Infrared study of Galactic massive star forming regions.

The study of massive stars in massive star forming regions and their environment is difficult due to their larger distances, deeply embedded in their natal clouds and cluster environment. The identification of the young embedded clusters around massive stars and their associated members are also challenging from background and foreground stars. Infrared observations are very useful to study the massive stars and their immediate environment with good spatial resolution and high sensitivity.
I will present the new results obtained from basic photometric analysis of infrared observations on the massive star forming regions. I will discuss the clustering of young stellar objects (YSOs), the interaction and feedback of massive stars to their immediate environments using infrared images.
