Years ago, people looking for antique maps would often have to wait around for opportunities to find them. They may have had to wait for their vacation periods in order to find the time to travel to find them at different famous shopping outlets or antique stores. Many collectors have gone to antique stores all over the world looking for the artifacts that they found interesting. Today, finding old maps is easier than ever before due to the availability of online shopping opportunities. There are entire websites devoted to locating old maps and selling the ones that are available. Old world map enthusiasts should spend some time searching for what theyre looking for online, and they should be on their way to getting the sort of ancient maps theyve always wanted.
Conformal projection: These projections maintain angular relationships and show accurate shapes while covering small areas. Such maps are useful for navigational or meteorological purposes where angular relationships are important. Equidistant projection: Maps that maintain accurate distances along given lines or from the center of the projection are based on this principle of equidistant projection. Such maps are used for navigation and for radio and seismic mapping. The Equirectangular projection and the Equidistant Conic projection are two examples of this category. Azimuthal (or zenithal) projection: A projection that maintains accurate angular relationships and directions from a given central point use this projection. Maps for aeronautical purposes use this principle. The Lambert Azimuthal Equal-Area projection and the Gnomonic projection are examples of how azimuthal projection is used for map making.
Map projections are classified based on: Distortion characteristics: Some projections often need to show a particular area or its relative size accurately for distributions or other phenomena. These are called equivalent or an equal area projection. The Lambert Azimuthal projection that maps a sphere to a disk, and accurately shows all regions of the sphere is an example of this category. However, this equal area projection fails to represent angles with accuracy. The Albers projection is another instance of equal area map projection that utilizes two standard parallels. Despite no preservation of scale and shape, the distortion in this case is found to be minimal between the standard parallels.
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.
A Scene of Relativity World wall maps can provide an interesting perspective on the world we live in. Not all world maps are in the standard format we are used to with the Northern Hemisphere in the top the map, with the Americas on the left (West) and China and the Indonesia on the right (East). There are some interesting world maps which are formatted in a different way. The Pacific Centred wall map Europe and the Americas on separate sides of the map. There are also upside down style maps of the world where the southern Hemisphere is now in the north of the map, and countries like Australia, Brazil and South Africa are now in the northerly part of the map. By looking on a world map at the area you live in, you can clearly see what countries and geographical features are around you which give a scene of relativity. Social Talking Point People find maps comforting as it gives them some grounding and something familiar to look at. World maps instantly draw people in to look at them. They notice where they live, where they have travelled and where they are currently. Even if they have seen a world map countless times before, there is sure to be something people see every time they look at a map. People comment on the different styles or designs of maps, colours used or the size and finish of a map.
MapSignal application offers; zooming in entails one or a combination of: Real-time map messaging service (MapSignal) by a more detailed about Human generated signals (SingleG/GPassenger) (available/unavailable icons) enlarging the same map or enlarging the pixels, hence showing more detail by removing less information compared to the less detailed version enlarging the same map with the pixels enlarged (replaced by rectangles of pixels); no additional detail is shown, but, depending on the quality of ones vision, possibly more detail can be seen; if a computer display does not show adjacent pixels really separate, but overlapping instead (this does not apply for an LCD, but may apply for a cathode ray tube & Mobile Applications such as Cell phone, PDA, Smart Phone), then replacing a pixel by a rectangle of pixels does show more detail.
