A joint expedition of the Ludi Morya Foundation, the Russian Geographical Society, and the Hydrographic Service of the Pacific Fleet conducted a laser scan of Matua Island, which is of strategic importance for our country and the security of its borders. Based on more than 42,000 photographs and measurements of surface points in a three-dimensional coordinate system with a total volume of 300 GB, a digital terrain model, a photographic terrain plan with precise reference, and a volumetric model will be created to replenish the database of the GIS portal "Rossiya – ot morya do morya".
The laser scanning of Matua Island was performed using an unmanned aerial vehicle, on which the LIDAR system was installed. It provides high shooting accuracy. In total, the specialists scanned 56 square kilometers, the total flight time of the quadcopter was 60 hours.
“Due to the complexity of the volcanic terrain and the lack of roads, the most difficult part was to move around the island with the equipment. We covered about 700 km in total. The second difficulty was unpredictable weather conditions. In different parts of the island, the weather is different and changes in just a few minutes, so it is impossible to predict where you will have a chance to fly," admitted Daniil Bidenko, a geodesic engineer at OOO Fertoing.
“Here, in the zone of cross-influence of the Sea of Okhotsk and the Pacific Ocean, strong winds are constantly blowing. This makes it dangerous to perform almost every flight,” Bidenko added.

The results of the work are an important scientific achievement, which will allow us to study in detail the relief of the island, natural objects, and fortifications.
