A display system includes: a three-dimensional data storage unit that stores three-dimensional data indicating a three-dimensional shape in a first range of a construction site in which a work machine operates; a detection data acquisition unit that acquires detection data indicating a three-dimensional shape in a second range that is a part of the first range; an update unit that updates a partial range of the three-dimensional data on the basis of the detection data; and a display control unit that causes a display apparatus to display an updated range and a non-updated range in different display forms in the three-dimensional data.
