Digital orthophotography provides all of the visual content of a photograph while being as accurate as a map for measurements. It is a vital component of the IndianaMap, a framework layer that serves as a basemap.
The Orthophotography Progam aims to update and maintain Indiana's orthophotography on an ongoing basis. The first major initiative began in 2005, and entailed collecting digital data for the entire state. Since then, portion of the state are being updated on a rotating basis.
