The imagery generated are of historical interest and expected to support current scientific research on climate change and related fields of inquiry. Almost all of the imagery from this camera was declassified in 2012 as a continuation of Executive Order 12951, the same order that declassified CORONA.

The KH-9 program was designed to support mapping requirement and exact positioning of geographical points for the military. The KH-9 panoramic cameras captured high resolution (2-4 feet) images and the terrain camera captured high resolution (2-4 feet) images and the terrain camera captured moderate resolution (20-30 feet) images. High resolution images were acquired on 6.5 inch wide variable length film. The moderate resolution terrain camera acquired images that were printed to 9 inch wide variable length film. The digital products are produced from a duplicate positive film source. The use of browse imagery provides an opportunity to determine if the area of interest is covered and to check for cloud cover.
