Since the early days of humanity, people have created maps. At the beginning very simple, and later more and more complex. A map is a simplified depiction of a space which highlights relations between components (objects, regions) of that space. Most usually a map is a two-dimensional, geometrically accurate representation of a three-dimensional space; e.g., a geographical map. More generally, maps can be devised to represent any local property of the world or part of it, or any other space, such as the brain. Map-making dates back to the Stone Age and appears to predate written language by several millennia. One of the oldest surviving maps is painted on a wall of the Catal Huyuk settlement in south-central Anatolia (now Turkey); it dates from about 6200 BC. One who makes maps professionally or privately is called a cartographer.
MapSignal Network mapping or Internet mapping is the study of the physical connectivity of the Internet users trough the map. Network mapping determines the servers and the operating systems run on them of internet-connected networks. It is not to be confused with the remote discovery of which characteristics a computer may possess (operating system, open ports, listening network services, etc), an activity which is called Map Messaging. Map Messaging may be done in a Friend-to-friend network, in which each node connects to the friends on the friends list. This allows for communication with friends of friends and for the building of chatrooms on particular location on map for instant messages with all friends on that network as private or by Gender (SingleG), Personal community (MilkyMate) or international Community (MilkyMap).
Fire Insurance Maps During the late nineteenth and early twentieth centuries, fire insurance maps were periodically drawn up for cities and towns in the United States. These maps were commissioned by insurance companies in order to more accurately calculate fire risk, depicting the layout of the town and showing each existing building. The maps offer a great deal of information, and can show the outline of the building, the building material, the number of stories, doors, windows and chimneys, the address and lot lines, street widths, water pipes, hydrants and cisterns. The Sanborn Company was the largest, but not the only, fire insurance mapping firm. The Sanborn Company was founded in 1867, and created fire insurance maps from 1867 until 1969.
Electronic maps, From the last quarter of the 20th century, the indispensable tool of the cartographer has been the computer. Much of cartography, especially at the data-gathering survey level, has been subsumed by Geographic Information Systems (GIS). The functionality of maps has been greatly advanced by technology simplifying the superimposition of spatially located variables onto existing geographical maps. Interactive, computerised maps are commercially available, allowing users to zoom in or zoom out (respectively meaning to increase or decrease the scale), sometimes by replacing one map with another of different scale, centred where possible on the same point. Mobility satellite navigation systems are computerised maps with route-planning and advice facilities which monitor the users position with the help of satellites.
Cartographers use a system called projection to depict the three-dimensional data of the surface of the Earth to a two-dimensional presentation. The Mercator Projection is the most popular projection for the map of the world. In the aeronautical realm, they use conical projections. With the galloping strides in the information technology, cartography has attained greater sophistication. Geographic Information System (GIS) has made it more scientific, accurate and adaptive to fluctuations in various fronts. Labeling is the system of specifying geographic features like cities, lakes, rivers, etc. in a map. For cartographers, labeling is difficult with the increase in density. Maps are created for the world, the continents, the countries, the provinces or states, smaller units like districts, cities, towns, etc.
Maps of places give details as to the geographic location, physical characteristics, climate profile, vegetative structure, flora and fauna, soil structure, latitude and longitude, etc. Over the years, these maps were used in schools and colleges, offices and in houses for the purpose of education and/or reference. These maps used to be in paper-printed two-dimensional formats. Now three-dimensional, interactive or dynamic maps represent more accurate and up-to-date information. The art and science of map-making is called cartography. Maps are created representing political, geographical and other particular aspects. Most of the maps are drawn on a scale, say 1: 10,000, meaning that one unit of measurement on the map represents 10,000 units on the land. Maps depicting land areas are called political maps or physical maps. Political maps show land boundaries or territorial boarders between states and provinces, say those between India and China or Maharashtra and Gujarat. Physical maps depict geographical features such as terrain structure, mountains, deserts, plateaus, rivers, land under use, etc.
