The primary aim of this project is to use VLBI observations to measure accurate distances to and proper motions of 6.7 GHz methanol masers in the third and fourth quadrants of the Galaxy. These observations will allow us to improve our knowledge of the structure of the Galaxy and complements a similar study being done in the northern hemisphere looking at 12.2 GHz methanol masers in the first and second quadrants. 6.7 GHz methanol masers are considered to be one of the best tracers of the earliest stages of high-mass star formation and thus these observations can also be used to investigate the processes involved in massive star formation. The high resolution proper motion observations will enable us to determine the environment (expanding gas, linear shocks, accretion disks etc.) in which methanol masers form.
