What is the scale of the map in representative fraction?
Representative fractions are a unit-less relation between one “unit” on the map and how ever many “units” of the same type on the ground. An RF of 1:24,000 means one inch on the map equals 24,000 inches on the ground and one centimeter on the map equals 24,000 centimeters on the ground.
What are the 3 different ways to represent scale on a map?
There are three primary ways to indicate scale on a map: a representative fraction (e.g., 1:24,000), a verbal scale (e.g., “One inch to the mile”), or a graphic scale bar.
How do you convert representative fractions to scales?
To convert a Representative Fraction scale to a direct statement scale, divide the denominator by 100000, to change centimetres into kilometres.
What is RF in geography and its significance?
Answer: The ratio of distance on the map to distance on the ground is known as a representative fraction (RF).
What do you understand by RF?
Radio frequency (RF) is a measurement representing the oscillation rate of electromagnetic radiation spectrum, or electromagnetic radio waves, from frequencies ranging from 300 gigahertz (GHz) to as low as 9 kilohertz (kHz).
How do you teach map scales to students?
Have students work in small groups and use a large sheet of paper, pencils, and rulers to make a classroom map that is to scale. Have them measure the length and width of the room. Then have them make a scale to help them draw the map, such as 1 inch = 5 feet.
How do you explain a scale on a map?
Map scale refers to the relationship (or ratio) between distance on a map and the corresponding distance on the ground. For example, on a 1:100000 scale map, 1cm on the map equals 1km on the ground.
What is the advantage of expressing scale by Representative fraction?
One of the major advantages of using the R.F. (Representative Fraction) scale is that it allows you to directly compare the sizes of objects between different maps. Because the R.F. eliminates the use of specific units (such as inches, feet, miles, etc.), there are no complicated conversions needed.
How do you calculate map scale?
Here are four simple steps you’ll want to follow:
- Find a map of an area you want to use.
- Find both the actual and measured distances of two points on your map.
- Divide the actual distance by the measured distance on the map for your scale.
- Place your scale numbers on the map.
How can a map scale of 1 cm to 2km be represented in representative fraction?
1: 200000. (2) 1: 20,000. (3) 1: 2000.
What is the use of representative fraction scale?
(Representative Fraction) scale is that it allows you to directly compare the sizes of objects between different maps. Because the R.F. eliminates the use of specific units (such as inches, feet, miles, etc.), there are no complicated conversions needed.
