Sea level gives a reference point. Sea level is 0 so from there we can determine the height of land and whether that land is prone to flooding.
there are commonly five tpes of levelling:- 1.simple levelling 2.differential 3.reciprocal levelling 4.profile levelling 5.cross section levelling
thue advantages and dis advantages of levelling
differentiated by the set of instrument, observation methods and accuracy.
of Level
Ordinary spirit levelling uses a spirit level to measure height differences between points, whereas precise levelling involves more precise instruments like a digital level or automatic level to achieve higher accuracy in measurements. Precise levelling is typically used for engineering and construction projects that require more accurate measurements.
Surveying levelling is crucial in architectural works as it ensures accurate measurements of land and structures, which is essential for proper design and construction. It helps in determining elevations and gradients, preventing issues related to drainage and structural stability. Additionally, precise levelling aids in the alignment of buildings and infrastructures, ensuring that they meet safety standards and aesthetic guidelines. Overall, it enhances the quality and durability of architectural projects.
