The vertical accuracy of global DEMs is more affected by terrain roughness.
“Since the vertical accuracy of global DEMs is more affected by the terrain roughness(Mukherjee et al. 2013;Szabó, Singh, and Szabó 2015;Varga and Bašić 2015;Jain et al. 2017), its influence on DEMs vertical accuracy was analyzed.”
From Vertical accuracy evaluation of freely available latest high-resolution (30 m) global digital elevation models over Cameroon (Central Africa) with GPS/leveling ground control points. (2019) · cites this paper as Szabó, Singh, and Szabó 2015

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
