The Texas Deep Sky Survey (TDSS) is a deep, 5-color photometric and spectroscopic survey of a large area towards the North Galactic Pole, which is being carried out at McDonald Observatory. The goals of this survey are to derive the galaxy luminosity function simultaneously in 5 bands, locate galaxy clusters and map large-scale structure inside a wide contiguous volume, identify QSOs up to very high redshifts, and determine the stellar content and structure of the Galactic halo. The photometric survey currently consists of a 20 sq.\ deg.\ area which is covered in at least the B and RC bands, and a central 2.12 \times 2.12 sq.\ deg.\ area which is complete in the U, B, V, RC, {\rm and} IC passbands, and for which about 730 spectra have so far been obtained. Approximately 50000 objects have been detected in the the central 4.5 sq.\ deg.\ imaging area, to a 5 \sigma limiting magnitude of RC=22.0. Here we describe the 5-band photometric data in the TDSS central region, and present initial object classification based upon colors and morphology.
