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.
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).
The OS Explorer map series is the most popular choice and an essential for longer or more complex walks or those going off the beaten track. It is highly detailed and shows all rights of way, footpaths, landscape and interest features and contours. Every house, public facility or point of interest is covered giving you all the tools you need to locate yourself as well as finding that nearest pub for a drink after a hard days walking! The scale is 1:25000 - that is 1cm on the map equates to 250m on the ground (4cm per km or 2 1/2 inches to a mile) The OS Landranger map series covers a wider area with a scale of 1:50000 (thats 1cm on the map to every 500m on the ground, 2cm per km or 1 1/4 inches to the mile). This makes it handy for planning a day out over a broader area and for getting a good picture of where you are going and it shows the main footpaths and rights of way as well as tourist information and points of interest. However it doesnt contain as much detail as the OS Explorer range and if you are going off into the wilds you will need the detail of the Explorer map to navigate with confidence.
Here are a few ways for you to spot a fake old map: 1. Color maps were hand-colored before the 1850s. With a magnifying glass take a close look at the color. If you see a matrix of small and even overlapping dots then you have a map made after the 1900s. Your map may say it is from the 1600s for example, but the presence of these dots means that it was not made until after the 1900s. Its a copy. 2. Old maps were mostly engraved on metal plates in reverse so that they could be printed. When printing the pressure from the press and its engraved plate into the paper leaves a "plate mark" or indentation around the map. If you have a plate mark on your map be sure to look all the way around to see if anything was printed beyond the plate mark. If there is printed material spilling beyond the plate mark, you have a fake.
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.
In addition to these places, another good source for obtaining various types of travel maps is by contacting the tourism office environment of your travel destination. They can be contacted through the internet or by phone. In addition to maps, they can likewise send other information regarding their destination. This can be very valuable to people who have never traveled to that specific place before. Retain mind, this source is normally best for people who have ample time to prepare their trip as it could take a short while to receive the requested maps. Travel agencies can also be very helpful in getting maps. They generally have a wide variety of maps, which might be included in brochures for certain destinations. If they do not have a certain travel map you must, they usually know where to go to get it owing to their large database of contacts.
