3D Laser Surveying – For Land Surveyors, GPS is Out, and Laser Scanning is In

Laser scanning technologies have undeniably transformed and revolutionized land surveying. While land surveyors still find traditional techniques useful in some cases, the majority of land survey work nowadays are conducted using newer technologies and more efficient and accurate methodologies such as 3D laser scanning. Armed with laser scanners that collect data down to the smallest data points, surveyors nowadays enable the planning and execution of more efficient and accurately measured projects, while helping clients analyze very specific components of sites. This kind of accuracy allows them to make more informed decisions at every stage and step of projects.  Below are more reasons why 3D laser surveying makes a better choice of technique over more traditional survey technologies:

  • 3D laser surveying produces faster results – With older GPS technologies, field surveys take days or weeks to complete, especially when dealing with complex sites. Laser scanning technologies allow surveyors to complete similar types and magnitudes of field surveys in significantly smaller time frames (usually within a day or two). Laser scanning also allows complete fly throughs and the creation of detailed 3D models, animations, and graphic presentations in less time.
  • 3D surveys are cheaper – Because scanning can be completed faster, surveys also take less resources as fewer field visits are needed in order to collect data efficiently. This reduces overall project costs, while increasing the speed and accuracy of data collection.
  • 3D lasers collect highly accurate data3D laser scanning technology is the most accurate technology for collecting field data to date. This means the ability to create a more solid knowledge base for planning better projects.
  • 3D laser scanners are extremely versatile tools – Laser scanning technologies are applicable to many different aspects of land surveying. In fact, many land survey companies rely on laser scanners not only for producing detailed topological maps and making volumetric calculations, but also for creating 3D models, 2D drawings, and enabling precise analysis for budgetary and timeline preparation, and application implementation of projects.
