In the United States, geospatial intelligence is intelligence about the human activity on earth derived from the exploitation and analysis of imagery and geospatial information that describes and visually depicts physical features and geographically referenced activities on the Earth. GEOINT, as defined in US Code, consists of imagery intelligence and geospatial information. GEOINT knowledge and related tradecraft is no longer confined to the U. S. government, or 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. GEOINT encompasses all aspects of imagery and geospatial information and services, it includes, but is not limited to, data ranging from the ultraviolet through the microwave portions of the electromagnetic spectrum, as well as information derived from the analysis of literal imagery.
These types of data can be collected on stationary and moving targets by electro-optical, SAR, related sensor programs and non-technical means. Here Geospatial Intelligence, or the used term GEOINT, is an intelligence discipline comprising the exploitation and analysis of geospatial data and information to describe and visually depict physical features and geographically referenced activities on the Earth. Geospatial Intelligence data sources include imagery and mapping data, whether collected by commercial satellite, government satellite, aircraft, or by other means, such as maps and commercial databases, census information, GPS waypoints, utility schematics, or any discrete data that have locations on earth. There is growing recognition that human geography, socio-cultural intelligence, other aspects of the human domain are a critical domain of GEOINT data due to the now pervasive geo-referencing of demographic and political stability data. There is an emerging recognition that "this legal definition paints with a broad brushstroke an idea of the width and depth of GEOINT" and “GEOINT must evolve further to integrate forms of intelligence and information beyond the traditional sources of geospatial information and imagery, must move from an emphasis on data and analysis to an emphasis on knowledge.”
Key terms, such as GEOINT and NGA, were developed for public policy purposes. The NIMA Act of 1996 establishing the National Imagery and Mapping Agency; this resulted in the integration of multiple sources of information and trade crafts into NIMA, which subsequently became NGA. Director James Clapper designated this discipline as GEOINT, in the ilk of IMINT, SIGINT, MASINT, HUMINT; the question as to how GEOINT is different from other geospatial analytic activities is asked. Bacastow suggested the following First Principles as markers that define the professional domain in terms of uniqueness and value; these are: GEOINT, rooted in the geospatial sciences, geospatial technologies and a tradecraft that seeks knowledge to achieve a decision advantage. Achieving a decision advantage may result in or require information denial and deception. Analysis occurs as a human-machine team. GEOINT reveals how human action is constrained by the physical landscape and human perceptions of Earth. GEOINT seeks to anticipate patterns of life through time.
The data and technical systems reflect human biases. The definitions and usage of the terms geospatial data, geospatial information, geospatial knowledge are not consistent or unambiguous, further exacerbating the situation. Geospatial data can be applied to the output of a collector or collection system before it is processed, i.e. data, sensed. Geospatial Information is geospatial data, processed or had value added to it by a human or machine process. Geospatial knowledge is a structuring of geospatial information, accompanied by an interpretation or analysis; the terms Data, Information and Wisdom are difficult to define, but cannot be used interchangeably. Geospatial intelligence can be more defined as, data and knowledge gathered about entities that can be referenced to a particular location on, above, or below the earth's surface; the intelligence gathering method can include imagery, signals and signatures, human sources, i.e. IMINT, SIGINT, MASINT, HUMINT, as long as a geo-location can be associated with the intelligence.
Thus, rather than being a peer to the other "INTs", geospatial intelligence might better be viewed as the unifying structure of the earth's natural and constructed features —whether as individual layers in a GIS or as composited into a map or chart, imagery representations of the earth, AND, the presentation of the existence of data, and
Office of Naval Intelligence
The Office of Naval Intelligence is the military intelligence agency of the United States Navy. Established in 1882 to advance the Navy's modernization efforts, ONI is the oldest member of the United States Intelligence Community and serves as the nation's premier source of maritime intelligence. Since the First World War, its mission has broadened to include real-time reporting on the developments and activities of foreign navies. S. Navy and its partners. ONI employs over 3,000 military and civilian personnel worldwide and is headquartered at the National Maritime Intelligence Center in Suitland, Maryland. Despite playing an active and decisive role in the American Civil War, in the following years the U. S. Navy fell into precipitous decline. A lack of both federal funding and public interest reduced the Navy's size and technological superiority. S. Navy was wood-based. Towards the end of the 19th century, American naval power had become vastly obsolete compared to Europe, lagged behind the navies of less developed nations such as Ottoman Turkey and Chile.
In an era of rapid industrialization, globalized commerce, colonial expansion, the prevailing military theory of the time held that navies were critical to the commercial and strategic interests of a nation, as well as a source of national prestige and power projection. In light of these developments, American naval officers and military strategists advocated for a larger and more technologically advanced navy that could protect the U. S.' Vast maritime borders, safeguard its commercial interests, project power abroad. Among the leading reformers was Navy Lieutenant Theodorus Bailey Myers Mason, who called for the creation of a naval intelligence office dedicated to gathering information on foreign navies and the latest in naval science to help rebuild the U. S. Navy. William H. Hunt, who served as Secretary of the Navy under President James Garfield, formed a Naval Advisory Board tasked with rebuilding the Navy and bringing it up to par to global standards. In response to Mason's recommendations, on March 23, 1882, Hunt issued General Order No.
292, which read: An "Office of Intelligence" is hereby established in the Bureau of Navigation for the purpose of collecting and recording such naval information as may be useful to the Department in time of war, as well as in peace. To facilitate this work, the Department Library will be combined with the "Office of Intelligence," and placed under the direction of the Chief of the Bureau of Navigation. Commanding and all other officers are directed to avail themselves of all opportunities which may arise to collect and to forward to the "Office of Intelligence" professional matters to serve the object in view; the new Office of Naval Intelligence would be headquartered in the State and Navy Building, with Mason appointed as its first "Chief Intelligence Office". As conceived, ONI assisted in the Navy's advancement by dispatching naval attachés around the world to acquire data and resources related to the latest in naval warfare; these findings would be analyzed and disseminated to Navy leaders and government officials, helping to inform policies and programs related to naval development.
Mason was succeeded as Chief Intelligence Officer by Rear Admiral Raymond P. Rodgers in April 1885. In addition to intensifying ONI's research and surveillance of naval technology abroad, Rodger's four-year tenure saw ONI partner with the U. S. Department of State in gathering information on strategic maritime interests such as Panama and the Kingdom of Hawaii. ONI began to develop capabilities in cryptography, which would foreshadow its evolution into a full-fledged military intelligence office. In 1890, one year after Rodger's departure from ONI, the office was transferred from the Bureau of Navigation to the Secretary of the Navy, solidifying its key role in the Navy's growth and development. ONI's emergence as a proper naval intelligence arm began in earnest with the Spanish–American War of 1898. Naval operations were critical in the conflict, ONI was responsible for protecting Navy Personnel, providing tactical support, implementing counter-intelligence measures. Weaknesses in its intelligence gathering were revealed.
ONI grew in prominence under President Theodore Roosevelt, a former Assistant Secretary of the Navy and naval enthusiast. His expansionist foreign policy — and the central role the U. S. Navy played therein — made maritime intelligence more crucial; the sailing of the "Great White Fleet" around the world between 1906 and 1907, which included sixteen newly constructed steel battleships, showcased new-found American seapower and validated ONI's efforts. By 1911, the U. S. was constructing super-dreadnoughts at a pace that would become competitive with Britain. American entry into the First World War in 1917 marked a turning point in the office's history. President Woodrow Wilson was an exponent of the importance of a strong navy to U. S. defense. Under his administration, Congress authorized ONI's first major increase in personnel and funding, expanded its role to include domestic security operations — namely the protection of U. S. ports and maritime facilities from enemy infiltration and sabotage.
ONI's mandate entailed partnering with the departments of State, Justice and Labor. Due to the sensitive nature of its work, ONI began to censor radio and mail communications, which further marked its
John C. McQueen
John Crawford McQueen was a decorated officer of the United States Marine Corps with the rank of Lieutenant General, who served as high staff officer during Pacific War. He served as Director of Marine Corps Reserve or Commanding General of the Marine Corps Recruit Depot San Diego. John C.
