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.
Reach RS2+ / RS3 for Placing GCPs
Both Reach RS2+ and Reach RS3 are a great fit for setting the GCPs in RTK mode. Control points locations are recorded with the Emlid Flow app available for iOS and Android. If you want to choose a receiver that will fit your project, go to the page about GCPs for drone mapping.
