Laser Scanners can capture topography and ground conditions of a large areas
The laser scanner can be used to measure the topography and ground conditions of a large area in a fraction of the time needed with traditional methods. It can also be used to collect data for calculating volumes. This type of device is often used in engineering, architecture, surveying and construction.
The laser scanner reduces the time and cost needed for surveying an area, as it can produce digital models of the terrain in real-time.
Topography captured for an area of over 23,000 square meters
In this project, we surveyed an area of over 23,000 square meters, including details of all the excavations, pilecaps, and site boundaries to represent site topographical conditions and calculate the volume of each excavation. The survey was also georeferenced to site-specific coordinates so the point cloud could be superimposed to the design model and contour lines and level would reflect site coordinates and levels.
In this case, the point cloud was also georeferenced to site-specific coordinates so the point cloud could be superimposed to the design model and contour lines were drawn with levels reflecting site coordinates.
Laser scan reduce time and costs for topographical survey
The site survey was completed in less than a day, and the BES team worked on post-processing to classify the cloud and remove unnecessary points, create contour lines, calculate volumes, and show ground spot levels to a grid specified by the client. In addition to the traditional 2D CAD survey, the site can now access laser-scan data (point cloud) and a free viewer. These tools provide a precise representation of the site condition at a specific point in time. The point cloud is available to all members of the team with free software.
