Results of comparison of Gaia DR2 parallaxes with data derived from a
combined analysis of 2MASS (Two Micron All-Sky Survey), SDSS (Sloan Digital Sky
Survey), GALEX (Galaxy Evolution Explorer), and UKIDSS (UKIRT Infrared Deep Sky
Survey) surveys in four selected high-latitude $|b|>48^{circ}$ sky areas are
presented. It is shown that multicolor photometric data from large modern
surveys can be used for parameterization of stars closer than 4400 pc and
brighter than $g_{SDSS} = 19.^m6$, including estimation of parallax and
interstellar extinction value. However, the stellar luminosity class should be
properly determined.
