advantages and disadvantages of representative fraction (RF) scale
Answers
Answer:
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.
It is helpful in terms of comparison of two defined objects, but this fraction may not always true when viewed the map in either large or small scale.
Explanation:
The representative fraction (RF) scale is commonly defined as the ratio between any two places on the map and on the actual ground surface. They are also known as the map scale and are given on the bottom of the maps. It helps in understanding the size of an area. For example, a scale of 1:25000 says that 1 cm on the map is equivalent to 250 meters on the ground surface.
The advantages of this scale are-
- It helps in understanding the size of an object, relative distance between any two distinct places can be determined.
The disadvantage of this scale are-
- It is represented in the form of a fraction where there is no use of any units. So, the exact distance cannot be calculate. The maps when viewed in large or small scale, the representative fraction gets affected.
