Topographic Survey with Drones
The topographic survey with drones, which is done at Pigra Engineering S. L., is an increasingly popular technique for the collection of topographic data. Drones equipped with photogrammetric cameras and laser sensors enable the collection of aerial imagery and accurate terrain elevation data.
To make a topographic survey with drones,in order to perform the survey, a drone equipped with a photogrammetric camera and image processing software is required. The drone must fly in a planned flight pattern to capture aerial images of the study area. Image processing software is then used to create a 3D terrain model from the captured images.
Surveying drones have become an essential tool for the construction and surveying industry due to their ability to obtain accurate and detailed data in a more efficient and affordable manner than traditional methods.
There are many surveying drones on the market, but some stand out for their high accuracy, image quality and ease of use.
Pigra Engineering S.L. offers a drone mapping service, that is used for the creation of accurate maps of an area. The data collected by the drone is used to create topographic maps, Ortho photos and 3D models. The aerial photogrammetric survey with a drone is a specialized technique that combines aerial photography with precise ground elevation measurement.
There are several drones available on the market that are suitable for surveying. Some of the best drones for surveying include the DJI Phantom 4 Pro, the DJI Mavic 2 Pro and the DJI Matrice 600 Pro. These drones have specific features for surveying, such as high accuracy and stability in flight.
In terms of accuracy, modern drones can achieve an accuracy of up to 2-3 cm in measuring ground elevation, but this also depends on the quality of the camera and the software used.
