Abstract: The project of the informational system creation on the problem of evolution of radio galaxies is described. This system, being developed at present at the server (, will allow a user to operate with simulated curves of spectral energy distributions (SED) and to estimate ages and redshifts by photometric data using ?2-method. Authors use SEDs of several models (GISSEL'98 (Bruzual, Charlot, 1996), PEGASE (Fioc, Rocca-Volmerange, 1996, 1998) and Poggianti (1996)) for different types of galaxies. Synthetic spectra are smoothed by the filter sensitivity curves before the procedure of age estimation. There is a possibility to calculate extinctions in different filters using infrared maps. The server contains full archive of RC-catalog radio galaxy images obtained with 6-m telescope of SAO and VLA data. Modes of access, formats of output result and additional functions are described.
