Numerous problems that are facing the experts in the field of excavation in quarries, sand pits and gravel pits can be solved by using the data collected via the aerial photos. This approach provides you with high-quality spatial information, reduces the need for field work, enables faster results, and reduces costs. The geodetic measurements, that have recently required several days or weeks by using the traditional techniques, can now be carried out in just a few hours. The procedure is fast and non-intrusive for the work processes in the quarry, without interrupting the work.

By conducting the unmanned aerial vehicle at low altitudes, we can obtain sharp aerial photographs of resolution of 2 to 5 cm/px from which every detail of the terrain is made visible. Based on the aerial photographs with advanced processing and analysis it is then possible to carry out:

• dense 3D point cloud
• orthophoto plans
• 3D digital terrain model
• measurements of surfaces, volumes, distances and heights of excavated or bulk material
• measurements of geometric features of the facilities and their identification in the photos

Moreover, the periodic aerial photography helps us to monitor and document the changes in your area, and the data obtained can be compared with a previous situation, which can benefit you in capacity planning, inventory monitoring, organizing and re-greening of the abandoned quarries, etc.
