What does the orientation photo mean?

"Azimuth photos" usually refer to photos with clear geographical information in photography, that is, photos with shooting direction and latitude and longitude. It is one of the most important data sources in GIS.

There are many ways to get azimuth photos, such as using Global Positioning System (GPS) or Inertial Measurement Unit (IMU) to record the shooting position and direction. In the process of shooting, these devices can record accurate data such as latitude, longitude, elevation and direction, and associate them with the photos taken to form photos with geographical information.

These azimuth photos are widely used in urban planning, natural resource management, disaster assessment and other fields. For example, by analyzing azimuth photos, decision makers can quickly understand the disaster situation in the disaster area and provide an important basis for rescue and reconstruction work. In addition, directional photos can also be used to make 3D maps, street views and so on.
