Measuring chain, also
known as surveyor chain is mainly used for measurement of linear
distances.
Features
The important features are :
- Usually made of good quality steel.
- Prone to damage and wear.
- They have good stability and are lightweight.
Factors affecting the use of Survyor Chains :
- Measurement of the distance is confined to the length of the
chain, usually 50 or 100 meters.
- Accuracy of the distance measured is dependent on correct field
procedures and often the application of corrections for various
factors.
- End points of the distance to be measured needs clear paths of
travel, unimpeded by physical obstacles.
- Large undulations in ground level can make chaining difficult.
Utility of Measuring Chain
- Surveyor chains can be used for measuring distances for a wide
variety of survey purposes like length of a base line between two
survey stations.
- Used for setting out a chain line as part of a chain and to carry
out offset surveys like detail mapping etc.
Application
Survey chains are mainly used for measuring linear distances. Some of
the areas where they find application are :
- Detail Mapping
- Land Surveys
- Topographic Surveys
