“…In order to consider fluvial processes as a relevant morphological agent, in particular on flat areas, where topographic attributes are mostly uniform and mass wasting dependent processes less significant, we considered the drainage network. The issue of unrepresented topographic features is common to other settings: Manosso et al (2021) found lower geodiversity on interfluves landforms and in areas with a homogeneous relief in Brazil, and Vörös et al (2021) had similar issues dealing with volcanic features in France.…”

Geomorphodiversity refers to the variety of landforms and morphological processes characterizing the landscape. The definition of an index to quantify geomorphodiversity is a relevant step for multiple fields of Earth sciences, since it is widely accepted that the variability of the geosphere deeply influences the diversity of the biosphere. Such an index should describe the number and type of landforms and geomorphological processes. We propose a quantitative land surface diversity index valid for Italy, considering multiple input quantities to describe geological constraints and geomorphological processes. Critical issues were the selection of moving window size for focal statistics operations, to calculate local diversity of slope, lithology, drainage density and terrain forms in individual raster maps. We compared the index with traditional geomorphological maps, in selected locations, in which information was available. Results show that a minimal set of heterogeneous data is a satisfactory approach to investigate the landscape diversity. Relating processing parameters and terrain spatial characteristics to the dataset resolution is a good choice to assess a reproducible land surface diversity index. Inclusion of drainage density allows the improvement of results in flat areas, in which other factors show trivial results. We argue that the index is relevant for land use management, assessment of ecodiversity, and it may help describing the interaction between abiotic and biotic compartments.

“…In fact, there are many examples of geodiversity quantification in which some abiotic elements are omitted [15,17,20,26]. This does not necessarily mean that the result is wrong, simply showing that their context of development is limited by a framework that depends on the conditions of the method previously shown [3,16,21,[23][24][25].…”

“…Despite its undeniable importance, geodiversity confronts various methodological challenges, largely due to its multifaceted nature, the multiple ways in which it can be studied, and the various conditioning factors of the results [14]. When comparing various authors, distinctions become evident in terms of the number and types of geodiversity classes and subclasses that they use (i.e., sets of geological elements within a region and the standard criteria used to distinguish between objects), the varying methodologies employed for index calculations, and the disparate scales and sizes of the study areas that they investigate [15][16][17][18][19][20][21][22][23][24][25][26]. Therefore, it becomes crucial to establish a well-defined methodological and informational framework to guide geodiversity assessment.…”

Geodiversity, comprising both endogenous and exogenous geological processes, plays a crucial role in shaping the structure and functionality of natural systems, alongside its substantial impact on human well-being. However, the often-overlooked interconnection between geodiversity components limits our comprehension of geosystems. In the Chinchiná River Basin (CRB) in Colombia, located in the northern Andes in South America, we established criteria to differentiate geodiversity classes, calculated indices to understand the distribution of geological elements, and discussed systemic relationships. This comprehensive approach lays the foundation for a holistic comprehension of the territory’s structure and functionality. Our findings revealed the convergence in an area of 1052 km2 of 10 rock types, 7 slope ranges, 13 landforms, 5 drainage density features, 610.4 km of faults with 9 kinematic tendencies, 5 soil orders, 5 climate types, a 3328 km surface drainage network with 7 hydrographic orders, 1 underground aquifer, 4 areas with lakes, 2 zones with glaciers, 27 polygenetic and monogenetic volcanoes, and several thermal springs. This discussion explores the implications of various methodologies used to establish the value of the general geodiversity index while also examining the relationships between abiotic elements and their distribution patterns. This forms a fundamental basis for understanding the geosystem services of the basin in terms of regulation, support, and provisioning processes, as well as the culture and knowledge derived from geodiversity. These conceptual elements are indispensable for enhancing the sustainability of a region that is susceptible to the impacts of climate change. Furthermore, they serve as the foundations for the objective’s achievement, as set by the UNESCO Global Geopark project “Volcán del Ruiz”, currently ongoing within the region.

“…However, the variability of the cone (e.g., asymmetry) is not reflected. To explore this, the method of sectorization has been introduced ( [38] and this paper). Sectorization is easiest to understand for circular symmetric cones.…”

DTM-Based Morphometric Analysis of Scoria Cones of the Chaîne des Puys (France)—The Classic and a New Approach

Scoria cones are favorite targets of morphometric research. However, in-depth, DTM-based studies have appeared only recently, and new methods are being developed. This study provides a classic evaluation of the cones of Chaîne des Puys (Auvergne, France) as well as introduces a more detailed and statistics-based set of properties. Beside the classic parameters, a sectorial approach is applied to the slope distributions calculated from high resolution DTMs for 25 cones of different lithologies, in order to study the various (a)symmetries of the cones. DTM-based morphometric characteristics have been found to be different from classic descriptors, whereas the sectorial approach describes correctly the more and the less regular shapes. The distribution of interquartile ranges of the sectorial slope distributions is skewed. Sectorization discriminates various types of symmetries: there are almost circular cones, but the majority are elongated and have some asymmetry. The relationship between size parameters reflects the lithology, rather than the age of the cone. The attempt to relate morphometric parameters to age data is only partially successful: although there is a certain trend, within the same lithological group, subtle but possibly systematic trends can be detected for decreasing morphometric values (e.g., slope) with the age. The regression models indicate various outcomes. Further work is needed to understand all the diverse parameters, especially the lithology–shape relationship, and how symmetry is connected to different factors.
