Comparison settings of the 5 m DEM and the summary of statistics
Source publication
DEM generation since the turn of 21th century, predominantly relied upon space-borne imagery captured with active or passive sensors. However, Türkiye recently managed just that utilizing stereo captured air photography. Considerably high resolution national Digital Elevation Model, 5 m spatial, was the resampled version of the originally built 0.3...

Context 1
... (9; 10) stated that the errors in a DEM may not necessarily conform to a normal distribution, we assumed that the vertical errors were normally distributed (11). GNSS records were initially categorized in 5 different settings, and only in site 2 were both MSE and MAE above 3 m, obviously raising the overall results above 2 m for both error metrics (Table 1). Although elevation range was greater in site 4, the reason that site 2 scored the highest in error metrics was because of the distribution of those records to the terrain (Figure 1). ...
