Recent observations by atmospheric Cherenkov telescopes such as H.E.S.S., and MAGIC have revealed a large number of new sources of very-high-energy (VHE) gamma-rays above 100 GeV mostly concentrated along the Galactic plane. At lower energies (100 MeV - 10 GeV) the satellite-based instrument EGRET revealed a population of sources clustering along the Galactic Plane. Given their adjacent energy bands a systematic investigation of a correlation seems appropriate. While a large number of sources are only detected in one energy band, several sources can be connected, such as (amongst others) the source in the Kookaburra region (HESS J1420-607/3EG J1420-6038). In this paper we describe the common properties of the sources detected in both energy regimes including predictions for the upcoming space-based instrument GLAST-LAT.
