UAV (unmanned aerial vehicle) scanning refers to scanning from aboard an unmanned aircraft.

Controlled low-altitude flight allows us to map the landforms including development and objects without generalization. The LIDAR system we use is equipped with a highly efficient laser scanner, allowing us to acquire data in a short time, with high accuracy and detail.

We create dense point clouds with a scanning speed of 240,000 points per second. We achieve 2 cm precision and 3 cm accuracy.

We set new standards for acquiring terrain data. We take measurements regardless of lighting conditions, sunlit areas and shaded areas are mapped with the same accuracy, the laser beam penetrates through the vegetation layer measuring the ground level, the high density of points allows accurate mapping of the shape and position of objects.

Acquired dense point clouds are processed in specialized software. They are aligned, filtered and classified into points lying on the ground and others.

Among a range of applications, we offer the following: digital terrain models, digital surface models, terrain profiles, cross sections, volumes calculation, contour maps, terrain slope maps, 3D and 2D visualizations.

Low-altitude photogrammetry is a technology developed and used by us to capture terrain from a relatively low altitude. Carefully planned aerial mission, suitable parameters (speed, coverage, flight height) makes it possible to obtain images with a resolution of less than 1 cm. The high-resolution cameras capture the smallest details.

Our aerial vehicles are equipped with precise RTK positioning system. We improve accuracy using ground check points and control points, so that we achieve an average position error of less than 3 GSD (Ground Sampling Distance).

Our experience and organization of work allows us to measure large areas in a short time, including places with difficult access. The specialized software and high-end workstations we use shortens the calculation process and allows us to quickly transfer the data to the ordering party.

The most important applications of low-altitude photogrammetry include: high-resolution orthophotos, photorealistic models of terrain and objects, documentation of existing state.

We make “true” orthophotos, which differ from standard ones in that they are devoid of radial displacement of objects rising above the terrain. Our products lack skewed objects and “blind spots”.
