A representative fraction is the scale shown in a map as a ratio. Top Answer. This RF scale means that 1 unit on the map represents 50 000 of the same units on Earth's surface. A line of 1 meter length is shown by 1 cm on the drawing sheet. Graphic map scale: Fractional map scale: The fractional method for portraying the scale of a map uses a representative fraction to describe the ratio between the map and the real world. Representative Fraction is also known as Numerical Function. Share 7. Statement of Scale: The scale of a map may be … Bar Scales. Bar scales show scale using a … Asked by Wiki User. See Answer. Scale is often represented as a ratio between the real world size and the size in units on the map. Representative Fraction: It is a method of scale of a map or plan expressed as a fraction showing the ratio between a unit distance on the map or plan, and the distance measured in the same units on the ground. Its RF will be_____. By convention, the proportion is expressed as a "representative fraction" in which map distance (D m) is reduced to 1. A Direct statement scale uses words to describe the relationship between a distance on a map and a specific distance on Earth's surface. RFs may be shown as an actual fraction, for example 1/24,000, but are usually written with a colon, as in 1:24,000. An RF is a ratio and is shown as follows: 1:50 000. 2009-01-03 06:40:01. Large scale maps will have a RF of 1:50,000 or greater (i.e. There are three main ways that scale is indicated on a map: graphic (or bar), verbal, and representative fraction (RF). (Recognizing the symbols and colors used, identifying directions and distances). In this case, the ratio existing between the length on the map and actual length on the ground is indicated by a fraction whose numerator is always 1. The proportion, or ratio, is also typically expressed in the form 1 … 1/25,000) is a larger fraction than a small scale map which would have an RF of 1/250,000 to 1/7,500,000. The length and width of the field, on the map is 10 cm and 8 cm respectively. A representative fraction, or RF, shows the relationship between one of any unit on the map and one of the same unit on the ground. Other scale types - click on each phrase to go to the detailed glossary entry. Its representative fraction (RF) is _____ 1/100 16 The size of the letter is described by its _____ height 17 The area of a field is 50000 m2. 1:10,000). This fraction is usually abbreviated as R. F. Thus, Representative Fraction (R.F.) Wiki User Answered . A large scale map refers to one which shows greater detail because the representative fraction (e.g. 13 14 15. Map scale is the proportion between a distance on a map and a corresponding distance on the ground: (D m / D g). (c) Reading and using statement of scale, graphic scale and scale shown by representative fraction method. reading and using statement of scale,graphic scale and scale shown by representative fraction method Share with your friends. (It could also be shown as l/50 000, but this form is not as common.) (No drawing work, only explaining their meanings). How Scale is Shown on a Map. This can be shown as 1:50, 000 or 1/50, 000. Representative Fraction (RF) Scale The third method for showing scale is the representative fraction scale. Reading and using statement of scale graphic scale and scale shown by representative fraction method? Maps are often known as large scale or small scale. 1/2500 18 A representative ratio of 500,000:1 shown on a map means that one unit of distance in the map equals 500,000 units of distance on the territory.
