The Z1 can also be predicted to the same locations by simple kriging system of equations, and then added to the m to obtain Z*. dom_i.query(this).after("

Ecological site descriptions (ESDs) and associated state-and-transition models (STMs) provide a nationally consistent classification and information system for defining ecological land units for management applications in the United States. Soil mapping provides important information about the characteristics and condition of the land. dom_i.query(this).after("

Conventional soil mapping now incorporates point observations in the field that are geo-referenced with GPS and digital elevation models visualized in a GIS. dom_i.query(this).addClass('img_'+count);
Digital soil maps illustrate the spatial distribution of soil classes or properties and can document the uncertainty of the soil prediction. The MSAVI is a SAVI that seeks to address some of the limitations of NDVI when applied to areas with a high degree of exposed soil surface (Baratia, Rayegania, Saati, Sharific, & Nasri, 2011). imgMarginRight = imgMarginRight.replace("px","");
Digital soil mapping can be used to create initial soil survey maps, refine or update existing soil surveys, generate specific soil interpretations, and assess risk (Carré et al., 2007). If k = 1, we have linear drift; k = 2 yields quadratic drift; but where there is no trend but deterministic relationships are with some known or readily available and inexpensive covariates (scorpan factors) or other easy-to-measure soil variables, co-kriging has played a major role in efficiently predicting the target soil variable. Scorpan is a mnemonic for an empirical quantitative descriptions of relationships between soil and environmental factors with a view to using these as soil spatial prediction functions for the purpose of Digital soil mapping.

Non-digital soil maps produced as result of manual delineation of soil mapping units may also be digitized or surveyors may draw boundaries using field computers, hence both traditional, knowledge-based and technology and data-driven soil mapping frameworks are in essence digital. The second level consists of interpretations.
Digital soil mapping is the generation of geographically referenced soil databases based on quantitative relationships between spatially explicit environmental data and measurements made in the field and laboratory (McBratney et al., 2003). A pH varying from 5 to 8 was measured in topsoil and subsoil, respectively, in both grassland and forest soils. dom_i.query(this).css("float","none");
Additional studies lead by the USGS have applied DSM tools and products to assess oil and gas well-pad reclamation status and Colorado River salinity management. The use of geospatial techniques for mapping soils is broadly covered by the term “digital soil mapping” (DSM). The use of DSM methods is increasing over time and will eventually cease to be considered distinct, novel techniques.

However, several problems have been identified in the spatial correlation between folk and scientific classification related to different cultural variables that influence local soil classification.
