Linear Scale: A linear scale shows the distance between two or more prominent landmarks. The linear scale on maps is a set of lines or dots that represents a landmark. An example on the left photo is a map using a linear scale on each road.
What is a linear scale in geography?
Linear scales are also called bar scales or graphical scales. Linear scales have a distinct advantage over other map scales because they are printed on the map, and the proportions stay the same if the map is enlarged or reduced during reproduction. To use a linear scale, measure the distance on the map that you want to convert.
What is scale on a map?
On most maps, a scale is usually represented as a straight line divided into several numbered units. This is called alinear scale or bar scale. It helps you to find how far one place is from another. It also helps you to measure distance along roads, railways and other linear features on the map. Figure 3.3: A linear scale
How do you use linear scale to measure distance?
Linear scale. A person using the map can use a pair of dividers (or, less precisely, two fingers) to measure a distance by comparing it to the linear scale. The length of the line on the linear scale is equal to the distance represented on the earth multiplied by the map or chart's scale.
What is the length of the line on the linear scale?
The length of the line on the linear scale is equal to the distance represented on the earth multiplied by the map or chart's scale.
What is a linear scale example?
KEy POINTS number lines, the gauges on measurement scales, and the axes on graphs are all examples of linear scales.
What are the 3 types of scales on a map?
Generally, scale is a form of size. Map or cartographic scale is the ratio of a distance on Earth compared to the same distance on a map. There are three types of scales commonly used on maps: written or verbal scale, a graphic scale, or a fractional scale.

0:044:24How to use a Map Scale to Measure Linear Distance - YouTubeYouTubeStart of suggested clipEnd of suggested clipSome maps use a word statement to express scale for example one centimeter equals one kilometer.MoreSome maps use a word statement to express scale for example one centimeter equals one kilometer.
What is linear scale and how does it work?
The scale uses the change in distance to determine the position of the object. When the encoder reads the distance traveled, it translates the linear motion into a digital signal which shows measurements like speed, angle, or position.
How do you draw a linear scale?
To construct a linear scale, you will need to convert the range of frequencies that each band of radiation covers for the logarithmic scale. This will allow you to compare the width of the bands of radiation relative to each other.
What are the 2 types of scales?
There are two types of scales used in geography: map scales and relative scales. Each has a very different function, yet both also can work together.
What are different types of scales?
The four types of scales are:Nominal Scale.Ordinal Scale.Interval Scale.Ratio Scale.
What is linear scale question?
Linear scale question allows users to provide a numeric response to a statement or a question. You can assign the standard points or assign weights for each answer and calculate the score.
How do you find the scale of a line?
If the scale is a verbal statement (i.e. "1 inch equals 1 mile"), determine the distance by simply measuring it with a ruler. For example, if the scale says 1 inch = 1 mile, then for every inch between the two points on the map, the real distance on the ground is that number in miles.
What type of scale is a linear scale?
Linear Scale: A linear scale shows the distance between two or more prominent landmarks. The linear scale on maps is a set of lines or dots that represents a landmark. An example on the left photo is a map using a linear scale on each road.
What are the types of linear scale?
There are two basic types of linear scales: magnetic and optical.
What is the definition of a line scale?
Definition of line scale : a scale in front of a typewriter platen against whose vertical lines typed characters may be aligned and against whose top edge paper and typing may be straightened.
What are the different types of scales used in a map?

What are different types of scales?
The four types of scales are:Nominal Scale.Ordinal Scale.Interval Scale.Ratio Scale.
What are the types of maps?
According to the ICSM (Intergovernmental Committee on Surveying and Mapping), there are five different types of maps: General Reference, Topographical, Thematic, Navigation Charts and Cadastral Maps and Plans.
Which type of scale should be used on a map?
What are the two types of scales used in maps? There are two types of map scales, bar and lexical, but bar scales are used more frequently because they represent the distance ratio visually instead of in words, as is the case with lexical scales.
What is a linear scale?
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. A scale bar is common element of map layouts. On large scale maps and charts, those covering a small area, and engineering ...
What is the length of a line on a linear scale?
The length of the line on the linear scale is equal to the distance represented on the earth multiplied by the map or chart's scale. In most projections, scale varies with latitude, so on small scale maps, covering large areas and a wide range of latitudes, the linear scale must show the scale for the range of latitudes covered by the map.
What scale is used for nautical charts?
One of these is shown below. Since most nautical charts are constructed using the Mercator projection whose scale varies substantially with latitude, linear scales are not used on charts with scales smaller than approximately 1/80,000. Mariners generally use the nautical mile, which, because a nautical mile is approximately equal to a minute ...
When did Dutton use linear scale?
Dutton used both terms in 1978. The International Hydrographic Organization 's Chart No. 1 uses only "linear scale". The British Admiralty's Mariner's Handbook uses "scale" to describe a linear scale and avoids confusion by using "natural scale" for the fraction defined at scale (map).
How to measure distance on a map?
A person using the map can use a pair of dividers (or, less precisely, two fingers) to measure a distance by comparing it to the linear scale. The length of the line on the linear scale is equal to the distance represented on the earth multiplied by the map or chart's scale.
What is a Map Scale?
But regardless of the size of the mapped area, maps themselves must be represented on a smaller surface, like a piece of paper or a computer screen. That's where the map scale becomes a factor. A map scale is the mathematical ratio between a small unit of measurement on a map, like a centimeter or inch, to the corresponding real-world unit of distance, like a kilometer or a mile.
Where is the scale on a map?
The map scale is often located at the bottom of the map and is generally placed in an area that tends to be free of a lot of other symbols and lines. Sometimes they are placed over bodies of water, while other times the map may have bevels or borders around the scale. Some maps might even have the scale located in the map key.
Why do map scales work?
For that reason, map scales work more as a reference than they do as an accurate indication of travel distance. Map Scale Examples. Map scales can be found on all kinds of maps from road maps to public transportation maps. Some map scales are more useful than others.
Why is scale important in maps?
Map scales are important because even with technology, a map must be contained in an image small enough to be viewed all at once. Since maps can be found in a range of sizes, from a large atlas to a small screen, it's important for the person viewing the map to understand how the scale works.
How does scale work on a map?
Roads are curving and don't follow straight lines. On top of that, many roads go through or around larger metro areas and can involve lengthy detours. For that reason, map scales work more as a reference than they do as an accurate indication of travel distance.
How has cartography changed?
Modern cartography has changed a great deal with the invention and implementation of GPS and satellites that circle the globe taking pictures. Modern technology has automated much of the map making and scaling, allowing for maps with pinpoint accuracy.
What is the art of making maps?
Cartography is defined as the art or science of making maps. The practice of map making dates back over 18,000 years. The earliest examples of human-made maps are ancient cave paintings depicting maps of the stars that were found in the area of the world now known as Turkey.
