A map is a 2D, or in rare cases, 3D representation of a geographical or urban location. It can come in various types, including political maps that detail territories and locations of cities, physical maps, which detail the environmental factors of areas in a similar manner to satellite images, road maps for detailing various routes in a given area, and topographical maps, which detail the elevation of a given area.
During the San Hieronymo Incident in 1970, various maps were also included in some secret documents pertaining to various locations on the Soviet base on the San Hieronymo Peninsula. Big Boss also discovered a map of Costa Rica at the Puerto del Alba facility during the Peace Walker Incident in 1974, although it only printed the various locations on the map, not labelling any routes to access them. Nonetheless, the map did allow Big Boss and Kazuhira Miller to deduce the terrain of El Cenegal when planning how to find the Sandinista comandante.
Behind the scenes
The map was a frequent gameplay element of the various radar systems in the Metal Gear games. In Metal Gear Solid 3: Snake Eater, however, the player has to use the Survival Viewer to access the map. The map in Metal Gear Solid 3 allows the player to locate where the player had placed various traps (such as mouse traps), and was also essential for the boss battle against The End, as it detailed potential sniping positions that The End could utilize.
