From the earliest civilizations maps have been used to portray information about the earth`s surface. A map is a graphical representation of a portion of the earth`s surface, drawn on a plane to some definite scale. Maps are classified as large- scale, small-scale and intermediate-scale maps. A map consists of a group of discrete points, lines and areas that are positioned with reference to a common coordinate system. It is usually represented in two dimensions so that it is easily portrayed on a flat sheet (piece) of paper. The group of lines, points and areas are coded using symbols, textures and colours that are explained in the map legend. The map legend links the non-spiritual attributes to the spiritual data. Symbols, colours, line width and other map elements are selected to suit the need for visual analyses of the map data. A map of the earth or a portion of the earth generally shows the physical features of the country: roads, river, mountains and lakes, land cover types, political boundaries, the situation of towns and cities relatively to each other and by means of the lines of latitude and longitude relatively to every point on the earth`s surface. Maps of the world or large areas are often either 'political' or 'physical'. The most important purpose of the political map is to show territorial borders; the purpose of the physical is to show features of geography such as mountains, soil type or land use. Geological maps show not only the physical surface, but characteristics of the underlying rock, fault lines, and subsurface structures. Maps that depict the surface of the Earth also use a projection, a way of translating the three-dimensional real surface of the geoid to a two-dimensional 21 picture. Perhaps the best-known world-map projection is the Mercator Projection, originally designed as a form of nautical chart. Airplane pilots use aeronautical charts based on a Lambert conformal conic projection, in which a cone is laid over the section of the earth to be mapped. The cone intersects the sphere (the earth) at one or two parallels which are chosen as standard lines. This allows the pilots to plot a great-circle route approximation on a flat, two-dimensional chart.
