Our goal is to investigate the spiral structure of the Northern Galactic plane using as tracers the classical Be stars detected by INT Photometric Hα Survey (IPHAS). IPHAS scans the 29o<l<+215o,−5o<b<+5o region in the r, i and Hα bands. Spectroscopic follow up has been done for the bright Hα emitters. We have developed an automatic procedure for spectral analysis, based on the BCD spectrophotometric system. In this paper we present a cataloque of 1135 Classical Be stars, for which we have determined spectral types, astrophysical parameters and distances. From these results we make a first attempt to map the structure of the Galactic disk in the anticenter direction.
