Orthophotomatics

Due to the rapidly changing landscape, mainly due to human activity, it is necessary to collect and update spatial data using methods that are highly efficient, powerful and fast. Such methods include aerial measurement imaging and results processed into digital ortho-photo images or ortho-photos.鉴于空间场景正快速演变，且此类变化主要由人类活动驱动，亟需采用高效、高性能且快速的方法来收集并更新空间数据。此类方法包括航空测量成像技术，以及将成像结果处理为数字正射影像（digital ortho-photo images，简称正射影像（ortho-photos））。
