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.
Very popular antique maps are fetching very high prices at the auction block, because of this many forgeries have appeared as well as numerous copies of these maps. Map reproductions are not worth anything regardless of what the seller tells you. We will give you a few tips to distinguish a fake antique map from a real antique map. First let us talk about copies, forgeries and reproductions of antique maps. Cartographers have copied each others maps for centuries and have improved on them as well. These old maps can be valuable since they were done when the information on them was valid and useful. They are genuine historical documents. However, recent copies of old maps that depict geographical information from centuries past are made with the intent of offering decoration and sometimes historical insight to their buyers. The value of these map reproductions is often marketed to unknowing customers by claiming that the copy is of a rare map or that is was made using some fancy printing technique. The truth is that a copy of a rare map is not rare, it is the original map that is rare. The copy is worthless and the same goes for the fancy printing.
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.
A world wall map can have a range of benefits, from the cultural and social to the geographical and educational. This article presents an overview of the cultural and social impacts that maps have on people. Childs Play Children love to use their imagination and play games where they pretend to be someone or something. Children can use world maps to pretend they live in another country and imagine what life would be like in a different continent, with a different climate and different neighbouring countries. It helps children to appreciate and understand that life may be very different in other countries to what they are familiar with. Countries near the equator will be hotter and there will need to be adaptations in living conditions. By looking at a world map, adults too can let their imagination run wild. Whether for planning a trip or a holiday or simply looking at the distance between countries, a wall-map of the world is key for sparking the imagination.
There are other options worth knowing about: firstly the Active Maps which come in both Landranger and Explorer ranges and have a laminated, waterproof cover to protect your map from the rain and elements when out and about; secondly there are the custom-made maps which allow you to choose where the centre of your map will be. These are particularly handy if the route you want to follow will require buying 2 or more maps or you want maps of the countryside surrounding one central point on all sides e.g. the area around a campsite or accommodation or even your house! Both types of map are more expensive than basic OS Explore and OS Landranger maps. Check your whole walk area is covered: Select the type of map you require and then check on the map detail that your whole route is covered. The last thing you want is to realise that half your intended route is missing when you set off for your walk! If necessary you will need to get additional maps for adjoining areas. Each map has a number in the top right hand corner of the cover which along with the name is the reference you will need to select the correct map to purchase.
The association map, in its simplest form, is just two keywords with a defined link. In terms of looks the diagrams are similar to a non-linear mind map, but structurally they have the more formal requirements of the concept map. The key point from a learning view, is that the relationship between the two keywords must always be clearly defined. A keyword may have many links to other keywords, but each pairing must have this well-defined link association. I have found the decisions one must make about these relationships have been some of the most useful in helping a student to overcome a misunderstanding, and in designing learning packages so that learners move more easily through a topic. Linking the unknown to the known has been a useful teaching strategy since time immemorial, and the association map is a particularly powerful way of tapping into this for some students.
