Civil engineering surveying is the process of determining the location and elevation of points on a piece of land. It's used to create plans and maps for civil engineering projects, such as bridges, dams, roads, and canals. 

Civil engineering surveying typically involves:
Measuring horizontal and vertical distances between points
Describing the characteristics of the land structure and surface
Using boundary surveys to detail the boundaries of a property
Using spherical trigonometry to find exact locations and reference points
Using geodetic surveying to take the curvature of the earth into account 

Surveying can involve using a number of pieces of equipment, including:
Chain
Tapes
Total Stations
Global Navigational Satellite Systems 

Some methods of calculating areas in surveying include:
Midpoint ordinate rule
Average ordinate rule
Simpson's rule
Trapezoidal rule
Graphical rule
