Maps are abstract objects used to represent real places and things by use of symbolization. In order for one to create a successful map, the creator must take into consideration the audience. They must ask themselves, who will use this map and what will they use it for? Then, taking into account the needs of the percipient, the creator is able to make a well designed map accordingly.




Map
For other uses, see Map (disambiguation).

A map is a simplified depiction of a space, a navigational aid which highlights relations between objects within that space. Most usually a map is a two-dimensional, geometrically accurate representation of a three-dimensional space.



In 1979, NASA published ATLAS OF MARS: THE 1:5,000,000 MAP SERIES, edited by R.M. Batson, P.M. Bridges, and J.L. Inge, of the U.S. Geological Survey in Flagstaff, Arizona. This was a compendium of airbrushed shaded relief maps, controlled photomosaics, and in a few cases albedo (shading) maps, mostly assembled from Mariner 9 survey images, with some gaps filled by Viking orbiter images. The planet was divided into thirty "quadrangles" or areas, each with an "Mars Chart" or "MC" number (MC-1 through MC-30). The equatorial region was portrayed in the Mercator projection, with Lambert Conformal Conic for the mid-latitudes and Polar Stereographic for the poles. The image above is a reproduction of the new MGS MOC Mars Digital Map.

Conventionally, on most geometrically accurate maps text is upright when the map is oriented with the north up, hence north is identified with the top of a sheet.




-------------------------

Many but not all maps are drawn to a scale, allowing the reader to infer the actual sizes of, and distances between, depicted objects

Making a meaningful map is the ultimate goal.
