Those who are involved (or merely interested) in the field of geospatial intelligence will want to know about a new Army doctrinal publication on the subject.
“Geospatial intelligence is the exploitation and analysis of imagery and geospatial information to describe, assess, and visually depict physical features and geographically referenced activities on the earth. Geospatial intelligence consists of imagery, imagery intelligence, and geospatial information.”
The new publication provides a comprehensive introduction to the theory and practice of the field. See Geospatial Engineering, ATP 3-34.80, June 2014 (very large pdf).
