正射影像图制作

本产品为数据生产服务，利用卫星、无人机等平台搭载影像采集设备，对指定区域，经地面真实影像采集、几何校正、地面控制点的选取和标定、地理配准等工艺，制作形成正射影像数据集。

This product is a data production service. It equips platforms such as satellites and unmanned aerial vehicles (UAVs) with image acquisition devices, and generates an orthophoto dataset for designated regions through processes including ground truth image collection, geometric correction, selection and calibration of ground control points (GCPs), and georeferencing.
