Recent progress in VLBI techniques makes it possible to explore the parsec-scale structures in complete wide-field samples of tens of thousands of faint radio sources. In combination with state-of-the-art optical surveys such as the Sloan Digital Sky Survey (SDSS) it permits a census of the small-scale radio structures of faint active and starburst galaxies. Based on our pilot projects we estimate that a sample containing of the order of 104 faint radio sources in the luminosity range 1023 - 1026 W/Hz can now be surveyed at cm wavelengths at the milliarcsecond resolution. Such the high resolution radio survey in conjunction with optical photometric and spectroscopic data from the SDSS will provide a new ground for extragalactic studies.
