Imagery Intelligence (IMINT) includes representations of objects reproduced electronically or by optical means on film, electronic display devices, or other media. Imagery can be derived from visual photography, radar sensors, infrared sensors, lasers, and electro-optics.
Geospatial Intelligence (GEOINT) is the analysis and visual representation of security related activities on the earth. It is produced through an integration of imagery, imagery intelligence, and geospatial information.

Imagery Intelligence (IMINT) is sometimes also referred to as photo intelligence (PHOTINT). One of the earliest forms of IMINT took place during the Civil War, when soldiers were sent up in balloons to gather intelligence about their surroundings. IMINT was practiced to a greater extent in World Wars I and II when both sides took photographs from airplanes. Today, the National Reconnaissance Office designs, builds, and operates imagery satellites, while the National Geospatial-Intelligence Agency is largely responsible for processing and using the imagery. Geospatial Intelligence (GEOINT) is the analysis and visual representation of security related activities on the earth. It is produced through an integration of imagery, imagery intelligence, and geospatial information.
