Woodlands, for instance, are shown in a green tint; waterways, in blue. Buildings may be shown on the map as black squares or outlines. Recent changes in an area may be shown by a purple overprint. A road may be printed in red or black solid or dashed lines, depending on its size and surface. A list of symbols is available

transparency over the satellite image and outlining the boundaries of areas that appear different. (Tracing paper can be substituted for transparencies.) Students should classify the different land cover types. Areas with the same appearance and characteristics should be classified as the same land cover type and coded with same color or symbol. See Figure 5. Land cover can include urban areas, forests, agricultural lands, and water. Using the topographic map as a reference, add other features that relate to the land
