It can also mean the measuring and mapping out of the position,size and boundaries of an area of land.

Importance of land surveying

  1. Area of land: Land surveying helps to determine the area of a place e.g market,school,garden.
  2. Position of construction: It helps to set on the ground the position of construction or any engineering works.
  3. Production of maps: It can also help to determine the production of maps.
  4. Position of certain features: land survey can also be used to determine the relative positions or features of the earth(natural or artificial)so that they may be correctly presented on maps.
  5. Feasibility studies: Land surveying can be used as basis of feasibility studies in any construction work to be carried out on the surveyed land.
  6. Land security: Land surveying gives the owner of the land security which can be used to obtain loan as soon as certificate of occupancy(c of o)is given.


Branches and types of land survey

There are different branches of land survey.They are:

Topographical surveys : In topographic surveys,the survey works are based on the different locations of the main,natural or artificial features of the earth,such as rivers,hills,valleys etc.

Engineering surveys : These surveys include all aspects involved in the preparation of engineering works  to its execution.The features are channels,roads,dams,rail etc.

Geodetic survey: These are high accuracy surveys mainly concerned with the shape of the earth position,fixing of points which provide control for lower accuracy survey
