Photometric Identification of Objects from Galaxy Evolution Explorer
  Survey and Sloan Digital Sky Survey
  We have used GALEX and SDSS observations to extract 7 band photometric
magnitudes for over 80,000 objects in the vicinity of the North Galactic Pole.
Although these had been identified as stars by the SDSS pipeline, we found
through fitting with model SEDs that most were, in fact, of extragalactic
origin. Only about 9% of these objects turned out to be main sequence stars and
about 11% were white dwarfs and red giants collectively, while galaxies and
quasars contributed to the remaining 80% of the data. We have classified these
objects into different spectral types (for the stars) and into different
galactic types (for the galaxies). As part of our fitting procedure, we derive
the distance and extinction to each object and the photometric redshift towards
galaxies and quasars. This method easily allows for the addition of any number
of observations to cover a more diverse range of wavelengths, as well as the
addition of any number of model templates. The primary objective of this work
is to eventually derive a 3-dimensional extinction map of the Milky Way galaxy.
