We present a deep multicolor NIR survey that we are currently undertaking at the Instituto de Astrofísica de Canarias (Spain). The aim of the survey is obtain deep star counts in selected areas distributed along the Galactic plane to analyze the large scale structure of the Milky Way and the galactic components, in particular the Galactic bar. We are at least one magnitude deeper than in 2MASS and DENIS Galactic surveys, and even more in the inner Galaxy, as we are less limited by source confusion. This provides a better analysis of those regions where the extinction is higher.
