Chain Surveying Process in Civil Engineering


Chain Surveying Chain surveying is the simplest method of surveying. In this survey only measurements are taken in the field, and the rest work, such as plotting calculation etc. are done in the office. This is most suitable adapted to small plane areas with very few details. If carefully done, it gives quite accurate results. … Read more
