2008 Joint Annual Meeting (5-9 Oct. 2008): Transnational Soil Data Harmonization Database Development.

This paper summarizes the results of the work of a joint Hungarian-Slovakian team to harmonize the data of the two countries and create a WRB based database covering a transnational area. The project has collected recent and archived soil profile data, soil monitoring sites and large scale soil maps of different origin. These data sources were translated to a set of common variables using direct calculations/transformations or pedotransfer rules where direct tranlation were not possible. The harmonized soil profile dataset were than employed to extrapolate the soil variables using geostatistics and remote sensing/digital terrain modeling tools. The extrapolated soil properti layers were used as input factors into the pedotransfer rules to derive WRB reference groups and characteristic diagnostics.
