A procedure has been developed to establish whether or not area-wide soil information in the Key Register of the Subsurface (BRO) meets the requirements of the user with regard to accuracy and spatial detail, and to select the most efficient additional mapping method to meet these requirements. A trade-off between costs and accuracy appears to be easier in simple applications than in multiple applications. In the latter case, accuracy is often assumed to be 70% map purity. However, this criterion needs to be more accurately defined and substantiated and, if necessary, adjusted on the basis of the results of risk analyses. Furthermore, it is necessary to monitor where and for which soil characteristics the Soil Map of the Netherlands, scale 1 : 50,000, meets this quality criterion.
