A topographic survey is typically conducted on undeveloped land. Different from other types of land surveys, this survey aims to describe the shape, elevation change, surface roughness, contours, and overall three-dimensional features of the terrain. It includes various elements such as trees, roads, manholes, utility poles, and additional landscape features.

A marine survey, also known as a hydrographic survey, involves the detailed mapping of the underwater area at the bottom of a body of water. This survey assesses the depth of the water and identifies the volume of sediment located below the water surface. It plays a vital role in the dredging process, as it provides essential insight into the extent of sediment accumulation in the marine environment.

3D laser scanning serves as an exceptionally effective tool for three-dimensional imaging. This technology allows for the comprehensive three-dimensional capture of a specific area in X, Y, and Z coordinates without any physical interaction. By emitting a laser beam, the scanner produces a complete 360-degree image, resulting in a point cloud consisting of millions of individual 3D points.
