Image Scientist

Full Time
D.C. Metro


Level: Expert

Location: Quantico, VA


Position Description:

The candidate shall provide imagery science services within NGA in support of GEOINT analysis and advanced phenomenology. Knowledge of imaging systems, phenomenology, methodologies and processing techniques shall be employed on behalf of GEOINT analysts and community customers while providing operational support. Individual image scientists shall be a specialist in one of five distinct areas depending on mission requirements. Services shall include, but are not limited to:

  • Utilize expert knowledge of imaging systems, phenomenology, and processing techniques
  • Specialty in one of five distinct areas depending on mission requirements. These areas of specialty include:
    • Synthetic Aperture Radar (SAR) –Imaging radar advanced scientific and quantitative analysis techniques utilizing advanced image and signal processing methods.
    • Imaging radar physics, phenomenology, and phase history processing
    • Spectral –Spectral imaging (multispectral and hyperspectral imagery), phenomenology, and processing techniques shall be employed on behalf of image analysts and community customers. This shall include proficiency at performing processes including atmospheric correction, change detection, target detection, scene categorization, extraction of land use land cover analysis, and vegetation analysis. Familiarity with commercial and civil data sources and integration of resulting data into Arc GIS is required
    • Infrared –Infrared scientific and quantitative analysis techniques utilizing advanced image and signal processing methods. Physics, math, radiometry, and thermal analysis are required
    • Photogrammetry –Applying photogrammetric techniques to remotely sensed imagery in panchromatic, color, and stereo modes. Proficiency with mathematics and data adjustment is required. Photogrammetrists perform image assessment, point selection, mensuration, triangulation, orthorectification, and processing in order to produce standard and non-standard image products. They increase the relative and absolute positioning accuracy of imagery from a variety of sensors to support mono and stereo exploitation. These analysts assess, evaluate, and extract elevation data from stereo imagery. They support both internal and external customers and assess products for adherence to standards and accuracy requirements. Use mathematical concepts and techniques to solve complex GEOINT analysis issues and understand concepts associated with structured data and relational databases.
    • LIDAR –Scientifically processing and exploiting LIDAR data, to include viewshed\line of sight analysis, point cloud manipulation and editing, Z-clipping, slope, hillshade, aspect analysis, feature digitization, FOPEN analysis, and 3D modeling. Extensive knowledge of imaging radar physics, phenomenology, and phase history processing.
  • Primary products will include presenting processed images and scientific analysis to GEOINT analysts and managers in support of Analysis production and providing Subject Matter Expert (SME) services in various forums
  • Interaction directly with NGA/A GEOINT analyst customers as support requirements arise, and devise an optimal approach to processing and scientifically analyzing spectral imagery in a timely manner given the available tools and techniques
  • Presentation of processed images and scientific analysis to imagery analysts and managers. Analysts who use advanced imagery data are usually not familiar with it, and the resulting analysis must be presented and explained in a manner the customer can understand. The Subcontractor shall provide results to the customer with the requested form and content, including project related briefings as required
  • Ad-hoc informational briefings and training for the purpose of educating analysts and managers as to the capabilities of imagery data processing and its benefit, to include presentations to the Commonwealth countries
  • Support and participation in community forums on an ad-hoc basis. This will sometimes require presentation of technical information or case studies resulting from operational support, to include presentations to the Commonwealth countries
  • Providing Subject Matter Expert (SME) support to the Community and other NGA components and Contractors. Activities may include attending Technical Exchange Meetings (TEM), user testing and evaluation of new capabilities under development, and advising various NGA directorates (e.g., participation as a user on SCRUM team in AGILE sprints)
  • Investigating new scientific analysis techniques and methods if requirements cannot be met in a timely manner with available tools and methods. This could include monitoring the community and industry for new technologies that can be inserted for operational use, or the near-term formulation of algorithms and applications
  • Provide informal/ad-hoc imagery products, briefings, and short reports as a result of operational image science support projects
  • Formal written reports of selected products may be required which must conform to reporting standards of NGA/A
  • Understanding of deductive reasoning and implementation of the scientific method as it applies to GEOINT analysis is also required
  • Explain assumptions, analytical techniques, and statistical results effectively in writing and orally to convey intelligence problems being resolved


Job Requirements:

  • Advanced formal training in remote sensing and/or earth science/physical science, or engineering/mathematical disciplines
  • Detailed experience using AGI processing and exploitation software
  • Proficiency in the sensor disciplines (radar, infrared, spectral, or geospatial)
  • Detailed knowledge of Basic SAR AGI collection systems (both space-borne and airborne), operations, phenomenology, and their impact on SAR AGI processing analysis, and exploitation
  • Detailed knowledge in the science of infrared image formation, collection parameters, processing, and radiometric analysis
  • Proficiency with using COTS image software (e.g. ENVI, ERDAS Imagine), COTS desktop software (e.g. MS Office), and the Windows and UNIX operating environments. Of particular importance are software packages used for the processing and analysis of imaging radar data.
  • Knowledge of imaging radar system technology and collection parameters.
  • Demonstrated strong writing and briefing skills consistent with national-level performance, this includes the skills needed to prepare NGA Imagery Intelligence Brief reports.
  • A bachelor’s degree in a field related to the support services may count for up to four years of this experience. A master’s degree in a field related to the support services may count for an additional two years of this experience. A doctorate degree in a field related to the support services may count for up to three years of this experience
  • More than 20 years experience required
