Digital Mapping of Soil Classes and Continuous Soil Properties

摘要: Soil is often described as mantling the land more or less continuously with exception being where there bare rock and ice (Webster Oliver 2006). Our understanding of soil variation in any region usually based on only a small number observations made field. Across spatial domain interest, predictions distribution properties are at unobserved locations observations. There two principal approaches for making locations. The first approach subdivides coverage into discrete units within which soils conform to characteristics class some classification (Heuvelink Webster 2001). second treats suite continuous variables attempts describe way these vary across landscape necessarily quantitative, it requires numerical methods interpolation between actual
