Remarks about the use of soil names in pedotransfer rules
Original soil names
The soil name has a great importance in defining pedotransfer rules from the SGDBE because it summarises a great amount of information on soil properties that are not directly available from the database. So it is important to know which classification system has been used by the national expert to make the correlation with the national classification system (see paragraph 2.5). Using another soil name instead of the 'original one' when applying PTR can introduce new errors because this soil name is generally an estimation derived from the 'original soil name' and not directly from the national soil name. Thus, when the use of soil names is needed in a pedotransfer rule, it is proposed to use the soil name that was originally given by the national expert and not another one. This can be done using the 'confidence level' attribute attached to each soil name attribute.
