  • Leveling - directly or indirectly measuring vertical distances
  • Level surface - curved surface
  • Level line - curved line
  • Horizontal surface - plane that is tangent to a level surface
  • Horizontal line - straight line in horizontal plane
  • Vertical line - parallel to the distance of gravity
  • Meansealevel - imaginary surface of the sea
  • Datum - parallel with mean sea level
  • Elevation - vertical distance above or below mean sea level
  • Differenceinelevation - difference between two level surface Iin which the pointz lie
  • DirectorSpirit leveling - common method in determining the elevation of points some distance
  • Reciprocal leveling - accurately determining the difference in elevation between two intervisible points
  • Trigonometric leveling - employed in determining by trigonometric computation
  • Profile leveling - used to determine differences in elevation between two points at designated short measured
  • Stadia level - combines features of direct leveling with those trigonometric leveling
  • Barometric leveling - determining the difference in elevation between points by measuring the variation in atmospheric pressure
  • Cross-section leveling - short profiles at right angles
  • Borrow-Pit leveling - determining the relative elevation
  • Dumpy Level - is the most widely used direct leveling instrument
  • Wye level - very indetical to the dumpy level
  • Builder's level - used in different phases of building construction
  • Automatic level - self leveling features
  • Tilting level - can be tilted
  • Lasers level - use of lasers
  • Hand level - surveys involving short sights where a low order of accuracy is sufficient
  • Geodetic level - basically another type of tilting level
  • Transitasalevel - refered to as the universal surveying instrument
