A newly updated doctrinal publication (pdf) from the Joint Chiefs of Staff describes the various types of geospatial intelligence products produced by U.S. intelligence agencies and their role in the conduct of joint military operations.
Geospatial intelligence (GEOINT) includes imagery, maps and other data that characterize a target or area of intelligence interest.
The new publication “covers the foundation and evolution of GEOINT; discusses GEOINT support to operations; provides a complete discussion of the roles and responsibilities for GEOINT; discusses GEOINT in terms of the intelligence process;” and more.
