42 Megapixels / 0.7 cm (0.3 in) GSD
High-resolution aerial imagery
Get large coverage, high image quality and accuracy all at once
Thanks to its high payload capacity, the WingtraOne mapping drone is able to carry a wide range of high-end cameras. Its flagship camera is the Sony RX1R II, a 42 MP full-frame camera that captures incredibly detailed, high-resolution imagery. This resolution makes it possible to achieve more precise orthomosaic maps than ever before and to map larger areas with the very same accuracy.
20 MP vs. 42 MP camera
Due to the limited payload weight they can carry, multicopters and standard fixed-wing drones can only be equipped with 20 MP cameras. Thanks to its VTOL capability, the WingtraOne can take a 42 MP full-frame camera on board. The resulting high resolution images pay off with a lower GSD and striking resolution lines.
Higher resolution means better accuracy
During post processing, the coordinates are defined for each pixel on the map. And the ground sample distance (GSD) is also defined by how much ground is captured by a single pixel. Thus, the more pixels there are, the more accurate the final map can be. For example, if you fly with a GSD of 3 cm (1.2 in) /px , this is also the best possible absolute accuracy.
The WingtraOne mapping drone and the 42 MP Sony RX1RII sets a new benchmark by offering images of an unprecedented pixel density resulting in a 0.7 cm/px (0.3 in/px) GSD. This enables well-tested absolute accuracy down to 1 cm (0.4 in).

(0.3 in)/px GSD
The ground sample distance (GSD) is the distance between the centers of two neighboring pixels. For example, in an image with a 1 cm/px GSD, neighboring pixels’ image locations are only 1 cm apart on the ground. Therefore, the more pixels in the images there are, the more detailed the map and the more accurate the resulting measurements can be. In addition, since each pixel contains its own geospatial data, the higher the image resolution, the lower the absolute accuracy can be.
Higher resolution means broader coverage at the same GSD
With a 42 MP resolution, full-frame camera it is possible to fly higher and achieve the same GSD accuracy while covering more area at the same time and reducing operation costs for the capture of aerial imagery.
Higher resolution means better map reconstruction
When using a drone with a lower resolution sensor, it happens very often that map generation fails. The high resolution and low distorion lens of the the Sony RX1R II camera allow much more reliable reconstruction of orthomosaic maps and 3D models. This level of detail proves especially valuable in cases of grass fields, sand, forests or similar homogeneous patterns.
From our customers
The main advantage with the WingtraOne was the high quality images from the camera. The Sony RX1RII camera with 35 mm lens makes it possible to cover the area efficiently at a high altitude of 390 m.
