CHAIN SURVEYING

Chain surveying is a method of survey of land wherein only linear measurements are made and no angular measurements are taken.
Chain surveying is used for small ground areas with simple details (natural or the man-made features like buildings, rivers, trees, tower etc.).
It is the simplest method of surveying and consists of measuring the lengths of the lines marked on the ground/field.
In order to perform chain surveying, only a chain or a tape is required with few ranging rods.
However chain surveying is not possible for large areas with too many details.
Chain surveying is used for marking the boundaries and other details of land for preparation of maps.
