Cover Story: Geodiversity denotes variability in abiotic components in a hierarchical natural environment. Arguably, geodiversity underpins biodiversity. As such, geodiversity is essential to geoheritage, geoconservation, and human well-being. While the value of geodiversity is established, the methods of assessing it are not. Geodiversity assessment mainly involves expert judgement. The reliance on expert judgement rather than on direct quantitative valuation introduces ambiguity into geodiversity assessment. Might, however, the aggregate judgement of many experts be better than the judgement of a few? This paper tries to answer the question by crowdsourcing expert judgements and computing geodiversity with spatial multicriteria techniques. The reliability of geodiversity values is conveyed by uncertainty of assessment, which is computed and mapped. View this paper
