The elevation of a point is determined through leveling and is designated as reduced level (R.L). It is being carried out using level and staff. For each set up, the level has to be temporarily adjusted. To start any project the permanent adjustment of level should be checked and rectified, if required. Diffrential leveling is used to find the difference in elevation; profile leveling is done to obtain profile along a longitudinal section; reciprocal leveling and trignometrical leveling are implemented to find the reduced level under specific field conditions. Different types of errors and mistakes are associated with leveling. These can be removed or minimised by using appropriate physical model or by adopting necessary precautions.
