Aerial Photograph Collection
The MGS Aerial Photograph Collection currently comprises ~ 23,800 photographs, photographic enlargements, and photo-mosaic index maps spanning the 1930s – 1990s. The collection includes the follow ten components:
- County-based, black-and-white aerial photographs (MD; 1930s-1990s)
- Black-and-white photographic enlargements of Fenwick and Assateague Islands (MD; 1950s-1960s)
- Black-and-white photographic enlargements of the Rockville-Laurel area of Montgomery County (MD; 1960s-1970s)
- Black-and-white aerial photograph index maps (MD; 1930s, 1950s-1980s)
- Quadrangle-based, black-and-white aerial photographs (MD; 1930s-1990s)
- High-altitude, black-and-white aerial photographs (MD, PA, VA, WV; 1970s-1980s)
- High altitude, infrared aerial photographs (MD, VA; 1970s)
- Quadrangle-based, infrared aerial photographs (MD; 1980s)
- Black-and-white, Washington, DC and vicinity aerial photographs (Washington, DC, MD, VA; 1930s-1950s)
- Black-and-white, USGS National Water Information System (NWIS) well-related aerial photographs (MD; 1980s)
Component #1 is by far the largest component of this collection, comprising almost ~16,000 aerial photographs. Component #4 contains photo-mosaic index maps (by county) that correlate to the individual photographs in Components #1 and #2. As such, it is relatively easy to search the index maps for an area of interest, and determine which individual photographs from Components #1 or #2 cover that particular area.
SCANNING STATUS & ONLINE AVAILABILITY OF SCANS
MGS’s ultimate objective is to make the digital scans of the aerial photographs available online and to the public. This is a daunting task, due to the sheer number of photographs and the server infrastructure needed to do so.
Thankfully, several of MGS’s Data Preservation Advisory Panel (DPAP) partners – Maryland State Archives (MSA) and the Johns Hopkins University (JHU) Eisenhower Library – have not only helped scan collection components, but have posted many of these series online for public access via their websites.
Here is a list of the items that are currently available online via JHU’s JScholarship or MSA’s Guide to Government Records websites:

AERIAL PHOTOGRAPH COLLECTION INQUIRIES
To request digital scans of our county-based aerial photographs, please first view the Aerial Photograph Index Maps to determine the flight/frame numbers in your area of interest. Digital scans of all of the index maps are available via MSA’s Guide to Government Records website here: http://guide.mdsa.net/pages/history.aspx?ID=SH247. Click on “View all series for MARYLAND GEOLOGICAL SURVEY” at the top of the page and scroll down to find the desired county.
Then, contact any of the MGS staff listed below to request digital scans of the individual frames. Typically, MGS shares digital files via the cloud-based Google Drive platform. Note that the Aerial Photograph Collection does not contain all of the individual frames that comprise the index maps; as such, we may not be able to fulfill your entire request.
To view the paper photographs in person, please schedule a visit to the MGS Library by contacting Mr. Dale Shelton (contact information below). The MGS Library is open weekdays from noon – 430pm. Note that a portion of the county-based photographs are being transferred to an MSA facility in Windsor Mill, MD for permanent storage. MGS can advise patrons regarding the location of their photographs in question.
MGS’s scanning efforts have been funded by successive grants awarded in 2011-2017 by the U.S. Geological Survey (USGS) National Geological and Geophysical Data Preservation Program (NGGDPP). Please visit our “Data Preservation Efforts” webpage for more information about the NGGDPP grants and the ongoing preservation efforts at MGS: Maryland Geological Survey – Data Preservation Efforts
MGS wishes to thank the NGGDPP, as well as members of our Data Preservation Advisory Panel, for fostering data preservation efforts at the Survey. MGS is extremely grateful to MSA and JHU for their assistance in scanning multiple maps, aerial photographs, and publications and making many of these items available online via their websites.
