F IKSEL (1988) provides an asymptotically unbiased kernel estimator for the density h s ( r ) of the spherical contact distribution function of stationary and isotropic point processes. This paper proposes alternative estimators of h s ( r ) for use with regular grid of locations. The existing estimator of h s ( r ) and the alternatives proposed in this paper are then tested out in a simulation study.
