The process of establishing or developing intermediate points between two terminal points or end points on a straight line is known as ranging.
Direct Ranging: The ranging in which intermediate ranging rods are placed in a straight line by direct observation from either end.
Direct ranging is possible only when the end stations are intervisible.

Direct Ranging in Surveying
Direct ranging is a method of surveying used to measure distances between two points without using any intermediate points. In this method, the end stations must be mutually intervisible, which means they must have a clear line of sight to each other.
Importance of Mutually Intervisibility
The reason why mutually intervisibility is important for direct ranging is that it ensures that there are no obstructions between the two end stations. If there are obstructions, such as buildings or trees, the direct line of sight between the two stations will be blocked, and direct ranging will not be possible.
Limitations of Direct Ranging
While direct ranging is a useful method of surveying, it does have its limitations. These include:
- Distance limitations: Direct ranging is only effective for measuring distances up to around 1 km.
- Accuracy limitations: Direct ranging is not as accurate as other surveying methods, such as triangulation or trilateration.
- Weather limitations: Direct ranging can be affected by atmospheric conditions, such as fog or haze, which can reduce visibility.
Conclusion
In conclusion, direct ranging is a useful method of surveying for measuring distances between two points without using intermediate points. However, it is important that the end stations are mutually intervisible to ensure that there are no obstructions between them. Direct ranging has its limitations, including distance and accuracy limitations, and it can be affected by weather conditions.
