Frame Index File (FIF) Background

• Database of RSDs imagery collected from 1943 to
  Present
• Contains over 475,000 records (from
  approximately 650,000
• total photographs)
• Currently used in several in-house programs,
  including as
• a source for researching orders for
  photographic products

FIF Cleanup will support the proposed Aerial
Photo Ordering System

• Will allow NOAA to make its data holdings
  available more accurately and reliably
• Will help to automate the research, discovery,
  and ordering process of remotely sensed imagery
• Will assist in reducing the number of errors
  that occur in the ordering process
