A survey system includes a camera provided on a UAV and taking a plurality of images for photogrammetry. A surveying portion tracking the camera and continuously determining a position of the camera and a relative photographing position calculation portion calculates a relative photographing position of each image based on the plurality of images taken by the camera, and a traveling path calculation portion calculates a traveling path of the UAV from a survey result obtained by the surveying portion. A photogrammetry analysis portion associating a point group of the relative photographing positions calculated by the relative photographing position calculation portion with a flight path calculated by the flight path calculation portion, and generating data for photogrammetry.
