If the map is divided into small uniform squares, we may estimate the elevation of the highest point in each square, or use simply the spot heights shown on the map, providing that these, in general, mark elevated points. A curve may then be constructed showing altitudinal distribution of such points over the region. 1948Jrnl. Inst. Navig.
