Triangulation surveying is a method used in the field of geodesy and engineering to determine the relative positions and distances of points over a given area. It involves creating a network of triangles, where the baseline of one triangle is precisely measured, and the angles of the triangle are observed to calculate the remaining sides. […]

Tunnel surveying is a specialized form of underground surveying essential for the construction of tunnels. It involves detailed procedures and the use of specific equipment to ensure accuracy in aligning the tunnel’s center line and maintaining its level. This article explores the methods and procedures of tunnel surveying, highlighting the steps, tools, and considerations involved.

Drone mapping, also known as aerial surveying, has revolutionized the construction industry. By capturing detailed site data, drones produce essential deliverables in the form of maps, which aid in planning, monitoring, and decision-making. There are two primary methods of drone mapping: Photogrammetry and LiDAR. Each method provides unique outputs and requires specialized data processing software.

Leveling is a crucial process in surveying, involving the measurement of vertical distances to determine the relative heights of different points. To perform leveling effectively, specialized instruments called levels are used to focus on and read the required measurements.
