                                           A number of methods have been used to show the relief features of
                                       the Earth’s surface on maps, over the years.    These methods include
                                       hachure, hill shading, layer tints, benchmarks and spot heights and
                                       contours. However, contours and spot heights are predominantly used
                                       to depict the relief of an area on all topographical maps.
