Applanix provided this month’s cover image, demonstrating the capabilities
of the DSS 322 Digital Sensor System. The orthomosaic of the University of Kentucky Campus in Lexington,
KY, USA was generated at a ground sampling distance of 18cm using Inpho Ortho Box with USGS 1/3” National Elevation Dataset DEM. Navigation data was post processed using Applanix Airborne POSPac
software. The imagery was captured by Photo Science
Inc. on January 12th, 2006, using a 60mm lens.
The DSS Digital Sensor System is a ready-to-use,
directly georeferenced, medium-format, airborne
digital camera system and has proven to be the
digital imaging answer for airborne remote sensing
applications that require a rapid, easy to use and
cost-effective solution. The DSS 322 is comprised
of an integrated POSTrack Flight Management and
Direct Georeferencing System, a medium format
True Color and CIR Digital Imager with Yaw stabilized
Azimuth mount, a ruggedized data logger and
pressurized drive, and a complete suite of post-processing
software for image development and direct
geoerferencing. A mapping-quality alternative to
large-format digital cameras, the DSS is designed to
generate high-quality color and CIR directly georeferenced
digital imagery that produces an accurate
and radiometrically consistent product with 0.05m
to 1m GSD.
A photogrammetric calibration process for consumer-grade
digital cameras is proposed whereby a single image coordinate
correction function is determined for the full zoom/focus
range of the camera.
Automatic registration of airborne images with complex local
distortion is approached by combining area-based methods
with local transformation models.
