treaty monitoring. They also work on diverse issues such as environmental concerns, counternarcotics, disaster assessments, infrastructure, underground facilities, and counterterrorism.

GEOINT Analyst (Imagery Science)—apply advanced techniques to determine the intelligence and geospatial information contained in imagery. They develop algorithms, evaluate tools, and create customized methodologies and products to address a variety of geospatial intelligence problems. They typically specialize in precision mensuration, radar, spectral, infrared, and other specialized collection systems.

GEOINT Analyst (Infrared Source Analysis)—specialize in metric reconstruction, trajectory analysis, and assessment of activity using nonliteral, infrared data from persistent geospatial intelligence sources to support characterization of foreign weapon system performance, counterproliferation, battlespace awareness, and other intelligence issues. The analysts apply their understanding of weapon systems, spatial and temporal reconstruction, error analysis, signature interpretation, sensor phenomenology, and orbital mechanics to help solve intelligence issues in accordance with the national intelligence priority framework. They communicate the meaning and significance of their analysis as written, visual, and/or oral geospatial intelligence.

GEOINT Analyst (Lidar Image Science)—analyze point cloud data to derive intelligence and geospatial information. They conduct feature extraction, characterize partially obscured objects, and perform change detection to support or extend analysis. They develop algorithms, evaluate tools, and create customized lidar methodologies to address a variety of geospatial intelligence problems.

GEOINT Analyst (Maritime)—acquire, analyze, compile, and disseminate maritime safety information and intelligence to populate and update nautical databases to support the digital nautical chart, hardcopy charts, digital publications, and electronic chart display and information systems. They generate missionspecific data and products, promulgate worldwide navigational warnings, and respond to queries from foreign hydrographic offices and the users of NGA products and services. These duties are performed in fulfillment of the agency’s marine navigation obligations under U.S. Code, Title 10, other federal and international laws and regulations, in support of national security goals, concerns, and strategies.

GEOINT Analyst (Nautical Cartography )—acquire, analyze, evaluate, and compile nautical products and mission-specific data in support of mission requirements and navigation safety. They evaluate information from a variety of sources to include foreign nautical charts, foreign notice to mariners, imagery, bathymetry, publications, ship reports, and other forms of geospatial intelligence against current NGA hydrographic data holdings. They ensure the quality, accuracy, and currency of nautical information produced either in-house or in cooperation with contractors and national and international co-producers for national, military, and civil customers.

GEOINT Analyst (Open Source Research)—discover, retrieve, and analyze open and classified source data and apply expertise in evaluating and acquiring sources of data. They develop regional and subject expertise in order to provide information tailored to mission requirements. They collaborate with other intelligence community agencies and outside institutions to enhance information access and resource sharing. They recommend and acquire source materials to enhance resource center collections and provide training to help customers optimize the use of open source in support of the GEOINT mission.

GEOINT Analyst (Persistent Operations)—specialize in the real-time execution of tasking, collection, processing, exploitation, and dissemination of persistent GEOINT resources and data. Real-time execution incorporates multi-INT collaborative inputs to address long-term and emerging customer requirements. Emphasis is placed on time-dominant assessment and reporting, sensor allocation, and responsive collection capabilities of persistent GEOINT sensors.

GEOINT Analyst (Photogrammetric Image Science)—apply advanced techniques to measure the precise dimensions or relative size of objects on imagery. This includes monoscopic, stereoscopic, overhead,
