World travel map collectors have long known how nice it is to sit in the comfort of your own home and gaze at the wide world without having to get out of their easy chairs. A world map is a wonderful gift or thing to dream over whether you are a traveler or a dreamer. Everyone has had the experience of first realizing that a map wasnt just a picture or illustration but an actual representation of the wide world. In terms of childhood fantasies, many an explorer, vagabond, or traveler got their start by gazing at the maps which came each month in the National Geographic magazine. For those who are actually on the road, a map can be a priceless item to have in their possession. The best maps offer insights and information about the places that travelers visit such as major sights to see, things of interest, and even restaurants that are worth eating at.
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.
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.
Mind mapping: a powerful brainstorming tool Whether youre a busy executive or a copywriter like me, mind mapping leads to a flow of thoughts. And by creating blank branches, youre forced to satisfy the brains desire for Gestalt, or wholeness, to find answers and make new associations. Where traditional note taking works in a constrained, linear way, mind mapping exploits the brains tendency to scan the whole field of information before it. Advantages of mind mapping for copywriters? So often, the simplest ideas and tools are the most powerful. For my work as a copywriter, Ive used mind mapping daily to plan articles, brochure content and website copy as well as for all manner of thinking and brainstorming purposes. Naturally, this article was planned using mind mapping.
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.
