- Abstract
The U.S. Geological Survey’s (USGS) historical remote sensing archive at the Earth Resources Observation and Science (EROS) Center is a comprehensive and impartial record of the Earth’s changing land surface. Images of the same land area acquired year after year provide scientists, disaster managers, engineers, educators, and the general public with a valuable resource. USGS/EROS is responsible for over 8.6 million frames of aerial photographs and 27.7 million satellite images that cover a majority of the Earth’s surface. USGS/EROS has been archiving, managing, and preserving land remote sensing data for over 35 years. The historical archive continues to grow as aircraft and satellites acquire more imagery. Other agencies also call on the USGS to consider their collections for long-term archive support. As a world leader in preserving land remote sensing imagery, USGS/EROS has a reputation as a technological innovator in its efforts to preserve and update the data to ensure that access to these collections is perpetuated in the future. The existing archive, access, and distribution systems face the challenge of meeting rising demands and expectations. In response to these challenges, USGS/EROS strives to advance its expertise in managing and maintaining archive storage facilities and information systems. The task of managing and preserving the historical archive includes information management and technology upgrades in reading, recording, copying, and storing data. To improve access to all the USGS/EROS film archive, each frame on every roll of film is being digitized by automated high performance digital camera systems. These systems robotically capture digital images for the creation of browse and medium resolution image files. Single frame metadata records are also created for this collection to improve access that otherwise involves interpreting flight indexes. This presentation will highlight the transition to providing digital access including browse and delivery of the USGS aerial film archive acquired from 1939 to the present. The collection includes over 61,000 rolls of film (8.6 million frames) that have been archived at EROS since 1973. Access to this archive is available through Earth Explorer (http://earthexplorer.usgs.gov).
