How has 3D Laser Scanning Improved Land Surveying?

Before buildings were constructed, people had to conduct surveys to study the land: its boundaries, precise measurement, topography, slopes, and the location of nearby existing infrastructure. The builders would then plan the project based on the data gathered from the survey.

These land surveys took weeks, even months to finish, depending on the size of the land. Land surveyors used a theodolite to do the measurements. It was a useful tool that triangulates the location of any point using basic trigonometry, but its process was long and tedious.

Today, however, 3D lasers allow land surveyors in Utah and various parts of America to accomplish their tasks in just a few days, regardless of the land size. All it takes is a thorough laser scan of the land, and an accurate three-dimensional image of that property appears on a computer for the surveyor to study.

Time-efficient and accurate, what else can 3D lasers do to improve land survey efficiency?

3D Lasers: Precise and Efficient Measurement

3D lasers improve land survey efficiency by reducing fieldwork, versatility, and measurement precision.

  • Reduced Time on the Field

Studies show that the existence of 3D lasers reduced fieldwork time for land surveyors by 50-70 percent. Theodolites take several weeks to complete measurements, whereas the 3D laser scanning process takes a few days or less to accomplish a task, saving time and speeding up construction projects.

Using 3D lasers cuts down on labor costs. This allows surveyors to spend less time on the field and spend more time analyzing the data instead.

  • Versatility

3D lasers also allow accurate measurement from places that are impossible or too dangerous to measure. Scanning equipment can reach any surface with relative ease. 3D lasers make water depth assessments and aerial measurements easy.

Additionally, laser scanners also come in a variety of different types and platforms. Land surveyors can easily switch equipment, depending on what the surface requires for accurate measurement. A 3D laser is versatile and malleable to most environments in getting the job done.

  • Measurement Precision

3D laser scanning allows the precise measurements of any space. A single scan can provide detailed models of any scanned surface. High-definition image scans of the property also reduce the risk of design errors.

Land surveyors don’t have to rely so much on manual work to pinpoint the exact measurement of a plot of land. 3D laser scanners render an exact match of a piece of scanned land, reducing the probability of human error and mistakes in design later.

3D laser scanning makes the lives of surveyors easier by reducing the time they need to be out doing fieldwork, providing precise and accurate scale replicas of the land or surface they need to measure, and helping them reach hard to measure areas because of its specially designed equipment. And with efficient planning and construction, companies may reduce labor cost and maximize their profits.

Land surveyors are the first ones on any construction site. With 3D lasers, they can provide the critical information that architects and engineers need to design and build accurate, safe structures.
