Book Description
The model, the task analysis results, and a survey of equipment for reference displays were all used to evaluate design alternatives for indexing, storage forms, storage media, and displays, as well as requirements and displays for auxiliary data. Three modes of TIIF operation-manual, semi-automated, and automated-were considered. Reference storage forms, media, and displays should be selected in the context of a manual or automated TIIF system. For a manual system, references should be in their original form and stored in file cabinets. For an automated system, references should be standardized according to interpreter needs and controlled by a computer processing unit. Reference indexes should be designed for each type of reference, utilizing existing indexes as far as possible. Collection and processing of auxiliary information should be automated for ease of subsequent processing. The code matrix block should be used whenever possible. The displays of auxiliary information should relate to whether the system is manual or automated. For the manual system, auxiliary displays should be viewed in hard copy or in the original format. For the automated system, displays, if needed, should be under computer control. Additional information for a code matrix block should include aircraft stabilization data. (Author).

Book Description
An experiment conducted to compare two methods--graphic and textual-- of indexing reference materials for use of image interpreters in a tactical image interpretation facility is reported. The objective was to evaluate the two methods for speed and accuracy in locating rolls of reference imagery in a TIIF. Image interpreters trained in the use of area-oriented graphic and textual indexes to tactical imagery on roll film were required in two experiments to obtain from indexes the accession number of rolls of imagery containing coverage for a given area. Interpreter performance with both types of indexes was compared for accuracy and speed. Major findings were: (1) Interpreters took less time on the average with the textual index when areas were small; (2) with the graphic index, less time was taken when areas were large. The longer time taken with the textual index to locate desired imagery for large areas appeared due to recording and analyses tasks required under these conditions. Conclusions point to the greater utility of the graphic index in a manual image processing system where coverage of large geographical areas is required or if image coverage has to be precisely defined. The textual index appears more useful in a computerized system where coverage of small area targets with less definition is the major requirement.
