Consider a spatial point pattern realized from an inhomogeneous Poisson process on a bounded Borel set
, with intensity function λ (s; θ), where
. In this article, we show that the maximum likelihood estimator
and the Bayes estimator
are consistent, asymptotically normal, and asymptotically efficient as the sample region
. These results extend asymptotic results of Kutoyants (1984), proved for an inhomogeneous Poisson process on [0, T]
, where T →∞. They also formalize (and extend to the multiparameter case) results announced by Krickeberg (1982), for the spatial domain
. Furthermore, a Cramér–Rao lower bound is found for any estimator
of θ. The asymptotic properties of
and
are considered for modulated (Cox (1972)), and linear Poisson processes.
