Questions?!

Datum If a whole series of heights is given relative to a plane, this plane is called a datum, In topographical work the datum used is the mean level of the sea (MSL) Definitions

Questions?!

Definitions Vertical Line Level Surface Level Line Line of Sight Horizontal Line

Vertical Line at a point The line formed by the string of a plumb bob when the tip is located directly over the point. Horizontal Line at a point The straight line perpendicular to the vertical line at that point Level Surface The continuously curved surface that is perpendicular to the direction of gravity at all points. Definitions

Vertical Line Level Surface Level Line Line of Sight Horizontal Line

Level Line A line that lies on the level surface. Difference in Elevation between two points The vertical distance between the two level surfaces passing through these two points Line of Sight or Collimation Neither horizontal nor level. Affected by atmospheric refraction. Definitions

Vertical Line Level Surface Level Line Line of Sight Horizontal Line

Bench Mark A marked point whose elevation has been accurately measured. Control Point A marked point whose coordinates has been accurately measured. Height of Instrument The line of Collimation above the datum after setting up the level above a certain point Definitions
