江苏省防汛抗旱抢险中心倾斜摄影模型数据

利用大疆MTK系列无人机在江苏防汛抗旱抢险中心示范试验坝段开展倾斜摄影建模工作，飞行高度100m，建模范围为以示范试验坝段为中心的周围1平方千米，建模精度为2.5cm,平面坐标系采用WGS84坐标系，高程系统采用1985国家高程基准，基本等高距0.5m。Oblique photogrammetry modeling was conducted using DJI MTK-series unmanned aerial vehicles (UAVs) at the demonstration test dam section of the Jiangsu Flood Control, Drought Relief and Emergency Rescue Center. The flight altitude was set at 100 meters, the modeling scope covered an area of 1 square kilometer centered on the demonstration test dam section, with a modeling accuracy of 2.5 cm. The planar coordinate system adopted the WGS84 coordinate system, the elevation system used the 1985 National Elevation Datum, and the basic contour interval was 0.5 meters.
