2005 Indiana Orthophotography Project
In 2005, the Indiana Geographic Information Council (IGIC) coordinated the 2005 Statewide Digital Orthophotography Program, which facilitated the acquisition of statewide, high-resolution orthophotography and digital elevation data for Indiana.
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. From these images, a point index was created showing the upper-right corners of 113,035 individual historical aerial photographs. The interactive map allows users to easily locate a site of interest and determine unique identification numbers for individual photos. Copies of the photos can then be ordered from various archival collections, including the IGS archive.
