World maps are a mere sketch of the entire world cataloged as 'political' and 'physical'. The political map is meant to illustrate territorial borders while the physical map shows the geographical features, which demonstrates the physical surface of the earth. World maps are the ones that give you a clearer picture about continents like Asia, Africa, South America, North America, Antarctica, Europe, and not to mention Australia. Whether it is a globe or an atlas you will know which country lies in which part of the world to say the least.
World maps are two-dimensional, geometrically exact depiction of a three-dimensional space. You must also know that the technique of map-making is called cartography. The beginning of map-making can be traced back to the Stone Age and seems to predate written language to say the least. You can find maps tinted on a wall of the Catal Huyuk settlement in south-central Anatolia, presently in Turkey.
World maps are basically conceptual depictions of the world and not nonaligned documents. This is why they should be cautiously construed. Nowadays, road maps are probably the most convenient and shape a division of navigational maps comprising aeronautical and nautical charts, hiking and bicycling maps and railroad network maps. The major number of drawn map sheets are constituted by local surveys, carried out by municipalities, utilities, tax assessors, emergency services providers, and other local agencies.
As a matter of fact you will find several but not all maps drawn to scale. However a “drawn to scale" report helps the reader invariably to conclude not only the real sizes but also the distances in between the represented things. In fact, a bigger scale is more detailed, hence settling for a bigger map to correspond the area is advisable.
Maps are so poised for the hiker that they are scaled at the ratio 1:24,000. It just goes to show that 1 of any unit of measurement on the map matches up to 24,000 of the identical unit in actuality. On the other hand, for a motorist, maps are scaled to about 1:250,000. However, commercial navigational maps like road maps and town plans give up o the accuracy in scale by bringing about the a greater visual expediency to its user.
There are topographical maps also, which represent invariable values like for instance average temperature. These are depicted together with other things depending on the scale of the map in the shape of Isolines.
World maps are informative and in fact it is a quite a learning material for students as they tend to learn so much about the different countries, the continents, the different physical features, pressure zones and what not.
