The Department of Defense (DoD) is offering a postdoctoral fellowship for its Visiting Scientist Program at the National Geospatial-Intelligence Agency (NGA), a world leader in timely, relevant, accurate and actionable GEOINT.
What will I be doing?
With the omnipresence of high quality images available via the internet and social media, high resolution photographs from US -denied corners of the world are available like never before. Oftentimes, these images contain objects of very high interest and intelligence value. But, unlike highly calibrated space-borne and aerial cameras whose image metadata contains sensor position, orientation, calibration characteristics, etc., photographs harvested from personal devices and the internet are absent such metadata – metadata required for accurate photogrammetric exploitation of objects displayed within the image scene.
Even though images harvested from non-metric (unknown) sources typically display very high resolution quality, the process of obtaining accurate dimensions of objects depicted in those images is oftentimes immensely difficult and frequently unfruitful. This is partly attributed to the absence of sensor/lens data, sensor orientation and geolocation, and image cropping (non-full frame images). Additional constraints are presented by the absence of multiple images containing the object(s) of interest, i.e. only a single image being available, and finding object(s) of known size within an image scene, i.e. identifying a known scalar. Lastly, close range images often display perspective foreshortening, and sometimes wide-angle lens distortion, adding additional challenges to photogrammetric exploitation of objects in a scene.
As the selected candidate, you will utilize advances in computer vision and machine learning combined with well-established photogrammetric techniques to derive a camera sensor model from a single or very small-batch of metadata-absent images acquired using consumer grade cameras/mobile devices. The research will involve developing an automated or semi-automated process utilizing learned/recognized common objects, shapes, geometries, and architectural standards present in most photographic scenes. The derived sensor model will enable accurate dimensional analysis of metadata-absent images.
Where will I be located?
You will conduct research remotely under the direction of a mentor who will be based in Springfield, Virginia.
What is the anticipated start date?
NGA is ready to make appointments immediately. Exact start dates will be determined at the time of selection and in coordination with the selected candidate. Applications are reviewed on an ongoing basis and fellowships will be filled as qualified candidates are identified.
What is the appointment length?
Appointments are initially for one year with the option to extend the appointment for up to four additional years, contingent upon project needs and funding availability.
What are the benefits?
As a participant with NGA, you will receive:
The National Geospatial-Intelligence Agency (NGA) delivers world-class geospatial intelligence that provides a decisive advantage to policymakers, warfighters, intelligence professionals, and first responders. Anyone who sails a U.S. ship, flies a U.S. aircraft, makes national policy decisions, fights wars, locates, target, responds to natural disasters, or even navigates with a cellphone relies on NGA. NGA enables all of these critical actions and shapes decisions that impact our world through the indispensable discipline of geospatial intelligence.

This program, administered by Oak Ridge Associated Universities (ORAU) through its contract with the U.S. Department of Energy (DOE) to manage the Oak Ridge Institute for Science and Education (ORISE), was established through an interagency agreement between DOE and DoD. Participants do not enter into an employee/employer relationship with ORISE, ORAU, DoD or any other office or agency. Instead, you will be affiliated with ORISE for the administration of the appointment through the ORISE appointment letter and Terms of Appointment. Proof of health insurance is required for participation in this program. Health insurance can be obtained through ORISE. For more information, visit the ORISE Research Participation Program at the U.S. Department of Defense website: https://orise.orau.gov/dodprograms/.
The qualified candidate will have a doctoral degree or be within nine months of completion of that degree. Degree must have been received within five years of the appointment start date. U.S. military veterans who have been honorably discharged (or who have been medically discharged because of a service-connected disability) and who received a doctoral degree within ten years of the desired start date are also eligible.
Highly competitive applicants will have:
