Land surveying helps in calculating the dimensions of any area on the earth’s surface. It’s a scientific process used by experts for the 3D mapping of the angles and distance between points of land and features. 

The professionals who carry out this procedure are land surveyors. They are well-versed in the different tools, technologies, and processes required to survey any parcel of land — regardless of the terrain — accurately. 

In the past, land survey projects were carried out manually or with basic equipment, which affected the quality of outputs. Now, however, laser technology has improved the accuracy of the results. So it’s not surprising that land surveyors prefer to use laser scanners for mapping their land surveying projects.

Faster Than Other Equipment

Land surveying used to take weeks — sometimes months — until a few decades ago. Now it can be completed in a few hours— or a day at the most. Laser scanners make it incredibly easy to collect data with 100% accuracy, which results in fewer field visits and reduced expenses. 

Additionally, at times when there is a shortage of skilled land surveyors, laser scanners can help organisations to complete various surveying projects on time. This frees up the rest of the workforce for other related tasks, therefore increasing productivity without exceeding the project budget. 

Easier to Operate

Taking accurate measurements of land or buildings with manually-operated tools is difficult, time-consuming and sometimes impossible. 

Some land is difficult to reach and even those areas accessible to surveyors can be tough to measure due to obstacles like rocks, trees, etc. In these situations, even if surveyors can carry out the mapping, the quality of the collected data may not be sufficient to create three-dimensional models of the terrain. 

This is where laser scanners are crucial because they can easily capture data and produce 3D mapping for any terrain — regardless of the obstacles.

Detailed Information about the Terrain

Besides their speed and ease of use, laser scanners can also produce a comprehensive view of land that is not otherwise possible. Standard, hand-held tools can often fail to capture a terrain due to its location — and only produce two-dimensional pictures when they do. 

Laser scanners, however, can produce three-dimensional images and create 3D models for detailed analysis — even in hard to reach places like caves or dense forests. 

Useful in Historic Preservation Projects

Laser scanners also play a vital role in creating non-intrusive, high-quality models of historic buildings to help plan renovations or repairs. Their accurate measurements ensure that surveyors can prepare three-dimensional maps and keep records that can be used in case of emergencies like flood, earthquake or fire.

Land surveying involves many different processes like aerial mapping and mobile laser scanning —processes that are next to impossible to carry out with standard tools. Laser scanners come in different types with unique functionalities that make it easy for land surveyors to map different projects on time and without exceeding their budget.

If you are a land surveyor or represent an organization that handles land surveying projects, start using laser scanners to collect high-quality data. This data, when put into TopoDOT’s comprehensive workflow, can optimize your operations as well as improve the bottom line of your business.

It’s good to know that land surveying is useful in preservation projects. That sounds like a great way to keep historical places safe. Maybe I can get a surveying company to look at my property just in case I need to preserve something.
