Imagery intelligence in the context of "Aerial photography"

The National Reconnaissance Office (NRO) is a member of the United States Intelligence Community and an agency of the United States Department of Defense which designs, builds, launches, and operates the reconnaissance satellites of the U.S. federal government. It provides satellite intelligence to several government agencies, particularly signals intelligence (SIGINT) to the National Security Agency (NSA), imagery intelligence (IMINT) to the National Geospatial-Intelligence Agency (NGA), and measurement and signature intelligence (MASINT) to the Defense Intelligence Agency (DIA). The NRO announced in 2023 that it plans within the following decade to quadruple the number of satellites it operates and increase the number of signals and images it delivers by a factor of ten.

NRO is considered, along with the Central Intelligence Agency (CIA), NSA, DIA, and NGA, to be one of the "big five" U.S. intelligence agencies. The NRO is headquartered in Chantilly, Virginia, 2 miles (3.2 km) south of Washington Dulles International Airport.

Human intelligence (HUMINT, pronounced /ˈhjuːmɪnt/ HEW-mint) is intelligence-gathering by means of human sources and interpersonal communication. It is distinct from more technical intelligence-gathering disciplines, such as signals intelligence (SIGINT), imagery intelligence (IMINT) and measurement and signature intelligence (MASINT). HUMINT can be conducted in a variety of ways, including via espionage, reconnaissance, interrogation, witness interviews, or torture. Although associated with military and intelligence agencies, HUMINT can also apply in various civilian sectors such as law enforcement.

In the United States, geospatial intelligence (GEOINT) is intelligence about the human activity on Earth derived from the exploitation and analysis of imagery, signals, or signatures with geospatial information. GEOINT describes, assesses, and visually depicts physical features and geographically referenced activities on the Earth. GEOINT, as defined in US Code, consists of imagery, imagery intelligence (IMINT) and geospatial information.

Today, GEOINT knowledge and tradecraft are not confined to the U.S. government, or even the world's leading military powers. Additionally, countries such as India are holding GEOINT-specific conferences. While other countries may define geospatial intelligence somewhat differently than does the U.S., the use of GEOINT data and services is the same.

A reconnaissance aircraft (colloquially, a spy plane) is a military aircraft designed or adapted to perform aerial reconnaissance with roles including collection of imagery intelligence (including using photography), signals intelligence, as well as measurement and signature intelligence. Modern technology has also enabled some aircraft and UAVs to carry out real-time surveillance in addition to general intelligence gathering.

Before the development of devices such as radar, military forces relied on reconnaissance aircraft for visual observation and scouting of enemy movement. An example is the PBY Catalina maritime patrol flying boat used by the Allies in World War II: a flight of U.S. Navy Catalinas spotted part of the Japanese fleet approaching Midway Island, beginning the Battle of Midway.

Aerial reconnaissance is reconnaissance for a military or strategic purpose that is conducted using reconnaissance aircraft. The role of reconnaissance can fulfil a variety of requirements including artillery spotting, the collection of imagery intelligence, and the observation of enemy maneuvers.

The Defence Intelligence Fusion Centre (DIFC) is based at RAF Wyton in Cambridgeshire. Largely created from the staff of the National Imagery Exploitation Centre (formerly known as the Joint Air Reconnaissance Intelligence Centre (JARIC)) and then known for several years as the Defence Geospatial Intelligence Fusion Centre, it can trace its history back to clandestine reconnaissance operations at the beginning of the Second World War by Sidney Cotton on behalf of MI6 and then MI4, and the formation of the Allied Central Interpretation Unit at RAF Medmenham (sister to Bletchley Park).

Today, DIFC's role has grown beyond just imagery intelligence. Part of the Joint Forces Intelligence Group (JFIG) within Defence Intelligence, DIFC's primary role is to support Defence planning, current operations and the intelligence assessment process. DIFC still provides specialist imagery intelligence, but also conducts multi-disciplinary intelligence fusion for the armed forces and other UK Government partners. The integrated multi-disciplinary Task Groups at DIFC use data and reporting from various sources (including satellite imagery), together with other advanced technologies, to provide critical information and over-watch to tactical, operational and strategic decision makers.
