Document title

Geostatistical mapping of geomorphic variables in the presence of trend

Authors(s) and Affiliation(s)



The AA. summarize the theory of residual maximum likelihood (REML) as it applies to kriging in the presence of trend. They present the equations to show how estimates of the trend are combined with kriging of residuals to give empirical best linear unbiased predictions (E-BLUPs). They then apply the method to estimate the height of the sub-Upper-Chalk surface beneath the Chiltern Hills of southeast England from 238 borehole data. The variogram of the REML residuals is substantially different from that computed bu ordinary least sqares (OSL) analysis. The map of the predicted surface is similar to that made from kriging with the OLS variogram
