“…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).…”

“…The second most widely adopted spatial analytical technique was the development of a digital elevation model to calculate a roughness index (Figure S2A). In the years following 2015, new spatial methods were introduced to quantify geodiversity such as map algebra (Perotti et al, 2019), centroid analysis (Nobre da Silva et al, 2019), cell statistics (Pellitero et al, 2015), factor mapping and a virtual globe flight simulator (Martinez-Grana et al, 2015) approach.…”

“…Geoheritage is used to describe the importance (Diaz-Martinez, 2011) or quality (Pellitero et al, 2015) of the site and is the process of determining whether geodiversity has significant scientific, educational, cultural or aesthetic value (Diaz-Martinez, 2011). However, the assessment of geodiversity and its methodological procedures as a whole, independently of the terms and values mentioned above, is considered a separate research domain that has been under significant development in recent years (Brilha, 2015) by many scholars (Nobre da Silva et al, 2019; Ozsahin, 2017; Pellitero et al, 2011, 2015; Serrano et al, 2009). This study reviews quantitative geodiversity assessment literature to highlight key knowledge gaps, current trends and avenues for future research.…”

Geodiversity assessment is recent and is passing through a stage of methodological development and consolidation. With rapid environmental change, improving the developmental states of geodiversity assessment is of paramount importance. A scientometric analysis is presented to identify knowledge gaps, current trends and avenues for future research in quantitative geodiversity assessment literature. The study is categorised into three areas of analysis: (a) methodological intentions of geodiversity assessment, (b) current trends in geodiversity assessment methods and (c) current geographic trends. A ranking tool was developed to determine whether the current methodological intentions of geodiversity assessments trend towards combined geodiversity and biodiversity assessments or towards the independent assessment of geodiversity. Results showed that about 50% of publications independently assessed geodiversity with no consideration for biodiversity, 32% discussed or reviewed geodiversity by mentioning potential links to biodiversity and 12% more strongly linked geodiversity assessment to biodiversity assessment. Tools used by scholars to determine geodiversity values varied from statistical through to the more frequently adopted geographic information systems (GIS) and spatial analytical software approaches. Study sites selected for geodiversity assessments were predominantly terrestrial at the state-wide scale. Marine assessments, or seabed geodiversity, were mostly absent from the literature, with only two publications found. Brazil in South America had many geodiversity assessments and European scholars have played crucial roles in the development of quantitative geodiversity assessment in recent years. Subsequent research will benefit from developing a unified geodiversity assessment approach, reaching a consensus on an accepted definition and standardising the geodiversity concept, broadening research site environment types and developing strategies to promote further international and intranational collaboration.

“…This method was well utilized by de Silva, do Nascimento, and Mansur in their assessment of geodiversity in the Seridó Geopark Project in northeast Brazil. Bétard and Peulvast also used geodiversity and threat indexes to identify geodiversity hotspots in the Ceará State (northeastern Brazil) [9,10]. The geodiversity index can be seen as the sum of geological diversity, gemorphodiversity, pedodiversity and hydrodiversity.…”

The article demonstrates a method for quantitative-qualitative geodiversity assessment based on core elements of abiotic nature (geology and geomorphology) according to a proposed weight multiplied by the area of spread through the studied region. The territory of the Coromandel Peninsula was selected as a case study due to its diverse geology and geomorphology. The north part of the Peninsula (Port Jackson, Fletcher Bay and Port Charles districts) was chosen because of the variety of rock types (sedimentary and volcanic groups) covering the region, while historical stratovolcano remnants and old sediments provide a good variety of meadow hills and weathered coastal cliffs. Meanwhile, the method utilizes easily accessible data (topographical and geological map) to assess slope angle (morphometry) and rock groups, including their age (geology) to identify areas in the sample region with significant geodiversity values. Moreover, the aim of this research is to make the assessment of geodiversity simpler and more accessible for various parts of the world with minimal required information. In this paper, we provide access to improve and utilize this method in geologically diverse territories to select the best areas for geotourism, geoeducation and geconservation planning.

“…The assessment of geodiversity is carried out through both qualitative [9,[12][13][14][15] and quantitative [10,[16][17][18][19][20][21][22][23][24] assessment methods. These procedures make it possible to propose conservation plans (e.g., geoparks), to identify areas of interest (e.g., geological heritage) and to regulate their sustainable use (e.g., geotourism) [8,25,26].…”

The relevant geomorphological characteristics of territory represent an essential part of its natural heritage. They are also an asset to be exploited for stimulating socio-economic development. The “Ruta Escondida” in Ecuador constitutes a historical place full of culture and landscapes that have been shaped over time by geological and geomorphological processes. Among the geomorphological features of the study area, volcanic cones, hilltops, terraces, foothills and glacial valleys stand out. The aims of this work were: (1) to characterize 18 places of geomorphological interest, located in the northern part of the Ruta Escondida and (2) to propose alternatives (geotourism) to contribute to the local development of the area. The applied methodology included: (1) the compilation of geomorphological elements; (2) the assessment of geomorphosites using the Inventario Español de Lugares de Interés Geológico (IELIG) method and (3) a strengths–opportunities–weaknesses–threats analysis of the contribution and influence of geomorphosites in the development of the study area. With this work, it was possible to determine that all the analyzed geomorphological sites have a high and very high interest. The strengths, weaknesses, opportunities, and threats (SWOT) analysis revealed that the geomorphosites could provide significant added value to the development of geotourism on the route, complementing the already known cultural and historical attractions.
