The main tools typically used to investigate the nature of the extragalactic gamma-ray background (EGB) are its energy spectrum and population studies of resolved point sources.
However, a larger amount of information is contained in the full gamma-ray maps, and this can be exploited to further push the study of the EGB.
This information can be encoded into different observables like the auto-correlation, the pixel statistics and the cross-correlation.
In the talk I will review these complementary observables, the current status, measurements, and the constraints on the EGB derived from them, with
some emphasis on the cross-correlation with galaxy catalogs.
