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.
3. Hold the map up to the light to look at the paper. Most maps made before the 1820s were made on hand-made paper. This paper was made by artisans who used a wire mesh to hold up the paper pulp. This wire mesh leaves a visible grid called "chain links" that are visible against a strong light source. Paper makers often had a watermark to identify themselves that is sometimes visible on bigger maps. If you dont have chain links on a map dated from the 1820s or earlier, then you have a map reproduction. 4. The majority of antique maps were taken out of old atlases, because of this there is often a fold in the middle of a map. This fold is where the map was bound in the book. Also atlas maps are worn from use at the corners, especially the right hand top or bottom corners. This is where most people would flip the pages. If your map doesnt have a center fold or looks too new, then it probably is.
Map projections are classified based on: Distortion characteristics: Some projections often need to show a particular area or its relative size accurately for distributions or other phenomena. These are called equivalent or an equal area projection. The Lambert Azimuthal projection that maps a sphere to a disk, and accurately shows all regions of the sphere is an example of this category. However, this equal area projection fails to represent angles with accuracy. The Albers projection is another instance of equal area map projection that utilizes two standard parallels. Despite no preservation of scale and shape, the distortion in this case is found to be minimal between the standard parallels.
There are various Mumbai maps available in the market which can be used according to ones needs. The various kinds of maps include- Road map, railway map, tourist map, excursion map, local map. The road map of Mumbai will give you all the significant information that you may require about the most important roads of Mumbai. If you are travelling by train, the railway map is a perfect guidance which will assist you throughout the whole journey. The railway map of Mumbai stretches from Bhayander in the northern part of the city (which further connects to Surat), to the Chhatrapati Shivaji Terminus (VT) in the southern part of the city. Many other stations apart from the 2 extreme stations mentioned above are included in the railway map of Mumbai such as Thane, Church Gate, Andheri, Kandivali, etc. The tourist map of Mumbai is a highlighter of all the public visit places that are important from the tourist point of view including The Gateway of India, Iskcon Temple, Sidhi Vinayak Temple, Essel world, Water kingdom and many more. As we all are aware that Mumbai is a very important place from tourist point of view, so if you are planning a holiday in Mumbai then a tourist map is a must.
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.
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.
