Abstract: A survey system including a movable photographing device, a surveying device, and an analysis device. The movable photographing device includes a camera mounted on a UAV and taking a plurality of images P for photogrammetry, and a GPS unit including a first time stamping portion stamping a first time Tc relating to a photographing time on the image P taken. The surveying device determines a position of the movable photographing device, and includes a second time stamping portion stamping a second time Tt relating to a surveying time on a survey result R determined above. The analysis device includes a photographing position analysis portion associating each survey result R with a photographing position of the respective image P based on the first time Tc and the second time Tt, and generating data for photogrammetry.
