• Building foot print

• Pathways and landscape

• Parking and services

• Ground floor plan

What are the measurements taken in surveying

• Distance, height

• Angle and levels

• Distance, angle, levels, relative position and relative heights

• Relative heights and relative position

The survey in which the surface of the earth is taken as a curvature

• Plane survey

• Location survey

• Geodetic survey

• Reconnaissance survey

Tacheometric survey uses tacheometer device which measures

• Length in between two points

• angle between two points

• height difference between two points

Offset is the measurement

• Distance of the object from survey line which is perpendicular or oblique

• Horizontal distance from the object

• The line joining two survey stations

The equipment used to mark the sighting station is called

• Cross staff

• Ranging rod

• Clinometer

• Line ranger

Device which is used to establish line of sight is

• Tripod

• Alidade

• Bubble tube

• U frame

In plane table survey device which fixes the station on paper

• Alidade

• U frame with plumb bob

• Spirit level

• Trough compass

Principles of plane table survey

• Parallelism

• Centering

• Levelling

• Back sighting
