Today’s civil and construction engineers need access to the right information at the right time in order to support fast, accurate and efficient work. In order to get the visibility they need, engineers depend on engineering support services like land surveying.
In the past, land surveying was a time-consuming process that could seriously delay an engineer’s work. However, there are new technologies in use today that enable engineers to get the visibility and information they need quickly, by significantly speeding up the land surveying process.
Read on to learn more about some of these surveying technologies and to find out how you can put them to work for your organization.
Laser Scanner Surveying
High definition scanning is an innovative technology that allows land surveyors to create detailed representations of a terrain and structures without having to individually visit each point of interest on the job site. Laser scanner surveying helps engineers do their jobs better by providing a more detailed deliverable, and doing it much quicker than a traditional land survey. With terrestrial laser scanning, a process that once took months can now be completed in a matter of a few days, making sure that engineers never have to wait to get the information they need.
High definition scanning, also referred to as LiDAR, works by bouncing laser beams off the terrain and recording a point everywhere the laser hits a surface. Once the area has been scanned, the result is a “point cloud” made up of millions of different points. These millions of points represent a level of detail that engineers could never dream of seeing in the past.
Once a professional land surveyor has collected data using high definition scanning, they can use those data points to create a survey-grade 3D model of the area. Using this extremely detailed model, engineers are able to get an up-close look at the terrain, without having to waste time by traveling the location themselves.
3D modeling from the point cloud gives engineers a more detailed and accurate look at the terrain and structures they’re going to be working on, and does so in a fraction of the time required to complete a traditional land survey. Also, these models can be used to help inform the survey documents that will drive the entire project forward, ensuring that engineers and all other key stakeholders will always have the information they need right at their fingertips. It’s really no wonder that so many engineers are excited about the possibilities of using 3D modeling as an engineering support tool.
Finally, today’s engineers no longer have to be limited to terrain visibility that is captured from ground level. Using either fixed-wing aircraft, helicopters, or UAV’s, a professional land surveyor has the ability to conduct aerial mapping. This technique can work using a variety of different scanning methods, including the high definition laser scanning described above.
Unlike aerial photography, which merely provides a visual of what the terrain looks like from above, aerial mapping can give engineers a detailed 3D rendering of the terrain, displaying every crack and hole in astonishing detail. Since aircraft have a far greater range of visibility when operating from above than land surveyors do when operating from ground level, aerial mapping can allow quick and efficient scanning of a large area, making it the perfect technology to use on very large engineering projects.
