What Is an Aerial Survey?

Aerial survey, now also called photogrammetry and remote sensing. It belongs to the science of remote sensing in the science of surveying and mapping. Remote sensing science and technology is an emerging edge discipline developed on the basis of the infiltration and integration of space science, electronic science, earth science, computer science and other disciplines. To get spatiotemporal information about the target. Not only focusing on solving the geometric positioning of traditional targets, but also more importantly, semantic and non-semantic interpretation of image and non-image information obtained by outer space sensors, and extracting geometric and physical feature information of various target objects in the objective world To provide scientific technology and methods for people to understand and transform nature; to provide scientific basis and decision support for major national and departmental decision-making and sustainable social development; and to provide visual military intelligence services for national defense construction and national security. Because its science, technology, application, and service involve a wide range of scientific and technological fields, its application has penetrated into economic construction, social development, national security, and people's lives.
