The GEM (Galactic Emission Mapping) project is an international collaboration established with the aim of surveying the full sky at long wavelengths with a multi-frequency radio telescope. A total of 745 hours of observation at 408 MHz were completed from an Equatorial site in Colombia. The observations cover the celestial band $0^h < \alpha < 24^h$, and $-24^{ \circ} \ 22^{ \prime} < \delta < +35^{ \circ} \ 37^{ \prime}$. Preliminary results of this partial survey will be discussed. A review of the instrumental setup and a $\sim 10^{ \circ}$ resolution sky map at 408 MHz is presented.
