There are plenty of interactive map sites available online - including Google Map, Yahoo Map, Bing Map, Microsoft MapPoint, Mapquest, and many more. They are mainly used as directions tools, for road mapping and route planner. Type in an address or zip code and you will be able to find its exact location, including nearby buildings, parks, bars, restaurants, coffee shops, hotels and information about how to get there. But there are many other possible applications that website owners can make use of interactive maps for their particular industries and markets. There are many interactive mapping software which can help you to take advantage of geographic-related data, and to effectively visualize territory and business information by creating your own custom interactive maps.
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.
The monetary value of many antiques is based on what a prospective buyer is willing to pay for them, so the value of antique maps will vary. There are plenty of people who are willing to pay high prices for old maps, so their potential value is very high, depending upon their condition, the year in which they were produced, and many other factors. There are old maps that are worth two hundred dollars each and old maps that are worth thousands of dollars each. Small details can make all the difference. Finding Antique Maps Many of the best antique maps are part of historical and private collections. Maps are not the most durable antique items in the world, so there are only so many antique maps available today. The further back anyone goes historically, the harder it will be to find old maps from that time period. One of the reasons that old maps are so valuable in the first place is the fact that they are so rare and so fragile. They are tiny pieces of history that can be easily lost and can easily fade with time.
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.
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.
