Surveying & Earthwork Design: 

Stadia Distance - Level
  • Calculate distance by stadia measurement from survey rod readings and a level sighting.
Stadia Distance - Inclined
  • Calculate distance by stadia measurement from survey rod readings and an inclined sighting.
Instrument Height
  • Calculate instrument height (HI) for a topo survey.
Point Elevations - Level Sight
  • Calculate point elevations for a topo survey with a level sighting.
Point Elevations - Inclined Sight
  • Calculate point elevations for a topo survey with an inclined sighting.
Volume - Average End Area
  • Calculate earthwork volume by the average end area method.
Volume - Grid Square
  • Calculate earthwork leveling by the grid square method (also called borrow pit leveling).
Traverse - Leg Distance
  • Calculate the distance or length of the leg of a traverse.
Traverse - Leg Azimuth
  • Calculate the azimuth of the leg of a traverse.
Traverse - Lat. and Dep.
  • Calculate the length and departure to a vertice point of a traverse.
Traverse - Area by CM
  • Calculate the area of a traverse by the coordinate method.
Earthwork Problem 1
  • Calculate the storage volume of a proposed stormwater detention pond and the excavation haul volume given the soil bulking factor.
