What is a cloud point survey?

A survey with a cloud point laser scanner is a method of meticulously examining an area to gather precise measurements and details. This scanner emits laser beams in various directions, recording the distance to objects and surfaces they encounter. As the scanner rotates, it creates a point cloud—a 3D representation of the environment with millions of points. These points accurately depict the shapes and contours of buildings, terrain, and objects.

How is this data used?

Architects, engineers, and urban planners use this data to assess existing conditions, plan developments, detect discrepancies, and ensure designs align with the site’s characteristics for effective decision-making and construction accuracy.

Cloud point surveys offer several advantages over traditional measured surveys:

  • Accuracy: Cloud point surveys provide highly accurate 3D data, capturing precise measurements of objects and terrain. This level of detail surpasses what is achievable with traditional methods, ensuring more accurate planning and design.
  • Efficiency: Cloud point scanning is often quicker than traditional surveying methods. It captures large amounts of data rapidly, reducing the time required for fieldwork and increasing overall project efficiency.
  • Comprehensiveness: Cloud point surveys capture comprehensive data of the entire surveyed area, including intricate details and features that may be overlooked in traditional surveys. This comprehensive data set allows for more informed decision-making during the design and planning phases.
  • Visualization: The 3D point cloud generated from cloud point surveys enables easier visualization of the surveyed area. Designers, architects, and engineers can visualise the site from various angles and perspectives, facilitating better understanding and communication of project requirements.
  • Safety: Cloud point scanning can be conducted remotely or from a safe distance, reducing the need for surveyors to physically access hazardous or hard-to-reach areas. This enhances safety on-site and minimizes the risk of accidents or injuries.
  • Future-Proofing: The digital nature of cloud point survey data allows for easy storage, retrieval, and sharing. It can be revisited and utilised for future projects, renovations, or maintenance, providing long-term value and eliminating the need for repeated surveys.

Overall, cloud point surveys offer superior accuracy, efficiency, comprehensiveness, visualization capabilities, safety enhancements, and long-term usability compared to traditional measured surveys.
