What does an image's geolocation data contain?

• A. Sensor's location
• B. Ground sampling distance
• C. Colour calibration
• D. Sensor's type

Answer: (A)

Geolocation data attached to an image records where the photo was taken. This shows up in the image’s metadata (often EXIF) as the sensor’s location—usually the drone’s GPS coordinates with latitude, longitude, and sometimes altitude and heading. This location information is what lets you place the image on a map or tie it to real-world coordinates for mapping or surveying tasks. Ground sampling distance is about how much ground a single pixel represents, which is a measure of image resolution rather than where the image was captured. Colour calibration concerns color accuracy and consistency, not location. Sensor’s type refers to what kind of sensor was used, which again is about hardware, not where the image was taken. So the geolocation data specifically contains the sensor’s location.
