A Fully Integrated Solution for Aerial Surveys
2005
<p><i>The focus of this paper is to present the current technological development in the field of system integration for data acquisition and georeferencing for aerial survey applications. The presentation is solely based on a commercial fully integrated system, the Digital Sensor System (DSS). The DSS is a fully-integrated, fully digital ruggedized system for airborne image acquisition, georeferencing, and map production. The DSS consists of a 4K × 4K digital camera, a GPSaided INS direct georeferencing system, and a flight management system. The DSS software suite interfaces seamlessly with commercial off-the-shelf photogrammetric software allowing for fast topographic and orthophoto map production. The DSS currently uses a CCD chip with a 9 µm pixel size which allows digital image acquisition with a ground sample distance that ranges from 0.05 m to 1.0 m using its 35 mm and 55 mm lenses. The embedded POS AV direct georeferencing system provides the exterior orientation parameters in both real-time and post-mission modes. The DSS is used primarily to generate high-resolution color and color infrared digital orthophotos, orthomosaics, and topographic maps which can be used for many different mapping, GIS, and remote sensing applications.</i></p>
