Measuring higher-order photon correlations is an emerging technique in the field of imaging to overcome the classical resolution limit [1-4]. We propose to use higher-order spatial photon cross-correlations measured in the far field of statistically independent thermal light sources (TLS) to reconstruct arbitrary two-dimensional TLS source geometries. The technique generalizes an earlier imaging scheme which resolves one-dimensional source arrangements with sub-Abbe resolution [4]. By choosing specific detector positions the technique allows to sequentially isolate the spatial frequencies of the sample within different correlation orders, enabling us to retrieve the source distribution with increased accuracy. We present experimental data verifying the theoretical predictions and discuss the conditions under which sub-Abbe resolution is achieved. [1] Oppel et al., Phys. Rev. Lett. 109 233603 (2012); [2] T.
