We have cross-correlated 2MASS and DENIS point sources in 17 galactic fields in order to find systematic astrometric or photometric shifts between the surveys. No significant differences have been found between the data of the two filters in common (J and Ks). This allows to combine data from the two surveys for a further analysis of galactic structure via star counts.
