Establishing Traverse, Benchmarks, Fly Level and Ground Control Points
Traversing involves creating a series of interconnected lines using GPS equipment and Total Station surveying instruments. This process is essential for mapping out large areas of land accurately. During traversing, a series of points are established on the ground, which are then used to create a network of lines. The lines are then used to create a boundary and topographic features for the survey area.
Fly levels are differential level measurements that help determine the difference in elevation between two benchmark points. This process is essential for ensuring that the survey area is mapped out accurately, and the results are reliable. Fly levels are typically carried out using a surveying instrument known as a level, which is used to measure the height of the benchmark points.
In addition to benchmarks and fly levels, ground control points are also established during the surveying process. Ground control points are known points on the ground that are used to calibrate detailed topographic survey / lidar survey / aerial surveys. This process is essential for ensuring that the data collected during aerial surveys is accurate and reliable.
These points help stabilize the survey boundary, ensuring the surveying standards are maintained and the results are precise. Without these points, the survey team would struggle to accurately map out the survey area, leading to unreliable results.
