A method of surveying movements of a terrain. The method may include the steps of providing the raw variations of the coordinates of a plurality of survey points situated on the terrain, and the raw variations of the coordinates of at least one reference point situated on the terrain; determining the real variations of the coordinates of said at least one reference point; and/or calculating corrected variations of the coordinates of the survey points. The method is performed on the basis of the raw variations of the coordinates of the survey points, of the raw variations of the coordinates of said reference point, and of the real variations of the coordinates of said reference point.
