Victorine [email protected] [email protected] Symbols for digital maps and GIS Symbology is important in maps, as maps are inherently the symbolic representation, in scale, of the real world or a planet.Introduction: Interpreting the colored lines, areas, and other symbols is the first step in using topographic maps. Features are shown as points, lines, or areas, depending on their size and extent. For example, individual houses may be shown as small black squares. For larger buildings, the actual shapes are mapped.

patterns. Also, we use special geologic symbols to indicate 3-dimensionality on our maps. Therefore, a geologic map is nothing more than the representation of 3-d structures on an arbitrary 2-d horizontal plane. Put another way, a geologic map is a cross-section of dipping and plunging structures projected on a horizontal plane.
