The accuracy of a drone survey depends on the project requirements. For many projects, an acceptable error of 30 cm will be enough in terms of accuracy, whereas for others, maximum acceptable error of 2 cm is required. Get in touch with us to discuss your needs.
Drone mapping uses a technique called photogrammetry. The way this works is that a drone captures a large range of overlapping photos of an area, showing the same point from various different angles. This allows us to create a high-resolution 3D map that includes information on elevation and height as well as shape, texture and colour. Find out more on our Photogrammetry Surveying page
Professional drones can easily cover hundreds of square kilometers for high-resolution maps. The main restrictions are flying time/battery capacity and permits.
Because of drones, it has become easier than ever to map large areas. Just a few years ago, the only real way to get an aerial photogrammetric map with sufficient accuracy and resolution was a manned aircraft. Today, drone 3d mapping is a cost-effective and quick way to map large buildings and areas.
