The dataset provides geographic index grids that link users to scanned aerial photographs covering Arlington County from 1934 through 1989. These indexes help researchers, planners, historians, and GIS staff locate and access historical aerial imagery for specific years and areas within the county. Not all photographic series are complete, and the associated imagery is stored and distributed as PDF files.",
