Maps are so ubiquitous that we forget that we use maps on daily basis. The signage, the road mile stones, the directions that ask are basically maps in the making. Yes we make maps in our minds. Once you put these on paper or on electronic media, these become hard copy or soft copy maps. Maps basically fall in two categories, the raster and the vector maps. Raster maps are images of paper maps, it can be said to be similar to photographs. Can you edit them, yes but very difficult to control each aspect of raster maps layout and designs. Then how do we edit the maps and control all design and layout aspect? The answer is vector maps, these are intelligent maps which are basically made of three entities, points, lines and shapes. The points are symbols of hospitals, schools etc. The lines represent all entities which are denoted by paths like roads, railways, streams, contours etc. The area or shape comes in for parks, large water bodies, and even your home or office building if is a small scale map. Yes small scale map; smaller the scale larger is the detail on the map.
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.
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.
Interactive map making software usually supports custom definable regions, areas and location points. Users can select pre-designed flash map templates, and easily change color settings of countries or counties, and pinpoint locations on the map by using pushpin buttons or icons. A hover over tooltip box can be displayed with your own text, images, with links to another web page, PDF documents, or sites on the World Wide Web. As the main purpose of these maps are for navigation or data representation purpose, geographical details such as highways, buildings, rivers are not always necessary, which makes the map cleaner and easier to navigate by visitors. With few click-through on the national, state or county map, visitors can quickly find information or be redirected to specific page about a particular location on the map image.
A world wall map can have a range of benefits, from the cultural and social to the geographical and educational. This article presents an overview of the cultural and social impacts that maps have on people. Childs Play Children love to use their imagination and play games where they pretend to be someone or something. Children can use world maps to pretend they live in another country and imagine what life would be like in a different continent, with a different climate and different neighbouring countries. It helps children to appreciate and understand that life may be very different in other countries to what they are familiar with. Countries near the equator will be hotter and there will need to be adaptations in living conditions. By looking at a world map, adults too can let their imagination run wild. Whether for planning a trip or a holiday or simply looking at the distance between countries, a wall-map of the world is key for sparking the imagination.
Many but not all maps are drawn to a scale, allowing the reader to infer the actual sizes of, and distances between, depicted objects. A larger scale shows more detail, thus requiring a larger map to show the same area. For example, maps designed for the hiker are often scaled at the ratio 1:24,000, meaning that 1 of any unit of measurement on the map corresponds to 24,000 of that same unit in reality; while maps designed for the motorist are often scaled at 1:250,000. Maps which use some quality other than physical area to determine relative size are called cartograms. A famous example of a map without scale is the London Underground map, which best fulfils its purpose by being less physically accurate and more visually communicative to the hurried glance of the commuter. This is not a cartogram (since there is no consistent measure of distance) but a topological map that also depicts approximate bearings. The simple maps shown on some directional road signs are further examples of this kind.
