What is geotagging in relation to photographs?

Geotagging in relation to photographs refers specifically to the process of adding GPS coordinates to images. This technology enables a photograph to include metadata that tells where the picture was taken, which can enhance the value of the photo by providing context related to its geographical location. When a camera or smartphone captures an image, if it has GPS capabilities, it can automatically attach the latitude and longitude of the location where the image was shot. This practice is useful for organizing, sharing, and retrieving photos based on the location, allowing users to search or filter images by their geographical data.

The other options pertain to different aspects of photography or data management but do not define geotagging. Tracking movement relates to analyzing or recording the motion of objects, identifying objects in images focuses on image recognition technology, and recording timestamps of images involves noting down when a photo was taken, which is a separate piece of metadata that does not involve location. Thus, the definition of geotagging is best encapsulated by the addition of GPS coordinates to images.
