Though a globe model of the earth is the most common version of the earths surface, it would often create a lot of confusions to combine the political and physical maps together. Thats why maps are created for different purposes, which use map projection to depict the earths surface on a plane using a wide variety of scales. Digital maps also use map projections to present data on a computer screen. Different maps use different map projections based on what purpose the map will serve and the scale thats suitable for the purpose. For example, a type of map projection may show severe distortions while mapping the whole country, but may serve as an excellent choice for a countys detailed map that aims to cover a large area. The type of map projections also influences some of the design elements of a map. While some are suitable for small regions, some other projections are good for mapping areas with a huge north-south or east-west extent, or to cover all countries of the world.
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.
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.
Maps of places give details as to the geographic location, physical characteristics, climate profile, vegetative structure, flora and fauna, soil structure, latitude and longitude, etc. Over the years, these maps were used in schools and colleges, offices and in houses for the purpose of education and/or reference. These maps used to be in paper-printed two-dimensional formats. Now three-dimensional, interactive or dynamic maps represent more accurate and up-to-date information. The art and science of map-making is called cartography. Maps are created representing political, geographical and other particular aspects. Most of the maps are drawn on a scale, say 1: 10,000, meaning that one unit of measurement on the map represents 10,000 units on the land. Maps depicting land areas are called political maps or physical maps. Political maps show land boundaries or territorial boarders between states and provinces, say those between India and China or Maharashtra and Gujarat. Physical maps depict geographical features such as terrain structure, mountains, deserts, plateaus, rivers, land under use, etc.
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.
