Site Survey with a Drone: LiDAR vs Photogrammetry

Drones come handy when you need to explore the edifice or perform an inspection of the large area. Through aerial imagery, you can track the results of the construction process, detect deviations from the blueprints, or monitor the changes that have occurred during exploitation. There are many use cases, but all of them have one requirement in common—all works should be done with highly accurate geopositioning.

When it comes to getting a very detailed and accurate 3D model of the site or a building, facility operators and engineers use UAS combined with a camera or LiDAR. What are the differences between these technologies? And how can we enhance a project with a high accuracy level? Check out the new video from the Indiana Drones team to discover it.

Georeference Your Data with Reach Receivers

Besides getting the high-resolution data, you need to georeference your dataset correctly. To achieve it, you should place several ground control points on your worksites before the mission. 

That’s where Reach RS2 Survey Kit can save you a lot of effort. All you need is just a set of Reach receivers and checkered square plates. Coordinates of control points are recorded with the ReachView app available for iOS and Android devices. Just put your GCPs on the site, create a new project in the ReachView app, and collect the location. It’s that simple!
