Conformal projection: These projections maintain angular relationships and show accurate shapes while covering small areas. Such maps are useful for navigational or meteorological purposes where angular relationships are important. Equidistant projection: Maps that maintain accurate distances along given lines or from the center of the projection are based on this principle of equidistant projection. Such maps are used for navigation and for radio and seismic mapping. The Equirectangular projection and the Equidistant Conic projection are two examples of this category. Azimuthal (or zenithal) projection: A projection that maintains accurate angular relationships and directions from a given central point use this projection. Maps for aeronautical purposes use this principle. The Lambert Azimuthal Equal-Area projection and the Gnomonic projection are examples of how azimuthal projection is used for map making.
Many but not all maps are drawn to a scale, allowing the reader to infer the actual sizes of, and distances between, depicted objects. A larger scale shows more detail, thus requiring a larger map to show the same area. For example, maps designed for the hiker are often scaled at the ratio 1:24,000, meaning that 1 of any unit of measurement on the map corresponds to 24,000 of that same unit in reality; while maps designed for the motorist are often scaled at 1:250,000. Maps which use some quality other than physical area to determine relative size are called cartograms. A famous example of a map without scale is the London Underground map, which best fulfils its purpose by being less physically accurate and more visually communicative to the hurried glance of the commuter. This is not a cartogram (since there is no consistent measure of distance) but a topological map that also depicts approximate bearings. The simple maps shown on some directional road signs are further examples of this kind.
The walk location is decided, you know how long you want to be out for and youve brushed up on your map reading skills. Its time to get a map and plot the route. In the UK this means using an Ordnance Survey map which shows all the footpaths, features and topographic detail you will need to complete any forray into the countryside safely and successfully. There is not just one Ordnance Survey map for each area however but a choice of different series of maps, all showing different levels of detail, scales or usages. So how do you select the right Ordnance Survey map for your walk? Here are a few pointers to help you choose: Select the correct map for your walk: You have two main choices of paper map - the Ordnance Survey (OS) Explorer or the Ordnance (OS) Landranger. Other maps are available such as street atlases, historical or specialised activity maps but for hiking or walking you will need one of the above in order to provide enough detail to navigate from.
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.
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.
