North Galactic plane structure with IPHAS Be stars
  Our goal is to investigate the spiral structure of the Northern Galactic
plane using as tracers the classical Be stars detected by INT Photometric
H$\alpha$ Survey (IPHAS). IPHAS scans the $29^o<l<+215^o, -5^o<b<+5^o$ region
in the $r$, $i$ and H$\alpha$ bands. Spectroscopic follow up has been done for
the bright H$\alpha$ 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.
