The next ASPRS‐Potomac Region Tech Tour will be held on Wednesday, October 28, 2009, at 2:00 PM, at the National Archives at College Park, Maryland. We will visit the Cartographic, Architectural and Aerial Photographic Records Section, which maintains and provides access to 180,000 to 190,000 cans of film, 20 million images from the 1930’s – 1970’s and 1.2 million maps – a rich source of information that can be used for researchers performing change detection. The tour will provide information for members wishing to use the Archives’ store of maps and aerial photography for their work. The availability and handling of the original negative films is strictly regulated in order to preserve their rich historical value – members will be provided an orientation to this process. The tour is estimated to take approximately an hour, depending upon questions and needs of the group. If you plan to perform research in conjunction with the tour, bring along your area of interest Lat/Long and bounding box coordinates. Requests for film canisters in cold storage normally take 3 days and require a return visit to the Archives for review.  Be sure to bring a photo ID and give plenty of time to travel, park and enter the Archives building.

About the Archives

The National Archives and Records Administration (NARA) safeguards records on which the people of a democracy depend for the continuity, accountability, and credibility of their national institutions. NARA is the official repository of the permanently valuable records made or accumulated by the U.S. Government and is responsible for preserving those records and making them available to the general public, government officials, and scholars. NARA enables people to inspect for themselves the record of what government has done. It enables officials and agencies to review their actions and helps citizens hold them accountable. NARA ensures continuing access to essential evidence that documents the rights of American citizens, the actions of Federal officials, and the national experience.

Among the records in the Cartographic and Architectural Section (NWCSC) are over 15 million maps, charts, aerial photographs, architectural drawings, patents, and ships plans, constituting one of the world's largest accumulations of such documents. These holdings are arranged in 190 record groups, which reflect the origins of the records in specific federal departments and agencies. On-site researchers may examine these records and finding aids in the Cartographic and Architectural Research Room.

Maps that predate the Federal Government and 19th century maps of areas outside the United States are rare among the unit's holdings.
