摘要：ADS40 is an airborne digital sensor with 3 panchromatic and 4 multispectral (RGB and near infrared) CCD line sensors developed and supplied by the LH Systems, LLC. Each panchromatic sensor is set to collect forward, nadir and backward views, and it is able to acquire the same ground area 3 times at different angles. The exterior orientation parameters are calculated from the direct geocoordinate system that uses GPS, inertial measurement unit (IMU) and photogrammetric bundle adjustment. We conducted a study to estimate the mapping accuracy b y utilizing the panchromatic images of ADS40 for the Tsukuba City in Ibaraki Prefecture, Japan. The control and check points, distributed throughout the stud y area, were used to evaluate the accuracy
