2D and 3D landscape metrics in high mountains - a case study from the Polish Tatra Mountains

TL;DRAbstract

Traditionally, landscape metrics are computed in 2D – using projection of the spatial units on the reference plain. In recent years, the 3D approach, which uses true surface geometries, is developed. The aim of the paper is to compare values of 2D and 3D landscape metrics in high mountains, on the example of Morskie Oko catchment in the Polish Tatra Mountains. The calculations show that the metrics may differ significantly and that there is a strong correlation between size of the discrepancy and the surface slope.
