Surveyors use a variety of methods to determine the elevation of different points in a specified area.

Leveling is the branch of surveying in which the height of specific points throughout an area are determined. This information is used to inform engineers of the terrain so that they can figure out what needs to be done in order to prepare a site for construction or paving. There are several different types of leveling that can be performed to gather the necessary data. The best part is that at Y Rock Trucking, we are equipped to take care of your leveling needs. Once completed, we’re already familiar with your project and we can proceed directly to site grading.

Types of Leveling
The type of leveling used when surveying a site will depend on the lay of the land and what obstacles are present, such as bodies of water. There are four main types of leveling: direct leveling, trigonometric leveling, stadia leveling, and barometric leveling.

  • Direct leveling is the most common type of leveling used when surveying an area. Measurements are directly observed from the leveling instrument. Direct leveling is divided into six different types of leveling: simple leveling, differential leveling, fly leveling, profile leveling, precise leveling, and reciprocal leveling. Each method has its own applications, depending on the distance between the points being measured and whether or not there are obstacles present.
  • Trigonometric leveling involves using trigonometric relations of certain angles and the horizontal distance in order to find the elevation of a specific point. It is sometimes called indirect leveling.
  • Stadia leveling is a modified form of trigonometric leveling. The Tacheometer principle is used to determine the elevation of a point. This type of leveling is the most suitable for surveying hilly terrains.
  • Barometric leveling uses a barometer to measure the atmosphere at a given altitude. The atmospheric pressure is measured and compared at two different points. This method only provides a rough estimate of elevation and is not used very often.
