Cutting-edge technology used by Cornerstone Mapping for aerial photography

Airborne GPS and
Inertial Measurement Unit

GPS Base Station

Applanix DSS 439
	The DSS 439 is a compact, airborne digital camera system. The turnkey system is complete with airborne GPS, intertial navigtion unit (IMU), flight navigtion and a 39-megapixel sensor. The USGS has certified the DSS as "capable of providing quality, consistent image data to support civil government mapping and orthophotography product development."
	• Geometrically Accurate Imagery • Radiometrically Calibrated • Color Infrared (CIR) & True Color Capabilities • Azimuth Mount for Aircraft Crab Compensation

The latest 39-megapixel sensor is integrated with GPS & IMU.

Direct Georeferencing enables us to provide high-accuracy orthophotos without ground control.

The ability to capture CIR imagery has many practical applications. Since active vegetation reflects near-infrared radiation, imagery can be used to study the location, type, and condition of vegetation.
