AMS Frames Hand Assembled from Original GRE Framelets


Availability: At NSSDC, Ready for Offline Distribution (or Staging if Digital)

Time span: 1967-08-06 to 1967-08-18


This data set is one complete set of third generation 20- by 24-in. film sheets. These sheets were prepared by the Army Map Service (AMS) from a negative copy of the prime GRE record made by Eastman Kodak Co. A positive contact print was prepared, then cut along the fiducial lines to separate individual framelets. These framelets were mounted on a tranparent backing in correct sequence and orientation, and a film negative was made by contact printing. The actual image measures 15.5 by 20 in. Frame identification appears on each print. One MR photo appears on one sheet film, whereas 3 sheet film negatives are required to produce one HR frame. These photographs have lost photometric relationships useful in slope determination because of the density control technique utilized. This technique also caused bright areas to print as a gray tone. However, the control technique does make interpretation of the photographs easier in some circumstances.
