Minnesota Department of Transportation District 7 Air Photo Collection, 1957-2006

The Minnesota Department of Transportation District 7 Air Photo Collection, 1957-2006 is a series of digitized air photos organized within aerial survey projects commissioned by the Minnesota Department of Transportation (MnDOT). These air photos were used for planning road, bridge, and truck station construction, along with assessing flood areas and wetlands in 13 rural counties of south-central Minnesota. These large-scale air photos provide detailed images of structures and landscapes along rural and urban corridors.

In 2021, this collection of over 27,000 air photos began being digitized and it is an ongoing project. To explore individual digitized air photos, use this Digital Map Library GIS Tool .

In general, air photos are taken from an airplane traveling north-south or east-west. These air photos were flown to provide coverage for highways and rivers, which are not always traditional north-south or east-west flight lines. When using these air photos, please orient the photo as needed.
