MacConnell, William Preston, 1918-

In the 1950s, William P. MacConnell (Class of 1943), and his photogrammetry students in the Dept. of Forestry began using aerial photography to map forests, agricultural fields, wetlands, and other land cover in Massachusetts. Their work was eventually expanded to include the mapping of all land use for Massachusetts, making this state the first in the nation to be completely mapped in this fashion, and laying the foundation for the U.S. Fish and Wildlife Service’s National Wetlands Inventory.

The MacConnell Collection includes a comprehensive set of stereopair photographs derived from multiple transects of the state taken between 1950 and 2000. In addition to some original field notes, a stereoscope, and other project materials, the collection includes the following series:

• 1951: Massachusetts, black and white prints (1:20,000 scale)
• 1971: Massachusetts, black and white prints (1:20,000)
• 1985: Massachusetts and Rhode Island, infrared transparencies (1:25,000)
• 1990: Boston, Cape Cod, Buzzard’s Bay, infrared transparencies (1:12,000)
• 1991-1992: Massachusetts, infrared transparencies (1:40,000)
• 1991-1992: Merrimack River Valley, North Shore, MDC-1, infrared transparencies (1:12,000)
• 1993: Massachusetts, Cape Cod, MDC-2, Nantucket, Dukes and Plymouth Counties, Naushon, West Metro, infrared transparencies (1:12,000)
• 1999: Massachusetts. infrared transparencies and prints (1:25,000)

We are in the process of digitizing the aerial photographs — the 1951-1952 photographs are currently available online. Use the searchable map index to find all available digital images.
