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.
The second thing selecting the best travel maps is to know the mean of transport you are going to use in case you are on an intercity trip or visiting many countries. Once youve got this information planned, it is the time to take the decision according to it. If you are planning to visit a single city, the best you can do is to get nothing at all. Im not speaking about going there with no information but what I really mean is that any city has very good maps you can take for free in any tourism office, hotel or simply at the airport or the railway station where you arrive. These maps are already thought for you, youll see the main streets, touristic attractions, etc. Instead, it is indeed important to look for the best travel maps if you are going to run across many cities.
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.
MapSignal application offers; zooming in entails one or a combination of: Real-time map messaging service (MapSignal) by a more detailed about Human generated signals (SingleG/GPassenger) (available/unavailable icons) enlarging the same map or enlarging the pixels, hence showing more detail by removing less information compared to the less detailed version enlarging the same map with the pixels enlarged (replaced by rectangles of pixels); no additional detail is shown, but, depending on the quality of ones vision, possibly more detail can be seen; if a computer display does not show adjacent pixels really separate, but overlapping instead (this does not apply for an LCD, but may apply for a cathode ray tube & Mobile Applications such as Cell phone, PDA, Smart Phone), then replacing a pixel by a rectangle of pixels does show more detail.
Electronic maps, From the last quarter of the 20th century, the indispensable tool of the cartographer has been the computer. Much of cartography, especially at the data-gathering survey level, has been subsumed by Geographic Information Systems (GIS). The functionality of maps has been greatly advanced by technology simplifying the superimposition of spatially located variables onto existing geographical maps. Interactive, computerised maps are commercially available, allowing users to zoom in or zoom out (respectively meaning to increase or decrease the scale), sometimes by replacing one map with another of different scale, centred where possible on the same point. Mobility satellite navigation systems are computerised maps with route-planning and advice facilities which monitor the users position with the help of satellites.
How to Read a GPS Mapping System The most common way for a GPS receiver to display your global location is with a plot screen, using a series of waypoints in the area. So that you can track your position logically, you should always set the plot screen directions so that north is up, or towards the top of your device so it reads like a map. The device will allow you to navigate through the GPS map, zooming in and out or even shifting the maps location. The GPS database will allow you to save various waypoints, typically at least one hundred, and label them with brief descriptions. Your waypoints and their names can help plan routes quickly in the future.GPS devices come with a map datum already installed. This is a basic representation of the land formations in the country or area where the unit was designed. GPS units manufactured in the United States are installed with North American map datum, so it is necessary to install additional software if the unit will be used outside the country.
