A STATE-SPACE MODEL APPROACH TO OPTIMUM SPATIAL SAMPLING DESIGN BASEDON ENTROPY

We consider the spatial sampling design problem for a random field X. This random field is in general assumed not to be directly observable, but sample information from a related variable Y is available. Our pu rpose in this paper is to present a state-space model approach to netw ork design based on Shannon's definition of entropy, and describe its main points with regard to some of the most common practical problems in spatial sampling design. For applications, an adaptation of Ko et a l.'s (1995) algorithm for maximum entropy sampling in this context is provided. We illustrate the methodology using piezometric data from th e Velez aquifer (Malaga, Spain).
