of the map, while the size of the ellipse corresponded to the amount of distortion in area. In a nineteenth-century cartographic context, in which professionals looked for ways to apply mathematical principles to the science of mapping and the map projection, Tissot's theory was favorably received, at least in continental Europe. Even in the more restrained Anglo-American academic world, a columnist of Science, a publication sponsored by the American Association for the Advancement of Science, hailed Tissot's method and encouraged his readers to study his work in the hope that such a study "will lead to the adoption of better projections than those which are at present in use." The legacy of Tissot’s method is still vivid today, as suggested by the authors of Map Projections for Europe, who argue that since Tissot’s famous analysis regarding distortion, the only major scientific development in the metric interpretation of deformation has been Eduard Imhof's Verzerrungsgitter, or deformation grid.
