Importance of Topographic Features and Tactical Annotations on Maps Used by Army Aviators for Nap-of-the-Earth Flight.

摘要

This report describes a survey conducted to assist in the definition of requirements for the display of topographic and tactical information for Army aviators. The introductory section of the report describes Army Aviation tasks, difficulties with map use in the performance of these tasks, and the solution of these difficulties through the development of a computer-generated topographic display system. The general objective of the reported project was to support the development of such a computer-based system through identification of the most important topographic and tactical features used in meeting Army aviation mission requirements. One hundred and seven Army aviators participated in the project, completing an extensive survey by rating the importance and frequency of use of specific features. The report presents a series of tables summarizing the results of the project including average importance ratings of each feature, and rankings of features by importance ratings. A discussion of the overall pattern of results is also provided. (Author)
