From geodiversity assessment to geosite analysis – a GIS-aided workflow from the Bakony–Balaton UNESCO Global Geopark, Hungary

Abstract Geodiversity and geosite assessments precede geoheritage and geotourism utilization. The process first determines the geodiversity value of an area (based on geoscientific attributions) and then the geotourism potential of the available sites. As a result, significant geosites can be identified, which are the bases for protection and tourism. During geosite assessment, scientific and infrastructural aspects are essential because spectacular sites and landscapes carrying intrinsic or visible values generate interest among tourists and professionals. In this study, a quantitative workflow to determine the geodiversity index over an area, evaluate geosites and monitor significant ones is presented. The study area is the Bakony–Balaton UNESCO Global Geopark, where no quantitative assessment was conducted previously. A GIS-based geodiversity analysis identified the most diverse areas which gave the basis for the geosite assessment done in a ‘geodiverse’ subregion of the geopark. The most important nine of the 75 identified potential geosites were chosen to examine the spatial variance of the assessment. By continuous monitoring, we got an image of what the visitors liked or did not like there. In this way, we were able to monitor the various opinions of geotourists to present unique development strategies for each of them. A connection between the location of geosites and the spatial distribution of geodiversity values was also determined by analysing and visualizing the connection between geodiversity and geosite assessment results.
