A multi-sensor, multidisciplinary aerogeophysical survey of a major portion of Afghanistan was recently conducted
by investigators from the Naval Research Laboratory and the U.S. Geological Survey. More than 110,000 line km
of data tracks were flown aboard an NP-3D Orion aircraft. Sensor systems installed on the P-3 included dual
gravimeters, scalar and vector magnetometers, a digital photogrammetric camera, a hyperspectral imager, and
an L-band polarimetric synthetic aperture radar (SAR). Data from all sources were precisely co-registered to the
ground by a combination of interferometric-mode Global Positioning System (GPS) and inertial measurements.
The data from this integrated mapping mission support numerous basic and applied science efforts in
Afghanistan including: resource assessment and exploration for oil, gas, and minerals, development of
techniques for sensor fusion and automated analysis, and topics in crustal geophysics and geodesy. The data
will also support civil infrastructure needs such as cadastral surveying, urban planning and development, and
pipeline/powerline/road routing and construction, agriculture and hydrologic resource management, earthquake
hazard analysis, and base-maps for humanitarian relief missions.
