A survey system for accurately surveying an area includes a coordinate acquisition section that acquires a set of three-dimensional coordinates of a survey point or a base station used for determining sets of coordinates of the area, as a set of measurement coordinates, a comparative coordinate acquisition section that acquires at least a height-direction coordinate value of a set of comparative coordinates indicating a position within a predetermined range from the acquired set of measurement coordinates; and a determining section that calculates a difference between a height-direction coordinate value of the set of measurement coordinates and the height-direction coordinate value of the set of comparative coordinates and determines that at least any one of the set of measurement coordinates and the set of comparative coordinates are incorrect when the difference is larger than a predetermined value.
