To correct the effect of vegetation on most pixels, the adopted solution is to develop an empirical model that relates vegetation height, or the magnitude of the error vegetation causes in DEMs, to the correction.
“To correct the effect of vegetation on most pixels, the solution that has been adopted is to develop an empirical model that relates the height of the vegetation, or more precisely, the magnitude of the error that the vegetation causes in DEMs [22][23][24].”
From ANADEM: A Digital Terrain Model for South America (2024) · cites this paper as [24]
Section 2.1 describes a regression model that predicts SRTM height differences from canopy cover and terrain slope, supporting the claim that an empirical model is used to correct elevation errors. It does not use vegetation height as a model input. The Discussion reports improved agreement at 70% of SRTM grid locations in the study site, rather than establishing a solution for most pixels across DEMs generally; page numbers are unavailable in our copy.

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.
