Bar scale also known as scale bar linear scale or graphical scale visually shows the relationship between distances on the map and the real world. In mathematics a linear map also called a linear mapping linear transformation vector space homomorphism or in some contexts linear function is a mapping between two vector spaces that preserves the operations of vector addition and scalar multiplication.

For example on a 1100000 scale map 1cm on the map equals 1km on the ground.
What is a linear scale on a map. To make this map a more convenient. The scale of a map shows how much you would have to enlarge your map to get the actual size of the piece of land you are looking at. To measure distance on Google Maps you can use the bar scale found on the corner of the map.
Linear scales are also called bar scales or graphical scales. A linear scale is usually present on most maps. The linear scale on maps is a set of lines or dots that represents a landmark.
If you understand the map scale number thats great but if you find that tricky you can still measure distances accurately. For example your map has a scale of 125 000 which means that every 1cm on the map represents 25 000 of those same units of measurement on the ground for example 25 000cm 250 metres. Learn basic calculations concerning the scale in maps.
Map Scales Linear Scale. A linear scale is a line which is divided into equal parts. How to calculate the distance in reality from the distance on the map and vice versa.
Usually more than one bar scale is shown on the side of the map each using a different unit of measurement. When you measure a distance on the map just compare it to the scale and it will instantly tell you the real world distance. For example the scale shows the map distance that equals 10 kilometers in real distance.
Liquidity L hospitals rule. A bar scale with the nominal scale expressed as both 1cm 6km and 1600 000 equivalent because 6km 600 000cm The scale of a map is the ratio of a distance on the map to the corresponding distance on the ground. A map of an area 100 miles long by 100 miles wide drawn at a scale of 163360 would be more than 8 feet square.
Linear Scale Scales generated with marking on a line for the purpose of detect actual measures of lengths on map are called linear scale. A linear scale is also called a bar scale scale bar or graphic scale. Map scale is often confused or interpreted incorrectly perhaps because the smaller the map scale the larger the reference number and vice versa.
What is a map scale. The larger the number the smaller the scale sounds confusing but it is easy to understand. This simple concept is complicated by the curvature of the Earth s surface which forces scale to vary across a map.
A linear scale shows the distance between two or more prominent landmarks. The scale of a. Click to see full answer.
A linear scale also called a bar scale scale bar graphic scale or graphical scale is a means of visually showing the scale of a map nautical chart engineering drawing or architectural drawing. Distance is different for each scale. Hereof how do you use a linear scale on a map.
A scale bar is common element of map layouts. The larger this second number is the smaller the scale of the map. At the bottom of each map theres a scale that indicates the distance on the map.
The sub part of linear scale at the left is further divided into sub parts which show smaller units of distance more accurately. It tells us how much map distance represents a certain real distance. It is used on maps to show the relationship between a particular distance on a map and the actual distance on the earth.
Map scale refers to the relationship or ratio between distance on a map and the corresponding distance on the ground. On linear scales the part on the left side of 0 is in use to measure minor lengths. Map Scales Ratio Scale A ratio scale will almost always be found on maps.
A straight line measuring about 15 cm or 6 inches divided in various parts shows the scale in linear method. It is quite easy to show distances on scale representing actual distances. In geography a linear scale is a bar or line graphic that shows the distance on the map that is equal to a real-world distance such as 100 miles.
