Marschner Air Photo Collection

The Marschner Air Photo Collection is a plate series of aerial photographs ranging from 1935 to 1953. The series includes over 450 photographs of locations throughout the continental United States highlighting specific geographic land patterns, like plains, plateaus, valleys, rivers, basins, and prairies. The collection of aerial photographs was compiled by F.J. (Francis Joseph) Marschner, an agricultural economist and cartographer from the U.S. Department of Agriculture. The photographs served as a reference source for Marschner’s map Major Land Uses in the United States. There is about a 50% overlap of photos from the same location (same Map Reference ID).
