Hennepin County Aerial Imagery

About the data

Hennepin County publishes current and historical aerial imagery that is available to the public through web services. Spring 2015 leaf-off imagery is currently the most recent available. Since 2000, the county has captured digital aerial orthophotography approximately every three years. Based on this schedule, countywide orthoimagery services are available for 2000, 2002, 2004, 2006, 2009, 2012, and 2015. (Lower-resolution 2005 imagery is also available from the USDA MN Farm Service Agency.) A variety of other imagery services are available from years prior to 2000 and have been collected from various sources, including scanning and geo-rectifying physical image archives. Historical imagery varies in resolution and coverage area from year to year, and some years of imagery cover only a portion of the county. Additional years of historical imagery will continue to be added as they are converted to digital format and published.
