Measurements of higher order photon correlations are becoming increasingly attractive due to numerous applications in the field of imaging [1,2]. Recently we demonstrated a detection scheme, which resolves regular 1D source geometries of N independent classical emitters with thermal statistics at sub-Abbe resolution by making use of spatial photon correlations of order m=N [2]. Here we present a generalization of this scheme relying on a sequential measurement of spatial photon correlations of different orders to reconstruct 2D source geometries. By choosing specific detector positions the scheme isolates - depending on the correlation order m - sequentially all spatial frequencies of the setup, which we call spatial frequency filtering. Using the gathered information allows to retrieve the 2D source geometry. In the experiment the independent thermal sources are realized by pinholes drilled in an opaque mask and illuminated with laser light scattered from a rotating ground glass disk.
