What is a fractional scale on a map?
The representative fraction (RF or fractional scale) is a ratio between the distance on the map and the distance on the real earth.
What is an example of a fractional scale?
1. Fractional or Ratio Scale: A fractional scale map shows the fraction of an object or land feature on the map. This type uses a set of numbers that represents the object or a landmark. As an example on the left photo, the orange-shaded scale represents a 2/3 fractional scale.
Which scale on the map uses both ratio and fraction?
Representative Fraction (RF) – Fractional Scale – Ratio Scale: 1:50000 represents the map scale as a mathematical ratio or fraction, thus the name ratio scale or fractional scale.
What is a linear scale on a map?
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. A verbal map scale expands abbreviations to describe a landmark or an object.
What does 1 250000 mean on a map?
For example, your map has a scale of 1:25 000, 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).
What are the three types of scales?
Three Types of Scale:
- Fractional or Ratio Scale: A fractional scale map shows the fraction of an object or land feature on the map.
- Linear Scale: A linear scale shows the distance between two or more prominent landmarks.
- Verbal Scale: This type of scale use simple words to describe a prominent surface feature.
How to determine map scale?
How-To Steps Use a ruler to measure the distance between the two places. Find the scale for the map you’re going to use. If the scale is a verbal statement (i.e. If the scale is a representative fraction (and looks like 1/100,000), multiply the distance of the ruler by the denominator (100,000 in this case), which denotes distance in the ruler
What does the scale on a map tell us?
Most maps include something called a scale to show how much smaller the map is. The scale shows how distances on the map are related to the actual distances. Map scale can be shown in a number of ways. The simplest way is a graphic scale. A graphic scale is a ruled line or bar that is usually marked off in miles or kilometers.
What is the purpose of a map scale?
The purpose of a map scale is to help the user to know the distance between 2 or more cities or geographical elements .
What is an example of a map scale?
Map scales may be expressed in words (a lexical scale), as a ratio, or as a fraction. Examples are: ‘one centimetre to one hundred metres’ or 1:10,000 or 1/10,000 ‘one inch to one mile’ or 1:63,360 or 1/63,360 ‘one centimetre to one thousand kilometres’ or 1:100,000,000 or 1/100,000,000 . (The ratio would usually be abbreviated to 1:100M)
