We present a morphologic analysis of radiosources extracted from the 5 GHz VSOP Active Galactic Nucleus Survey III, composed by 102 AGN´s in the range 0.01 < z < 3.2. Using public data bases, we generated photometric catalogues of the 102 objects in 6 bands (B, V, R, J, H, K). A selection by near-infrarred color was made (0.7<H-K<0.9) to obtain a sample with similar evolutionary characteristics. This reduce the total sample to 30 objects (0.1 < z < 1.0). Considering existing models, this indicate a correlation between the evolutionary state and redshift of the objects in different wavelength, we expected that radiosources at low and high redshift, have different morphologies. Nevertheless, the obtained results do not show indications of this correlation (for radiosources with z<1), in agreement with other investigations.
