Indiana Historical Aerial Photo Index
The Indiana Geological Survey (IGS) has created the "Indiana Historical Aerial Photo Index" (IHAPI) interactive map to facilitate the identification and retrieval of historical aerial photographs. More than 950 large-format photomosaic index maps in the IGS archive were scanned and georeferenced, and then mosaicked to produce 466 county-based images dating from the 1930s to the 1980s.
