There are various types of levels such as dumpy level, Y level, cushing’s level, tilting level, cooke’s reversible level and automatic level instruments for leveling in surveying. The process of measuring vertical distances in surveying is called leveling.
1. OLDER TOPOGRAPHIC SURVEYING METHODS. This section provides an overview of the past and present instruments and methods used to perform topographic surveys of sites, facilities, or infrastructure.
There are five types of levelling instruments used in surveying such as dumpy level, tilting level, cushing’s level and cooke’s reversible level.
A level is an instrument giving horizontal line of sight and magnifying the reading at a far away distance. It has a gravity-based provision, a bubble, to orient the telescope. It consists of the following parts: •A telescope to provide a line of sight •A level tube to make the line of sight horizontal and
