| description | As a result of international cooperation, the conditions of data access and data usage have been significantly improved during the last two decades. Also, the establishment of web-based geoinformatic
infrastructure allowed researchers to share their results with the scientific community more efficiently
on the international level. The aim of this study is to investigate the accuracy of databases with different
spatial resolutions, using the reference profiles of LUCAS topsoil database. In our study, we investigated
the accuracy of World Reference Base for Soil Resources (WRB) Reference Soil Groups (RSG) groups
stored in freely accessible soil databases (European Soil Database (ESDB), International Soil Reference
and Information Centre (ISRIC)) in Hungary. The study concluded that the continental scale database
tends 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 accuracy
of databases, however, the study should be extended to the national level and the indices should be assessed together. |
