Abstract
A coregionalization simulation consists of the generation of realizati ons of a group of spatially related random variables. The Fourier inte gral method is presented, modified to carry out such a multivariable s imulation. This method allows the simulation of realizations with any specified symmetrical covariance matrix and it is not limited to the c lassic linear model of coregionalization. The results of gaussian nonc onditinal simulations from a case study modeling the spatial character istics of a layer of coal are given.
