses. In
this study, the quality of DEMs acquired by SRTM ver. 3 and ASTER ver. 2 is evaluated. The …

This work assesses the vertical accuracy of eight Digital Surface Models (DSMs) currently
available for Mexico (LiDAR, ALOS AW3D30 V2 and V3, ASTER GDEM V2 and V3, SRTM …

Elevation data are critical for assessments of sea-level rise (SLR) and coastal flooding
exposure. Previous research has demonstrated that the quality of data used in elevation …

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 development of geospatial technologies has opened a new era in terms of data
collection techniques and analysis procedures. Digital elevation models as 3D visualization …

The mixed additive and multiplicative random error model is a combination of the additive
error random model and multiplicative random error model. Weakness is an attribute of the …

Coastal areas are currently exposed to numerous hazards exacerbated by climate change,
including erosion, flooding, storm surges, and other sea level rise phenomena …

Delineation of Glaciers is a challenging task in the Himalaya due to its complex topography,
cloud cover, seasonal snow cover, hillshade, debris cover. Glacio-hydrological studies …

One of the main concerns during digital elevation model (DEM) evaluation is the number of
ground control points (GCP). Accordingly, in this paper, a new method is proposed for …
