Photographic plates are well established as stable detectors, well suited for positional astronomy. The completion of the current second epoch 48 inch Schmidt surveys in both hemispheres will provide material spanning baselines of 20–45 years, allowing proper motions to be determined to an accuracy of 4–7 mas yr−1. This paper discusses some of the Galactic structure problems that these data, combined with accurate photometry, can be used to address.
