Resumen:
A field of 0.5deg x 0.5deg, at l ~ 265deg and b ~ -2deg, is used as a test bed for stellar structure identification. Spectroscopic and photometric observations were used to estimate distances to the early - type stars inside in the field. Positions, distances and proper motions were combined in a series of statistical analysis to identify clustering. In this way, we are able to characterize stellar structures up to distances of  approximately 8 kpc, probable as far as the outer spiral arm.
