We report the study of ISOGAL fields in the outer galactic bulge. We have combined 7 and 15 μ m ISOCAM observations with DENIS IJK s near-infrared data to determine the nature of the sources and the interstellar extinction. Most of the ISOGAL sources show evolution of mass-loss rates in the range 10 -8 to 10 -6 M ⊙ /year. Most of the detected sources are red giants above the RGB tip; a few of them show an excess in and J - K s -[15] colors. These sources are detected as AGB stars with large mass-loss rates.

The Inner Region of the Galaxy has been enigmatic. Some interesting results are becoming available now from the highly promising near and mid infrared surveys such as DENIS, 2MASS, ISOGAL, of this region. The DENIS and ISOGAL surveys have already produced several interesting results over the past couple of years. We have made complementary observations towards the M 16 starforming region to provide additional data at an intermediate wavelength ( H band) compared to the DENIS survey. The data will be used in combination with the other 5 bands from the ISOGAL/DENIS survey to characterise the stellar populations in this region.
