Welcome to CoreFacts, where we're always short on time and big on science. I'm Steve Sobieszczyk. Let's get right to it, today's question is:

Will Declassified Satellite imagery be digitized?

No, Declassified Satellite imagery will not be digitized. However, they are available as a High Resolution Scanned Product. For background, The USGS Earth Resources Observations and Science Data Center has archived thousands of rolls of film containing several million frames of historical aerial and satellite photographs dating back to the 1930's and these were gathered from various Federal agencies. This archive includes the rather well known, often utilized NHAP and NAPP film, but the largest portion of this archive consists of original film acquired in support of the USGS 1:24,000 topographic quadrangle map series, taken during the 1940s through the 1970s. Most of this photography is reasonably large scale to support the production of the quadrangle maps.

And now you know. Join us again tomorrow as we'll give you yet another new CoreFact.
