Lattices of coupled maps on the interval are used to test some ideas of Y. Pomeau concerning estimates of the number of degrees of freedom per unit length of a spatially incoherent system. Qualitative agreement is found between dimension densities obtained using two-point measurements at separated lattice points and dimension densities obtained using spatial decay of the correlation function.
