In 1960, geographic intelligence in the US Armed Forces was decentralized. The Intelligence and Mapping Division of the US Army Corps of Engineers was primarily responsible for creation of military intelligence concerning the surface of the earth excluding the oceans and seas for the armed forces of the United States. Engineer intelligence guides were issued to provide guidance concerning collection, processing, production, and dissemination of geographic intelligence to elements of the Corps of Engineers.

This engineer intelligence guide explains the differences between maps and terrain diagrams and provides examples using actual maps and terrain diagrams. The maps and terrain diagrams used as examples mostly show areas in foreign countries. One particularly striking set of illustrations contrast maps and various types of terrain diagrams of the Mt. Fujiyama area in Japan (pages 10-13).

This guide discusses the preparation of terrain diagrams in details with extensive illustrations, and discusses and illustrates preparation of terrain diagrams for various types of terrain and for various types of special features including offshore features.

This guide contains a one-page “Selected bibliography of physiographic and block diagramming” compiled by Mark W. Pangborn in 1958. The bibliography contains a section on theory and technique and a list of outstanding examples of physiographic diagrams.

The guide also contains an extensive distribution list showing engineering related officials and organizations within the US Army which were concerned with geographic intelligence.
