# Advice 1: As a scale to determine distance on a map

The terrain on the map is always shown in reduced form. The reduction factor is called a scale. By measuring the length of a line on the map, you can then calculate the actual distance between two objects on the ground.

If you want to know the distance between two points in a straight line, measure the corresponding segment on the map with a ruler. Preferably, it was made from thinner sheet material. In the case that the surface on which the spread out map is not flat, to help tailor the meter. In the absence of a thin line, and if the card is not a pity to puncture, is convenient to use for measuring the compass, preferably with two needles. Then you can transfer it to graph paper and measure the length of line on it.

The road between the two points on the map are rarely straightforward. Measure the length of curved line will help the device - odometer. To use it, first roller rotation to align the arrow with zero. If the odometer is electronic, set it to zero manually is not necessary - just press the reset button. Holding the roller, press it to the starting point of the segment so that risk on the housing (located above the roller) was pointed right at this point. Then keep the roller on the line while the risk will be combined with the endpoint. Read the testimony. Be aware that some of the curvimeter there are two scales, one of which has a graduation in centimeters and another in inches.

Locate on the map pointer of the scale - it is usually located in the lower right corner. Sometimes this pointer consists of a segment of calibrated length, next to which shows to what distance it corresponds to. Measure the length of this cut line. If you find, for example, that it has a length of 4 centimeters, and next to it is specified that corresponds to 200 meters, divide the second number by the first, and you'll learn that each centimeter on the map equals 50 meters on the ground. On some maps instead of a cut there is a ready-made phrase, which may be, for example, as follows: "an inch is 150 meters." Also the scale can be specified as a ratio of the following type: 1:100000. In this case, it can be estimated that one centimeter on the map corresponds to 1000 meters on the ground, as 100000/100(inches per meter)=1000 m.
4
Measured with a ruler or odometer distance, expressed in centimeters, multiply by the specified on the map or the calculated number of meters or kilometers in one centimeter. The result is the actual distance, expressed respectively in meters or kilometers.

# Advice 2 : How to calculate scale

On any geographical map you can see about the following inscription: "Scale 1:100 000". Usually the first number is 1, and the second may vary. If it isn't there, then definitely there's a little Ticker, divided into equal periods, or nomogram. These signs designate the ratio of the size of an object on the map or plan to its real size.
You will need
• Tape measure or surveyor's compass
• Line
Instruction
1
If you have a plan, which accurately plotted the various objects and you need to find out the extent to which the plan is made – start with measurements. Select the object that is nearby. Obmerte him on the plan and record the results.
2
Measure the actual object. Use the tape measure. In order to avoid mistakes, make the peg and hook a loop of tape. Hammer a stake into the ground so that the zero mark roulette was at the starting point of the length or width of the object.
3
Define the scale. The only record of its figures. Note the size of the object on the plan, then the one that happened when measuring on site. For example, you have got that barn 5 metres in length on the plan is 2, 5 cm. Move the meters to centimeters. So you have 2, 5 cm containing 500 cm. Calculate how many centimeters of the territory contained in 1 cm on the plan. For this larger number, divide by less. Receive 2.5:500=1:200, i.e. 1 cm in the plan corresponds to 2 metres on site.
4
In order to determine the scale more accurately, take a few measurements. For example, obmerte barn on the site and distance from the gate to the pond. Plans are different, and the size of an object can be applied not accurately. If there are discrepancies, take another measurement. The image of the object that does not match the other two, adjust the plan.
Note
The larger the scale, the smaller the denominator, where it is recorded. 1:100 is more than 1:2 000.

To measure an object easier with a helper. If there is no helper, and the peg by hand was not, firmly push the tape measure against the wall of the object. It is most convenient to measure on the ground – for example, on the bottom of the wall.

# Advice 3 : How to determine distance on a map

Any map is a reduced representation of some territory. A coefficient indicating how much the image is reduced in relation to the real object is called a scale. Knowing him, it is possible to determine distance on the map. For real maps on paper to a scale value fixed. For virtual, e-cards, this value varies with the zoom of the map on the screen.
Instruction
1
If your card is on paper, find its description called a legend. Most often, it is thermochem design. The legend must contain the map scale, which will tell you how much measured in centimeters distance on this map will be in reality on the ground. So, if the scale is 1:15000, this means that 1 cm on the map equals 150 meters on the ground. If the map scale is 1:200000 1 cm, pending it is 2 km in reality
2
Measure the distancethat interests you. Note that if you want to determine how fast you can walk or drive from one house to another city or from one settlement to another, then your route will consist of straight line segments. You will not move in a straight line, and trails along streets and roads.
3
In fact, the distance between the start and end point of your path is longer than the distancemeasured between the start and end points of the path. The measurements were accurate, put on the map the route of your movement in the form of short and long straight lines, determine their amount and find out actual distancethat you need to overcome.
4
To determine distance via the map, you can use one of the many GIS programs that you can find on the Internet. There are specialized programs used by the transport company. By setting the start and final destination, town, you can get a card which will be caused to route your route and it shows the total distance and the distance between the nodal points of the route.
5
Distance on the map can be measured using the Ruler tool GIS packages, Google Earth and Yandex Maps, the underlying cause for the cards which are space satellite images. Just select this tool and click on the point that marks the start of your route and where it will be finished. The distance value can be learned in any given unit of measure.

# Advice 4 : How to calculate scale

Scale drawing, map, diagram or image is the ratio of the linear dimensions of objects carried on them to the actual dimensions of the same objects on the ground or in kind. If that diagram, engineering drawing or map, then, usually, the indication of scale is required for such documents. But sometimes it so happens that the scale is not known, so it is necessary to define independently.
Instruction
1
Just in case, check, maybe you just did not notice this inscription. In diagrams and drawings it should be listed in the stamp. This may be a sign of a complete format "1:20 Scale" or abbreviated "1:20". On topographic maps and schemes of the indication of scale is also a required element Saramago clearance. It can be specified in the header of the card, which is located at the top or bottom. Sometimes the inscription, showing the scale is in the text of the map legend or directly on it. Carefully review the diagram or map.
2
If you can not find the instructions of the scale in the diagram, the engineering details or construction plan that identifies the size details in inches or measurements in meters, you can determine the scale yourself. Measure the dimensions on paper usual line in millimeters or fractions of an inch. Divide the value specified on the diagram, expressed in millimeters or inches, that you got when measuring. This will be the denominator of the desired scale of the drawing or plan.
3
In a similar way you can find the map scale or topographic scheme. You should carefully look at the map and define a couple of characteristic objects located on the terrain. For maps of large scale, this can be buildings, tubes of boiler. For maps and schemes on a small scale you can use the tops of hills and mountains, a fork in the road, other characteristic points of the relief and terrain. Measure with a ruler the distance map between these characteristic objects.
4
If you have a map of the same area with known scale, measure it the distance between the same feature points and make a conversion scale. If no such card, then use the mapping services of Google or Yandex. Find this area on satellite images, which are the basis of these services and define in it the same characteristic points which you found on the map or the diagram. Select the Ruler tool, measure the images distance and calculate from these data and measured on the map the distance scale of your map.

How to find out distance between point A and point on Google map? A painfully familiar question, isn't it? With the help of the map service Google is quite easy to determine the distance to a little-known town on the other side of the world or how far from your home is the nearest bus stop.

In the case where it is necessary to measure distance from point “A” to “B”, in one locality, should act according to the above scheme. The difference lies only in the fact that the name of the area you want to add a street and possibly the house number by a comma. ( For example, “A”: Moscow, Tverskaya 5, and V: Moscow, Tsvetnoy Boulevard, 3).
