High Resolution Digital Aerial Imagery and Products
ADS40 Airborne Digital Sensor
The ADS40 Airborne Digital Sensor unites photogrammetric precision for positional accuracy of processed data with multispectral capabilities for image analysis and interpretation. Developed jointly with world experts in high performance digital sensors (DLR - German Aerospace Center), the ADS40 enables users to create geospatial end products smoothly, efficiently and profitably in an end-to-end digital environment.
Benefits • three sensors in one - black and white, color and false color • wide area coverage for big cost savings • perfect RGB co-registration through special trichroid filter • high quality DTMs from three-line stereo sensor data • reduced ground control requirements • end-to-end digital flow - no film processing or scanning • pressure sensitive interface screen • smooth data flow to SOCET SET® or other software • complements LiDAR, even at flying heights above 2000 m • seamless strip imagery along each flight line
The ADS40 Airborne Digital Sensor is capable of producing imagery of sufficient geometric and radiometric quality for the full range of both photogrammetric and remote sensing processing. A high performance system for earth data collection from airborne platforms, the ADS40 uses state-of-the-art technology to offer photogrammetric performance in the same range as the refined aerial film cameras that underlie the success of aerial photography and photogrammetry. The advantages include:
• wide area coverage - easier to work with than multiple images from small format CCD array cameras • captures all spectral bands simultaneously - no film-type restrictions • only one lens system to calibrate • automatic drift setting • performance of gyro-stabilized mount enhanced by input of IMU data to maximize image quality • automatic calculation of CCD integration time (exposure time) • direct linear response of CCD - no variation due to exposure settings and processing conditions • linear CCDs, telecentric lens and interference filters deliver well defined spectral bands - essential for successful multispectral analysis • single focal plate operates at a constant temperature - essential for maintaining operating status and signal-to-noise ratio • well known supplier with decades of expertise in supplying and supporting aerial film cameras
