As the primary repository for information on Michigan's historic resources, the SHPO maintains an inventory of over 300,000 cards, 600 reports, maps, 6,000 rolls of negatives, and nearly 20,000 color slides. Since the State Survey Data is accessible to federal, state, regional and local planning officials, it can be referenced when making decisions regarding issues such as zoning, local historic districting, downtown marketing and urban revitalization. As a public resource, the State Survey Data may be consulted on a scheduled appointment basis during regular business hours.
