Modeling soil surface roughness by Boolean random functions

In this paper the modeling of soil surface roughness by Boolean random functions is presented. The interest of this class of functions is to be able to model explicitly the cloddy aspect of the soil through the use of primary functions. From a statistical point of view, the height distribution function for such models is easily got, so that classical estimation and modeling methods are available. The case of parametric and non-parametric estimation of the intensity function, and the case of the modeling of the non-stationarity induced by tilling;Ire presented.
