Abstract : This article proposes a combination of 2.5- and 5-meter intervals. Negative and positive relief forms are distinguished on the map by the use of hachures. The minimum area of negative forms which may be differentiated on a 1:25,000 topographic map is determined to be about 2 sq mm. For positive relief forms this limit may be slightly reduced, since in this case the hachures are directed outwards from the closed contour line. In mapping the relief of sandy deserts to a scale of 1:25,000, relief forms with an area of not less than 2 sq mm may be plotted on the map.
