A map is presented of the galactic plane region centered at 16 h 07 m 30 s of right ascension (1950) and -51 deg 35 arcmin 24 arcsec of declination (1950), in the radio continuum at the frequency of 22 GHz with 4.7 arcmin resolution. This map was obtained with the 13.7 m radome enclosed Itapetinga radiotelescope. The physical parameters of the sources detected in the map are presented. In general, the radio emission associated with the sources is of thermal origin and it is optically thin at 22 GHz. One of the most important features found in this work was the detection of the compact optically thick source G 330.9-02, not observed at lower frequencies.
