What is refractive fraction?

What is refractive fraction?

Answer: The ratio of distance on the map to distance on the ground is known as a representative fraction (RF). 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, then RF can be expressed as 1: 24,000.

What is a representative fraction scale on a map?

: a map scale in which figures representing units (as centimeters, inches, or feet) are expressed in the form of the fraction 1/x (as 1/250,000) or of the ratio 1:x to indicate that one unit on the map represents x units (as 250,000 centimeters) on the earth’s surface.

How does representative fraction help in drawing?

What is the representative fraction? Explanation: The scale of the drawing is given as 15:1 that is an enlarging scale, this means dimensions are increased to 15 times of actual ones. So the representative factor is that dimension in drawing to actual dimension. R.F.

What is represent a fraction?

A representative fraction (RF) is the ratio of distance on the map to distance on the ground. In fact, on some maps, you will see the RF represented using a division sign. A representative fraction indicates ratio between the number of units on the map to the number of units on the ground.

What are different kinds of map?

8 Different Types of Maps

  • Political Map. A political map shows the state and national boundaries of a place.
  • Physical Map.
  • Topographic Map.
  • Climatic Map.
  • Economic or Resource Map.
  • Road Map.
  • Scale of a Map.
  • Symbols.

What is the formula for representative fraction?

Representative fractions are expressed in the form of 1 followed by a : (colon) and then a number, where the one is the numerator in the fraction, the colon represents the division operation, and the other number is the denominator. Thus, a scale of 1:24,000 can be expressed mathematically as 1/24,000.

How are representative fractions represented on a map?

In fact, on some maps, you will see the RF represented using a division sign. A representative fraction indicates ratio between the number of units on the map to the number of units on the ground. 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.

What are the characteristics of a reactive system?

Reactive systems have certain characteristics that make them ideal for low-latency, high-throughput workloads. Project Reactor and the Spring portfolio work together to enable developers to build enterprise-grade reactive systems that are responsive, resilient, elastic, and message-driven.

How is the scale of a representative fraction ( RF ) expressed?

Thus, a scale of 1:24,000 can be expressed mathematically as 1/24,000. In fact, on some maps, you will see the RF represented using a division sign.

When are representative fractions invalid in ArcMap?

Representative fractions are invalid if the map is reduced or enlarged. An advantage of adding RFs to your map is that they are extremely easy to determine in ArcMap – simply look at the Map Scale text on the to bar menu of the ArcMap interface.
