High-Quality Imagery

Historical imagery taken from the air is a valuable resource for assessing environmental impacts on the landscape. This non-rectified imagery can be used to compare changes from one year to another. It can also aid in identifying land use coverage, access roads, or bedrock and rock outcrops, making it a very valuable asset for geologists, foresters, and landowners.  

Sewall’s long history of aerial photography dates back to 1948, when the first roll of film was taken for Bangor Hydro.  Much of the early photography was taken in black and white. As time went on, color and color infrared became more and more popular. 

Sewall’s imagery archive is based on a variety of camera sensor types, from film to more recent digital acquisition. Imagery is available in different flying heights. Most photographs were taken in spring leaf-off conditions, fall color, and/or fall leaf-off, although our archive does contain full foliage imagery that was typically used for photo interpretation of forest types.  

Sewall has photo coverage across the state of Maine at different resolutions and seasons. We have full coverage of the State of Maine during at least one flight from 1948 to current.  Sewall also has partial coverage for the following states: Alabama, Connecticut, Florida, Georgia, Illinois, Indiana, Kentucky, Louisiana, Massachusetts, Maryland, Maine, Michigan, Missouri, Mississippi, Montana, North Carolina, New Hampshire, New Jersey, New York, Ohio, Oklahoma, Pennsylvania, Rhode Island, South Carolina, Tennessee, Texas, Virginia, Vermont, and West Virginia, as well as the Canadian Provinces of New Brunswick, Nova Scotia, and Quebec.
