Resumen
In the course of the Araucaria Project we have collected a huge amount of accurate near-infrared, optical and spectroscopic data for several major distance indicators in some 30 nearby galaxies. The main goal of our project is to improve the three weakest steps in the calibration of primary stellar distance indicators (Cepheids, RR Lyrae stars, TRGB, red clump stars and blue supergiants): the zero point, environmental dependences and proper treatment of the internal extinction. We resume obtained results and discuss the future plans.
