Digital Soil Mapping techniques to Prediction of soil attributes (properties and classes) in digital soil mapping (DSM) is based on the correlation between primary soil attributes and secondary environmental attributes. Digital soil mapping makes extensive use of secondary information, such as that contained in remote sensing images and digital elevation models. However, it cannot do without taking samples of the soil itself. Therefore, methods and guidelines need to be developed that assist users in designing spatial sample configurations for use in digital soil mapping. Existing geostatistical methods are insufficient because these typically have been developed for situations in which there is no secondary information. In this paper, we explore how the existing methods may be extended to the case in which the secondary information is spatially exhaustive and where soil mapping is done using as the creation, and population of spatial soil information systems (SSINFOS), universal kriging and SCORPAN Method. It is timely to develop and implement methodologies. More....
