Operations in surveying

Operations in surveying consists of

1) Planning

To decide

• the methods to be adopted for surveying

• the resources (instruments & personnel) to be used

• the control points / stations to be used ( those already available and/ or to set up)

• The planning operation needs a-priori field visit and this is known as reconnaissance.

2) Field Observation

It involves

• Collection of field data by making necessary measurements

• Recording of observed data in a systematic manner.

• Before starting any field observation, the permanent adjustments of all the instruments need to be checked thoroughly by trained personnel and if required, it must be adjusted.

3) Office Works

It involves

• Processing, analysing and calculation of observed data

• Preparation of necessary data (for making plan or map of the area)

• Making of a plan or map of the area

• Computation of relevant field parameters as per design for setting out engineering works at site.

4) Setting out Works

• To locate and establish different parameters / dimensions at the site as per design for further engineering works.
