Unique. Fast. Accurate. Aerial geotechnical investigation

In sections where the plane could not take measurements - under bridges and works of art - Lot 10 deployed the car. In this way it was able to hand GelreGroen a very complete picture. Not only of the road, but also of the 500-meter strips to the left and right of the existing roads.

Plot 10 collected the data within a week and processed it within six weeks. "After this, we were able to provide GelreGroen with valuable products," says Stefan Brouwer, salesman, surveyor and co-owner of Lot 10. "GelreGroen received a so-called combined 'point cloud', overview photos and oblique images of the area. From the collected data, a Digital Terrain Measurement according to NLCS layer structure was provided. The data for this were collected partly with LiDAR measurements from the aircraft and partly with LiDAR and 360° camera from the car." The driven and flown data made Lot 10 available through its own online data portal.

Fast and accurate

Lot 10 is the only party in the Netherlands that uses aircraft for geodata collection. "Gathering data from aircraft is very fast," Brouwer says of this. "In addition, the measuring technique deployed is among the most accurate land surveying techniques at the moment. The measurement results are accurate to within a few centimeters. That is also why GelreGroen chose us."

Combining measurement data

"It was a fun job. Everything we offer, we were able to apply here. We combined the various measuring techniques. Survey photos were taken that GelreGroen can use well as a substrate in drawing programs. We took vertical and 45° aerial photos with which GelreGroen can look at objects from any wind direction at an angle of 45°, so that signs also become readable. As a result, our approach offers many advantages for governments, contractors and engineering companies. Permission is required, but there are no restrictions to perform our work - anywhere. We also tackle areas such as airports, heavy industry and nature reserves effortlessly and do not have to be closed off."
