Using IMU/GPS Data Using Exterior Orientation for Automatic Points Measurement
ADS40 Airborne Digital Sensor ADS40 consists of seven parallel CCD lines in the focal plane of a single lens system – three panchromatic (forward-,nadir-, backward looking), red, green and blue Placed next to each other and near infrared. Each panchromatic channel consists of two lines, each with 12000 pixels, staggered by 0.5 pixel, usually one staggered line for each panchromatic channel is used.
