Any scale shows the ratio of size on the map (as an option – in the drawing) to the size in the real world. The scale can be reducing when the size on the map is smaller than real (as in the case of this issue), and they can increase when the size in the image exceeds the real size.
The ratio indicated on the cards shows how many real centimeters on the surface in 1 centimeter of the map:
Each centimeter on the map on Earth will correspond to a thousand centimeters (t.e. 10 meters)
Accordingly, in 1 centimeter of the card there will already be 10,000 centimeters on Earth (t.e. already 100 meters)
Another zero has been added and a hundred thousand centimeters on Earth are displayed in a centimeter of the card (T.e. a whole kilometer).
The scale of the card indicates the ratio between the distance on the map and the corresponding distance on the ground in the same measurement units.
For example, the scale of 1: 1000 will mean that 1cm on the map is 1000cm (10m) on the ground.
For large -scale maps 1: 100,000,000 1cm on the map corresponds to a thousand kilometers on the ground.
The considered options for the scale are called numerical. There are also:
- Linear scale.
On maps, plans, drawings, the image scale always indicates so that it can be understood what actual size on the terrain corresponds to the size on the map.
Here are the values indicated in the issue (for example, 1: 1000) belong to the scale of reduction.
And they mean the following:
-1: 1000-significant, 1 centimeter on the map is 1000 centimeters on the ground, or 1 cm = 10 meters.
-1: 10000 is when 1 cm on the map corresponds to 10,000 cm on the ground. 1 cm = 100 m.
-1: 100000- 1 cm on the map as many as 100,000 cm on the ground, or 1 cm = 1000 m = 1 km.
Well, you have already caught the scheme-it-out of the colon-the size on the map, and to the rightderivative.
The scale of the applied on Krata show how exactly the unit of measurement on the map with the same units of measurement on the ground is correlated, most often a centimeter is accepted per unit of measure, then it will become clear to us that 1 centimeter on the map is 10,000 centimeters on the surfaceEarth. Accordingly, the larger the larger, the less detailed map is obtained and the more area it is depicted and vice versa, the less the scale is the more detailed map and the smaller plot of land it describes. It may also be that different cards of the same area will have a different scale, but the size of the cards themselves will also be different. For example, a Russian map can be with a scale of 1: 10000000 – a huge wall card and with a scale of 1: 100000000 – such a card will fit in the atlas or book, and at the same time the details of these cards will be different, small settlements may well be displayed on the wall map, rivers and other details, but in the Atas on a map with a large scale, only the largest grandfathers (large cities, mountains or rivers) will be indicated.
This is a very necessary information, without which the card is no more expensive than toilet paper, you measure the distance from the station to the city with a ruler, multiply to scale, transfer to the necessary units and you know how much to go or stomp to the desired point…
These numbers show the ratio of the size of the card to real sizes. That is, on the map 1: 1000 1 centimeter will correspond to 1000 centimeters or 10 meters. And the larger the area of the territory that needs to be portrayed on the map, the greater the number on the left.
If on the map they write that the scale of 1: 100,000, then that 1 centimeter on it is 100,000 centimeters in a real area. That is, 1000 meters or 1 kilometers.
Such a card will no longer be as detailed as the previous option. After all, some of the objects will be simplified.
These numbers show the ratio. What’s what? The line of a certain length was measured on the map – this is the number 1, but in reality this distance will be 1000, 10000, 100,000, respectively, times more. So it turns out that only 1 mm of the line will give a real distance of 1000 mm (1 meter), 10000 mm (10 meters) or 100,000 mm (100 meters).
Such numbers reveal to us the ratio of the real size of the area, to the size that is issued in a reduced form of this very area, but already on the map. For example, the numbers are 1: 10000, show us that one centimeter on the map is equated with ten thousand centimeters on the real area of the Earth.
Everything is very simple. This scale shows the ratio of size on the map to real sizes. That is, for example, 1: 1000 means that one centimeter on the map corresponds to 1000 centimeters on the ground. 1000 centimeters are 10 meters, that is, 1: 1000 means that in one centimeter 10 meters.
The scale means how many times one distance is more than the other. For example, if you have a drawing of any scheme on a scale of 10: 1, 10 cm in the drawing corresponds to 1 cm of real size. It is important to note that the area of the scheme is not 10 times, but by 10^2, t.e. 100 times.
