“…Tools utilised by scholars to assess geodiversity were varied but mostly included spatial analytical approaches such as the grid system approach (Araujo and Pereira, 2018; Bétard and Peulvast, 2019; Pereira et al, 2013; Soms, 2017), digital elevation model (Kot, 2018; Pellitero et al, 2011; Scarsi et al, 2019), rasterisation (Melelli et al, 2017; Pellitero et al, 2015; Stepišnik and Trenchovska, 2018) or the geodiversity index (Chelariu and Hapciuc, 2017; Ilic et al, 2016; Manosso and de Nobrega, 2016; Ozsahin, 2017; Serrano et al, 2009) (Figure S2A). In the years following 2015, new spatial analytical techniques were proposed to quantify geodiversity, such as the proposal of a virtual globe flight simulator approach (Martinez-Grana et al, 2015) or the proposal of centroid analysis as an alternative to the commonly used grid system approach in geodiversity assessments (Nobre da Silva et al, 2019).…”
