The Iowa Historic Digital Aerial Photo Project makes 70 years of aerial photos available online.

The Iowa Historic Digital Aerial Photo Project has added a trove of historical imagery thanks to a grant from  the Iowa Department of Natural Resources’ Resource Enhancement and Protection program.

A prior grant funded a project that ran from 2009 through 2011 to source photographs from various state and national archives. Archives in Washington, D.C., the University of Iowa Map Library, the Iowa Department of Transportation, the U.S. Department of Agriculture’s Aerial Photography Field Office, county offices and private national archives were all tapped at that time. Little imagery is available from the 1940s because of World War II.

The remarkable archive provides the means to track change over time, highlighting urbanization and alterations in agricultural landscapes during a 70-year span. Thanks to digital scanning and modern mosaicking techniques, the imagery can be combined with geographic information system data. The site can be accessed at http://programs.iowadnr.gov/maps/aerials/
