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.
Though a globe model of the earth is the most common version of the earths surface, it would often create a lot of confusions to combine the political and physical maps together. Thats why maps are created for different purposes, which use map projection to depict the earths surface on a plane using a wide variety of scales. Digital maps also use map projections to present data on a computer screen. Different maps use different map projections based on what purpose the map will serve and the scale thats suitable for the purpose. For example, a type of map projection may show severe distortions while mapping the whole country, but may serve as an excellent choice for a countys detailed map that aims to cover a large area. The type of map projections also influences some of the design elements of a map. While some are suitable for small regions, some other projections are good for mapping areas with a huge north-south or east-west extent, or to cover all countries of the world.

Very popular antique maps are fetching very high prices at the auction block, because of this many forgeries have appeared as well as numerous copies of these maps. Map reproductions are not worth anything regardless of what the seller tells you. We will give you a few tips to distinguish a fake antique map from a real antique map. First let us talk about copies, forgeries and reproductions of antique maps. Cartographers have copied each others maps for centuries and have improved on them as well. These old maps can be valuable since they were done when the information on them was valid and useful. They are genuine historical documents. However, recent copies of old maps that depict geographical information from centuries past are made with the intent of offering decoration and sometimes historical insight to their buyers. The value of these map reproductions is often marketed to unknowing customers by claiming that the copy is of a rare map or that is was made using some fancy printing technique. The truth is that a copy of a rare map is not rare, it is the original map that is rare. The copy is worthless and the same goes for the fancy printing.

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.
