# Hs—Hill Size > [!note] Cette page n'est pas encore traduite et s'affiche en anglais. This is the average cross-sectional area of the hills within the analyzed cells, measured in square millimetres [mm²]. The algorithm detects the cross-sections of the hills and calculates the mean area. The threshold height used to define the cross-sections is parameterized, meaning it can be adjusted based on specific analysis requirements. Understanding hill size helps in evaluating the distribution and prominence of these elevated features.
