Geographic maps are abstract representations of the world. It is, of course, this abstraction that makes them useful. Lewis Carroll made this point humorously in Sylvie and Bruno with his mention of a fictional map that had "the scale of a mile to the mile". A character notes some practical difficulties with this map and states that "we now use the country itself, as its own map, and I assure you it does nearly as well". This concept is elaborated in a one-paragraph story by Jorge Luis Borges, generally known in English as "On Exactitude in Science". Road maps are perhaps the most widely used maps today, and form a subset of navigational maps, which also include aeronautical and nautical charts, railroad network maps, and hiking and bicycling maps. In terms of quantity, the largest number of drawn map sheets is probably made up by local surveys, carried out by municipalities, utilities, tax assessors, emergency services providers, and other local agencies. Many national surveying projects have been carried out by the military, such as the British Ordnance Survey (now a civilian government agency internationally renowned for its comprehensively detailed work).
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.
Mapmakers and GPS manufacturers all have their own system of creating maps, but most maps begin with the placement of governmental sites, like fire and police stations, schools, and similar community landmarks. Aerial images and satellite photos are then layered into the basic map, along with any important additions that may be needed, to display the GPS map seen on the device. Some GPS mapping devices can produce immediate graphics of your location and surroundings, making it possible to view a real-time map that changes as your location changes. This type of GPS map is great in emergency situations.The features of GPS maps vary. Most software includes maps of cities, along with the major highways. These maps may also include city level streets, rivers and waterways, and even less traveled side roads. Many GPS mapping systems include features that make it possible to obtain maps from your computer, making it easy and convenient to travel to any area.
Some possible applications using interactive maps on websites including: Retail Shops / Branches Locator: A web-based interactive flash map can help your customers to find the nearest retail shop or branch location in few mouse clicks. For example, you can use an interactive map of United States on your website, with pushpin buttons to pinpoint all your retail shops, hotels or any other type of facilities. Your visitors can make selection simply by clicking on a pushpin button, and then he can see the list of options available including address and contact details. Interactive Real Estate Map: A real estate website can use interactive flash maps to display available properties on state, county or city maps. Push pins of different colors and shapes can be used to pinpoint residential properties, commercial properties, resorts, apartments, corporate offices, and more. Hover over effects can be included which can provide additional pop-up information about a particular property.
Some libraries carry the Sanborn maps on microfilm. Look up your property on the various maps and check for any existing house and outbuildings, such as a garage, shed or barn. The house number will be located at the front edge of the lot. Make note of the number as it was not unusual for the house number, or even street name, to change over the years. If you can find your property on a succession of maps, you can see how it changed over time. The fire insurance maps were updated somewhat irregularly, based upon the likelihood that enough had changed to make possible the sale of updated maps. However, when found, they can offer proof of the existence of your home and represent a unique snapshot of the community. Looking at maps can provide you with a unique perspective about the property you are researching, and can often offer new leads in your search for who lived in your home. Whenever you are at a library, government center or historical society, ask about the maps and atlases that are held in their collections.
There are some maps that combine all the above mentioned principles or use a compromise between them to depict the world and countries. For example, Robinson projection that showed the entire world at a glance can be said to be a compromise between the equal-area and conformal map projection. The objective behind its creation was to show the entire globe as a flat image. However, the Robinson projection was replaced later by the more modified version called the Winkel tripel projection, which is considered to be a blend of the azimuthal Aitoff projection and the equirectangular projection. At present, digital maps use either one or more than one of these aforesaid map projection types to create interactive maps that not only show the data in a much reliable way but also let the users utilize the maps to get additional information based on add-on clickable icons, pushpins, tool tip or mouse over info boxes etc. If you still havent enjoyed the use of digital flash maps with several user friendly, interactive features, its time to shift from the traditional paper maps to see the sales graphs soar.
