Cím:Accuracy assessment of different soil databases concerning WRB reference soil groups / Balla Dániel, Varga Orsolya Gyöngyi, Zichar Marianna

Megjegyzések:As a result of international cooperation, the conditions of data access and data usage have been significantlyimproved during the last two decades. Also, the establishment of web-based geoinformaticinfrastructure allowed researchers to share their results with the scientific community more efficientlyon the international level. The aim of this study is to investigate the accuracy of databases with differentspatial resolutions, using the reference profiles of LUCAS topsoil database. In our study, we investigatedthe accuracy of World Reference Base for Soil Resources (WRB) Reference Soil Groups (RSG) groupsstored in freely accessible soil databases (European Soil Database (ESDB), International Soil Referenceand Information Centre (ISRIC)) in Hungary. The study concluded that the continental scale databasetends to be more accurate. We used the Kappa Index of Agreement (KIA) statistical index to evaluate accuracy.The European and the international databases showed a value of 0.9643 and 0.3968, respectively.Considering the results, we can conclude that the spatial resolution has a relevant impact on the accuracyof databases, however, the study should be extended to the national level and the indices should be assessedtogether.
