Detailed maps of 70 OH and H2O masers associated with star-forming regions have been made with the VLA at an angular resolution of ∼2″ arc. The absolute position accuracy is 0″.5 for both the OH and H2O observations, and the relative position accuracy of maser spots within a group is 0″.1 for each species. For about half of the sources compact H II regions are detected at 22 GHz with 0″.1 positional accuracy relative to the strongest H2O maser. Preliminary results are presented, with emphasis on the spatial relationship between the OH and H2O masers and compact H II regions.
