Uses and Characteristics of Conventional Surveying

Uses of Conventional Surveying
Chain Surveying:
  • Used for taking linear measurements in the field.
  • One-dimensional measurements.
  • Used for measuring directions of survey lines.
  • Used for measuring angles of survey lines – both horizontal and vertical angles.
  • 2-Dimensional measurements.
Dumpy level:
  • Used to (i) determine elevations of given points with respect to a given or assumed datum; (ii) establish points at a given elevation with respect to a given or assumed datum.
  • One-Dimensional measurement.
Plane tabling:
  • Graphical method of survey in which the field observations and plotting done simultaneously.
Characteristics of Conventional Surveying
  • Suitable for small to moderate areas of extent.
  • Intervisibility between survey stations required.  Therefore, range of work gets limited.
  • Can only be used during day time.
  • Cannot be used in all weather conditions.
  • Requires more man power to accomplish the task.
  • Takes more time to cover larger areas, i.e., time consuming process and therefore, owing to time limitation, the no. of points to be surveyed gets limited.
  • Pressure of finances.
