In this work we present the first measurement of the spatial distributionof the cosmological parameters performed with an automatic analysis of the latest Cosmic Microwave Background (CMB) data from Planck. In order to treat all the data in an homogeneous way and to reduce the cpu-time involved in the parameters estimation, we developed a machine learning algorithm that was trained with simulated data and tested comparing with the results of the standard montecarlo estimation. Although we found some anisotropies, this are not signifcant and are of the order as the ones found in mock catalogues.
