Landforms are usually shown on maps by means of contour lines, spot heights, layer tints and/or hillshadings or a combination of these representation methods. This application shows the steps for the production of a layer-tinted map, portraying the volcanic range of SE Luzon Island, the Philippines. The layer-tints (coloured height zones) show the major elevation structures. The map is combined with a hill shading, to show the detailed land forms. All the maps, including two 3-dimensional perspective views, are derived from a digital elevation model.
