SGC Surveying team welcomes new technology to help capture data more quickly and efficiently

We all know that utilising the latest technology can help achieve faster and more efficient results – and this is particularly true for our SGC Surveying business.

The team has recently taken delivery of a Microdrones md4-3000 with a new Mini vux3 sensor. The drone is primarily used for LiDAR flights and to collect pictures at the same time. LiDAR, which stands for light detection and ranging, is a remote sensing method that uses light from a laser, to measure ranges and distances.

By combining the LiDAR results and pictures, the team can build a seamless, updated picture that is georeferenced, and a 3D LiDAR point cloud created, all from one flight.

The data is used to create bare earth surface models of existing conditions, to create a 3D model of the top of a building for solar panels to be installed. It’s also been used to extract power line attachment points on high voltage transmission lines.

Mitchell Stewart, Party Chief/UAS Pilot with SGC Surveying, said: “We have used this method with Enbridge and Piedmont Natural Gas, Duke Energy, several land development companies and at an active gold mine site.

“The LiDAR drone helps to capture far more data much faster and efficiently than traditional means. We can take upwards of 200 million data points with our average site and combine that with some field verification data as well as any hard facts, to see areas from the air and create a seamless view of the area of interest. On larger areas, we are able to greatly reduce field crew time and help keep crews out of harm’s way.”

Mitchell added that as the unmanned aircraft systems (UAS) field continues to mature and gain acceptance with clients, the use of drones is expected to become much more widespread.

“We are always on the lookout for what is next as drones and technology are always changing and evolving and how they can be implemented into our workflow,” he said.
