Mapping Human Terrain
What is human terrain? In the 1970's US Military groups such as the Army and Navy sought information on Korea and Vietnam during the Vietnam war. The main focus for finding information on the two waring countries was to, first, know the people living in those countries, and secondly, to know the geography on where to place US troops.
That brings us back to defining what human terrain is. The National Geospatial-Intelligence College (NGC) states that, "[human terrain] augments... traditional approaches with the addition of data and models that describe the behavior, attitudes, perceptions, and relationships of people in the context of their environment." In 1945, the Joint Army-Navy Intelligence Study (JANIS) was created to be a all-in-one report of a geographical region.
JANIS 75 was of Korea and provided high quality and accurate data from each subsection of the country. This gave Military officials a great resource and knowledge-base to determine where to put their troops.
