AbstractTo investigate a huge sample of data related to the Stellar Abundance and Galactic Evolution ( SAGE) survey in more detail, we are performing a northern sky photometric survey named SAGES with the SAGE photometric system. This system consists of eight filters: Stromgren-u, SAGE-v, SDSS g, r, i, DDO-51, H alpha(wide) and H alpha(narrow), including three Sloan broadband filters, three intermediate-band filters, two narrow-band filters and one newly-designed narrow-band filter. SAGES covers similar to 12 000 square degrees of the northern sky with delta > -5 degrees, excluding the Galactic disk (vertical bar b vertical bar < 10 degrees) and the sky area 12 h < RA < 18 h. The photometric detection limit depth at signal-to-noise ratio 5 sigma can be as deep as V similar to 20 mag. SAGES will produce a photometric catalog with uniform depth for similar to 500 million stars with atmospheric parameters including effective temperature T-eff, surface gravity log g and metallicity Fe/H
