Air Photo Coverage – Map Library

Most of the photos in the Map Library were flown by companies under contract to the US Department of Agriculture’s Agricultural Adjustment Administration, Agricultural Stabilization and Conservation Service or Production and Marketing Administration or through nationwide programs such as the National High Altitude Photography Program (NHAP) and the National Aerial Photography Program (NAPP). Photos of the Chicago Metropolitan Area from 1975 were produced by the Northeastern Illinois Planning Commission (NIPC).

Photos in sets predating 1988 received by the Map Library as gifts from county-based agencies and potentially are incomplete. If a set of photos lacks a substantial portion, it is indicated in the table below.
