Development of predictive mapping techniques for soil survey and salinity mapping

Creator:

Elnaggar, Abdelhamid A.

Abstract:

Conventional soil maps represent a valuable source of information about soil characteristics, however they are subjective, very expensive, and time-consuming to prepare. Also, they do not include explicit information about the conceptual mental model used in developing them nor information about their accuracy, in addition to the error associated with...

Use of decision tree analysis for predictive soils mapping and implementation on the Malheur County, Oregon initial soil survey

Creator:

Hash, Sarah Jane

Abstract:

Soil surveys provide essential information for making land use and management decisions on publicly-owned lands in the semi-arid Great Basin. Soil maps produced with conventional mapping techniques are time-consuming, costly, and do not explicitly document the soil scientist's mental soil-landscape model. Predictive soils mapping using decision tree analysis (DTA) can...
