Estimating information levels-using interpretation to convert data into useable information

Abstract

The amount of information available from several published soil map units is estimated using the Shannon information theory. The amount of information is based on the use of interpretation classes and the Shannon information statistic. Generally the amount of information about intrinsic soil properties such as particle size, shrinkage potential and sodicity is higher than for properties such as pH which are influenced by land management. The implications for the assessment and operation of soil mapping are discussed. Show more
